What is “Renewable Energy”?

Posted by JD on November 1st, 2013 in Uncategorized | 82 comments »

I’ve recently seen some posts and articles about “renewable energy” that just didn’t ring true with me.  Give a little thought to what you consider to be truly renewable in the world of energy.  What do you come up with?  Here’s my list:

  • Solar
  • Wind
  • Geothermal
  • Wave/tide action
  • Hydropower

The Natural Resources Defense Council adds “Biomass”, but warns that it must be managed with care, and I concur.  NRDC goes on to state that “Renewable energy comes from natural sources that are constantly and sustainably replenished”.  And that’s where my issue comes in.

The articles and posts of which I spoke suggested that Waste-to-Energy plants provided renewable energy.  Yet another post said that the methane from the local landfill provided good, clean renewable energy.  Think a minute about the renewable aspects of WtE plants and landfill methane.  What’s the base fuel here?  Trash!  No way around it.  For these things to be “renewable”, we humans have to keep on creating trash.  There are a lot of programs out there aiming to reduce landfill waste, so if we happened to get to zero landfill waste (not in my lifetime, but a thought), we’d eventually run out of landfill gas.

When you look at my list of renewable energy sources, do you see any types of environmental pollution associated with them?  Not a bit.  Yes, hydropower impacts fish, but I’m talking about air pollution, water pollution.  These guys yield clean energy.  Waste-to-Energy plants usually involve combustion of the waste, which is in no way clean; with the wide variety of wastes in the fuel stream, air pollution control equipment is pushed to the limit to minimize pollutants out the smokestack.

Now, there are advantages to WtE processes, sorta.  There is potential, emphasize potential, to capture the products of combustion.  If this waste went instead to landfill, much of it would degrade, in the anaerobic conditions in a landfill, to methane gas.  Landfills are required to have methane collection systems, which is fine, but they collect nowhere near all of the methane generated, so it escapes to the atmosphere.  You don’t hear much about methane being a greenhouse gas (carbon dioxide gets most of the press), but it’s several times more potent than see-oh-two.  The only good thing is that its atmospheric residence time is around, I think, 12 years, much less than that of carbon dioxide. But, at the end of the day, we generate trash, and from that we get either atmospheric pollution from the products of combustion or the generation of methane.

So now when you hear the claims of WtE being a renewable energy source, you’ll know better.  And you’ll be able to recognize a form of “greenwashing”, where nice environmental claims are made for a system or process than is not environmentally nice.  Like “Clean Coal”, one of my favorites.

    For me, the most viable alternative energy source is solar power. The devices and gadgets, such as solar lights and panels, continue to be more affordable as days pass by, making them affordable to even financially-challenged families and communities. Hopefully, the US government will focus more on the propagation of the uses and benefits of solar power in order to entice more people into using it.

    Most renewable energy comes either directly or indirectly from the sun. Sunlight, or solar energy, can be used directly for heating and lighting homes and other buildings, for generating electricity, and for hot water heating, solar cooling, and a variety of commercial and industrial uses. Thanks for sharing wonderful article based on this we need to utilise this type of energy in our day to day life as well.

Arm-wrestling with Climate Change

Posted by JD on June 4th, 2013 in Uncategorized | 24 comments »

Ad hominem attacks

 

What does it take for people to connect with climate change, or as one researcher puts it, global change? Many people feel that there is a significant disconnect between the scientific community, which tends to keep its collective head down, doing research and publishing papers, and the public at large. The public is much more likely to hear from the skeptic/denier community than the scientific community.

An analysis recently published in the journal Environmental Research Letters (http://bit.ly/14tzcHo) reviewed over 4,000 abstracts of peer-reviewed papers written since 1991 that took a position on human-caused global warming. Of these 4,000 abstracts, 97.1 percent endorsed the consensus that humans are causing global warming. Yet we are more likely, in my view, to hear about the 2.9 percent who don’t support the notion of human-caused climate change. You can read my post on “Merchants of Doubt” to learn more about that.

A local sent a letter in to the editor of the Napa Register a few weeks ago, complaining that Scientific American wasn’t telling the whole truth about climate change, that they were leaving out selected pieces of information that didn’t support his skepticism about the issue. I thought it’d be fun to follow the comments, and I was right.

I was not surprised to see folks jumping in with ad hominem attacks (e.g., a guy boasting of a master’s in political science (really? Poly sci?), so he knows how this works and you don’t), significant broad brushing of human-caused climate change (aka anthropogenic global warming/AGW) being a liberal campaign to throw the free market in disarray, and similar. When folks would bring up specific scientific issues, the denier response would be “that’s wrong” with no evidence to support the claim.

The deeper I went, the more interesting it got. One guy claimed that a Fortune magazine (no conservative bias there) article, which supposedly cited a peer-reviewed paper, established that there has been no warming in the past 10 years, therefore the AGW thing was bunk. I reviewed the Fortune article, which seemed to have the term “alarmist” in every paragraph, then looked at the article that it cited. It was quite a stretch to come to the Fortune conclusion of “no warming” from that article, which largely talked about different forcings and the difficultly of obtaining consistent data. But this commenter thought it was the be-all-end-all, and got rather huffy when I posted a note asking if he had actually read the cited article. He didn’t answer my question, but got huffy regardless.

There was quite a lot of banter about liberal conspiracies in the comments. Every time somebody posted about research findings that supported aspects of AGW, the rantings about liberals undermining the world would come out. And there were many retorts along the lines of “you’re stupid because you disagree with me”. These folks really play nice.

The fun part was when one guy found a piece (on Yahoo search, of course; seems to be the “go-to” for deniers/skeptics with no scientific background) about a recently-published article that claimed that cosmic rays were to blame for global warming, not humans and CO2. He paraded this around quite a bit. Never mind the 97 percent of the papers that support the consensus on AGW: this paper from the three percent shows that they’re all wrong. It took very little time for someone to point out that the paper’s author had brought up this theory before, and it had been thoroughly debunked at that time. Apparently he had new information that encouraged him to try again. I note that the skeptic community frequently claims that editors of peer-reviewed journals will not publish papers that take issue with AGW, but this researcher had the same poorly-received theory published not just once, but twice. Maybe I’ll keep that in my back pocket for the next “they won’t publish contrarian papers” claim. Could be fun.

It’s fine to take issue with global warming. Atmospheric science, oceanography, and similar are tough subjects to get one’s arms around, and it can be frustrating. But that doesn’t mean that you should reject it out of hand. Do some reading, find articles that are based on the literature, whether it’s the 97 percent or the three percent, but try to inform yourself. Send me a note if you are interested in readings aimed at the layperson, as I’ve read several and can make recommendations (a research scientist I am not). Take a position, but do make it an informed position.

    I’d like to read those “layperson” articles about global warming. I think the people on both sides of this argument have been sniffing banned substances. So, reading something that doesn’t sound like it comes from a zealot with an axe to grind would be interesting and maybe enlightening.

    In the 1970′s and 80′s it was “global cooling” and the “coming mini-ice-age”. Then it was the ozone hole and global warming. Now, since the “warming” has appeared to slow or have stopped altogether, the problem is called “climate change”. Which one is it?

    After reading through the wiki-leaked memos from the IPCC and knowing the back biting, petty attitudes of many of the people who would write those “peer reviewed” papers you speak of, I don’t trust any of them. Call me a simpleton, or whatever. I’m not about to take the “word” of people who would change their underlying data to support a point of view. Those actions tell me that they would lie about trivial stuff as well. And on their word we’re supposed to endure all the “carbon tax” red tape and costs? I hope that doesn’t happen.

    Unfortunately I can’t get “my arms around” the whole man-made global warming thing. I see the polar caps receding (like my hairline) and also see that some of the areas that were “melted clean to bare earth” that are starting to come back. I’ve also seen articles make a big deal out of it, but fail to mention that it happens regularly, every few years, or in some areas, every year. So, the pictures make for good backup to articles that provide “slanted” facts.

    As an “uninformed” individual, who is easily confused, I don’t appreciate being “enlightened” by some well-credentialed expert when I find out later that he only told part of the story — the part he agreed with. The rest of the story is that the science isn’t settled because the theory doesn’t appear to match the facts.

    It’s tough for me to reconcile man-made pollution from our little patch of land with the ginormous emissions from massive wild fires, the pollutants belched out of the active volcanoes around the world, the pitiful amounts of destruction in the rain forest and the pollution created by China and third-world countries who will be generating their power from coal for the next hundred years.

    If you have some “understandable” sources that explain what’s going on, I’d be interested.

    Regards,

    Gus –
    It’s a little tough making a recommendation for you as you suggest that you don’t trust scientists. However, I think Orren Pilkey does a good job of presenting the evidence in a pretty accessible manner. He also looks at counterclaims and explains why, in his view, they don’t work out. His book is “A Global Warming Primer”, available on Amazon.

    You mention a couple of things that came out of the popular media that had, at the time, little basis in fact, but folks who aren’t comfortable with global change tend to point back at them as evidence that climate predictions tend to be overblown. The whole thing in the 70s about a new ice age seems to come from a few conference presentations and papers that suggested a cooling trend, and Time and Newsweek took this and ran with it. There wasn’t a lot of good information on temperature trends in the early 70s, but, as the information improved, even by the time that these articles ran, the Ice Age folks were a small minority of the researchers looking at climate issues.

    I’m thinking that your comments about IPCC may actually refer to the hacked e-mails from researchers at the University of East Anglica. Three separate investigations showed no real bias in the work, more like researchers venting frustrations. As for IPCC, a early draft of the upcoming 5th report was leaked, and the denier community apparently latched on to and misrepresented one paragraph to suggest that there have been no recent temperature increases.

    Reality seems to be that there have been global average temperature increases over the past 15 years, with 2010 being the hottest year.

    I think that many of your questions are addressed in Pilkey’s book. Most of the issues are also addressed at http://www.skepticalscience.com.

MedShare is Coming to UCDHS – Finally

Posted by JD on May 10th, 2013 in Uncategorized | 10 comments »

In my last post I wrote about the challenge of bringing a new program on board which, as I wrote, doesn’t necessarily color within the lines. MedShare represents a great opportunity to put our surplus medical supplies to great use in 3rd World countries. Stuff that we can’t use, and therefore discard, can save a life in a poor country.

As I concluded in the last post, there was light at the end of the tunnel, with Bob Waste suggesting that we simply change the “donation request” to a “sponsorship”, and have a check cut for such a sponsorship to MedShare. Off we go? Not.

This may be a bit of TMI, but it serves to illustrate some of the intricacies, and, therefore, challenges of our system. Traditionally it has been easy to simply prepare a check request for a sponsorship, which is a good thing since Community Relations sponsors a couple of hundred events and activities a year. I can just imagine what a hassle doing a purchase requisition for each sponsorship would be. Well, guess what happened. Campus Accounting decided that they needed to track sponsorship via the purchase requisition process, and apparently told us that we had to do the same. This slammed the brakes on for a number of sponsorship requests, not just mine. Our purchase req system is not designed for sponsorships, and our Purchasing folks, rightly so, said that purchase req isn’t the right way to do this.

After a bit of back and forth, the two sides got together a few weeks ago, while I was off at the CleanMed conference. The upshot? Campus didn’t know that our Purchase Req system didn’t mirror theirs. They were holding fast because they thought it did. Apparently they agreed to let us handle sponsorship our way, in the check request process. All is now good.

Now MedShare has our sponsorship check in hand, Bill Corbett has processed a purchase order, and we are seconds away from being good to go. My intern, Joanne, and I talked with our MedShare rep, Shannon, the other day to get a handle on logistics and to lay out a plan to put things in motion here.

We have several (30-40) pallets of surplus medical supplies in the warehouse, all of which came back from PHS exchange cart restocking. The warehouse is anxious to get this space back. I just received an e-mail from Shannon, telling me that they have a trucking company that will backhaul these pallets of goods to them, pro bono, so we should get the warehouse freed up next week.

The kick-off meeting is being scheduled for May 20, and the following day we’ll receive shippers which we can fill with accumulated supplies for shipment to the MedShare warehouse. Then we’ll figure where to place the collection barrels, while, at the same time, contractor badges will be processed for the MedShare driver and operations manager.

No small amount of work, and it really did take a village to get this thing going. But, this time, we really are ready to go. Pretty exciting!

    We work in the healthcare logistics and equipment relocation. Minimizing waste and repurposing surplus supplies is a need we see every day. Finding commons sense solutions for our clients helps them, helps us and the environment. I would be interested to get updates on the evolution of this program.

    I enjoyed the last post you done. This was was as equally impressive. Keep it up.

The Challenge of a New Initiative

Posted by JD on April 11th, 2013 in Uncategorized | 2 comments »

It is interesting to see how a big institution like UCDHS reacts to a new initiative that doesn’t color inside the traditional lines. I made a presentation to the Sustainability Subcommittee earlier this week called “The Trials and Tribulations of a Sustainability Initiative”, which reviewed one such adventure, best characterized as “one step forward, two steps back”. Come along for the ride, and see how the forces of good can overcome the forces of business as usual.

I was at the CleanMed conference last year, cruising the vendor booths during a break in the action (yes, there is action at a sustainability conference!), and came upon the MedShare International booth. MedShare is a really cool non-profit, based in Atlanta with a satellite in the Bay Area. They solicit donations of surplus medical supplies and equipment from hospitals and other health care entities, collect it all up, have volunteers sort it out, and ship the materials to appropriately vetted hospitals in 3rd World countries. What’s not to like? I chatted with the NorCal director, Chuck Haupt, and we agreed to stay in touch.

I was intrigued. Leigh Clary had told me about her process of collecting surplus supplies in the ED, trying to keep them out of the trash. There were rumors that a resident, Dr. Ha, was doing similar in the OR, working with a non-profit that he knew from his Yale med school days. And I had also heard about surplus supplies finding their way from PHS to the warehouse, where they would be sold or donated to non-profits. It really seemed like we had an opportunity to leverage a relationship with MedShare to formalize a donation program, one which would both divert surplus supplies from the landfill, and provide a great community benefit. Let’s do it!

So off I went, figuring out how to make this happen. I talked to Purchasing about how we could have a business relationship with MedShare, and obtained buy-in from the various folks who were working to divert these surplus supplies from the landfill so they could fulfill a better purpose. Distribution’s Troy Taylor was particularly excited, as many pallets of surplus supplies were sucking up valuable space in the warehouse. Finally, COO Vincent Johnson gave his approval to move ahead with the partnership. Off we go!

One potential roadblock was MedShare’s request of a $200/week donation to support the collection and transportation of our materials. Seemed fair to me, as it’s quite a hike to their warehouse in San Leandro, and much time would be spent by their driver going around to our many locations to collect the materials. I received guidance from a few key people on the donation, and it seemed like I had everything going in the right direction. A kick-off meeting with MedShare and UCDHS was set up, and the collection process was just weeks from commencing. Or so I thought.

Purchasing’s Bill Corbett sent me a note, suggesting that we conduct another review of UCD and UCOP policies relevant to the partnership with MedShare. Upon review, Bill thought I might be pushing the envelope a bit on this, and opined that I should get approval from campus Bargain Barn before I went any further. “Why?”, I asked. “This program saves stuff from the trash. What’s the Bargain Barn have to do with it?” Common sense intervened, and I called the Barn’s Katie Jaramillo to get her blessing for the program. A blessing is not what I received, however. Turns out that the Barn had been selling this stuff, not for much money, but selling it nonetheless, and there was a specific process for donating those materials that could not be sold. Unfortunately, the partnership with MedShare did not fit into this process, and I had to back down.

I postponed the kickoff meeting, and started to consider approaches for working around the Barn’s requirements while still keeping peace with the Barn. I was moping about this quandary for the better part of the week, but then, out of the blue, the phone rings. “Hi, John. It’s Katie Jaramillo, and I have good news for you.” Really? Really. Katie had discussed the situation with Janice King, the UCD Director of Materiel Management, and they decided that the little bit of money they received for the surplus supplies really wasn’t worth the Bargain Barn effort, which effectively reduced the value of the supplies to “de minimus”. De minimus (negligible value) provides the flexibility to engage a non-profit for distribution of the goods. The following day, Janice e-mailed a narrow exemption to policy to me, effectively permitting the partnership with MedShare to move forward. Yay, Katie! Katie was immediately gifted with a box of my chocolate chip/oatmeal cookies for her efforts.

Things were suddenly looking really good, but there was still one obstacle to overcome: that pesky $200/week donation for transportation support, which MedShare requested to be paid a year in advance. The donation was already a bit contentious when the project went off the rails. There are essentially two ways to pay for things: via a check request, or via a purchase requisition. It seemed that the check request folks felt that a purchase requisition was necessary, as that’s the way that donations are now handled on campus, and Purchasing said that a purchase requisition didn’t fit into policy regarding donations. Back and forth, back and forth. I’m sure that Bill Corbett got tired of seeing my pathetic face in his doorway. He tried to help, but felt that current policies tied his hands. Ross O’Brien in A/P did a lot of work on his end to assist, but we all ended up stuck in the middle.

As I noted in my presentation, sometimes policies just aren’t geared to take advantage of new opportunities.

I was discussing this with Bob Waste, who’s in charge of government affairs and community relations, and he had a great idea. His group provides sponsorships to a number of efforts that benefit both the community and the Health System, and it appeared that this “donation” was, in fact, a sponsorship of the MedShare partnership. If we reframed it as such, getting a check request approved should go much more smoothly.

Off I went to rework the agreement with MedShare, and the check request is now in the works. There are still a few loose ends to tie up, as I need to register MedShare with the Bargain Barn as a recognized non-profit, and there will be no shortage of logistics to figure out for the collection process. And, of course, submitting a check request is no guarantee of having a check in hand, but I think that most of those bumps have been smoothed out.

It’s been an interesting ride, and quite the learning process. For one, asking for forgiveness instead of permission probably isn’t the best way to go when wrangling with UC policies, for what appears to be wiggle-room can turn out to be the Vulcan Death Grip. However, some really good people came through to save the day, and I’m hopeful that we’ll be in full partnership with MedShare before the summer solstice arrives. It’ll be great to know that those boxes and boxes of surplus medical supplies will be supporting the efforts of a 3rd World hospital instead of filling up a landfill. Sometimes it all works out, in spite of my best efforts to foul things up.  :)

Check out the MedShare website, and…

    Kudos to you!!

    The company that I work for also tries to do a lot of outreach and frequently it looks as if doors are being shut and then some angel comes along and saves the day. I can’t think if a much better cause than 3rd world hospitals, they need all the help they can get.

    Keep up the good work….hopefully it will be easier next time!

The Challenge of Climate Change: The Merchants of Doubt

Posted by JD on March 13th, 2013 in Uncategorized | 3 comments »

I’ve been wondering why people aren’t paying more attention to climate change. One doesn’t have to look far to see the effects of a warming global environment, such as the record heat, drought and fires that have recently plagued Australia. Consider, too, the possibility that the Arctic may be relatively ice-free during the summer sometime soon. And it’s quite likely that Superstorm Sandy (too big to be a mere hurricane, it became a “superstorm”) was the product of our changing climate.

Earthrise

Earthrise

It seems that one of the reasons that we aren’t paying sufficient attention to the global warming issue is that we have a tendency to only regard things from the perspective of how they directly affect us. Temperature goes up a few degrees, we dress for it or turn up the A/C. What’s the big deal? In many ways, it’s the indirect (to us) effects about which we should be concerned. Relatively small changes in average temperature can dictate when plants can be pollinated, where grains can be grown, whether insects are active or dormant. Increasing the average ocean temperature a few degrees can make a day at the beach more comfortable, but it also rapidly increases the rate of melting of Arctic Ocean ice and Antarctic ice sheets, which in turn raise sea level. So, yes, a couple of degrees Centigrade increase in average global temperature is a big deal.

We also tend to dismiss issues that don’t immediately affect us. Ours is a society that tends to want instant gratification, so if it’s not happening within a week, we ignore it. With climate change, many changes happen slowly, over decades, so immediate effects are not seen. The problem here is that once we can really see the overt changes, having ignored the warning sign events such as those mentioned in the opening paragraph, it’s too late for us to change our practices in any meaningful ways. We will have gone well past the tipping point, and our course will be set.

Then the question comes up of “How do we know that it’s us?” It’s a legitimate query. We hear how the sun goes in high and low cycles, that the earth has been substantially warmer in the distant past, that it’s been relatively cooler recently, and similar. Scientists who specialize in climate and earth sciences have looked at all of the known potential causes of the current wave of global warming, and there is substantial consensus that we are the cause, largely through our burning of fossil fuels and the resulting emission of carbon dioxide. The whole chain of events features a large number of variables and “if this, then this, unless this…” scenarios. It’s dense, and tough to understand. We need to trust the scientists who make such investigations their life’s work, and seriously consider the paths that they recommend.

There are a number of people who disagree with the “humans are causing climate change” message. Obvious among them are the fossil fuel companies, particularly coal. Coal is one of the worst players in the climate change game, and, as it has been suggested that the best way to avoid climate catastrophe is to shut down coal-fired power plants, the coal companies are working hard to discredit the climate change message. Much of the business community likes “business as usual”, as it’s how they make money, so they, too, fight against climate change messaging and legislation. There are a number of other big players, with deep pockets and seemingly selfish agendas, who push back hard on the climate change issue.

I recently read a book which describes the way that business works to discredit messages, and messengers, that would negatively impact the bottom line. It’s called “Merchants of Doubt”, the title suggested from an infamous tobacco company memo which stated “Doubt is our product”. The book shows how just a few people, well-placed and well-funded, can work with a goal of discrediting scientists and any others who dare to advocate policies that would be detrimental to business interests.

What I found interesting in “Merchants of Doubt” was the thread that wound through the big “health risk versus business” public policy debates, starting with the link between tobacco use and cancer in the 1960s and continuing to today’s anthropogenic global warming. Four guys from the Cold War era of the 50s were at the core, using their credentials as physicists and knowledge of the system to cast doubt on the tobacco-cancer association. As that died down, they attacked the scientists who suggested a link between CFCs and the hole in the ozone layer. Moving right along, the group went after assertions that second-hand smoke was associated with various diseases, including cancer. It didn’t matter that they weren’t subject-matter experts in any of these areas. They portrayed themselves as concerned scientists who wanted the public to know the “truth”, taking the tiniest grain of perceived scientific inaccuracy and spinning it into a full-blown controversy. These guys reportedly hated government regulation, which they equated with the socialism that the battled in the 50s, and were happy to let the free market trample over the common good. That they eventually lost each battle meant little, as they simply went on to cast doubt in other areas.

The men at the core of this activity are either inactive or no longer with us, but the process remains intact, well-funded by big business interests such as the Koch brothers. The current target is manmade (anthropogenic) climate change, and they are casting doubt with great zeal. Climate change is an easy target for this group, as the numerous and complex variables present great fodder for questioning the science and the scientists. You might have heard of “Climategate”, where the e-mail accounts of many climate scientists were hacked and made public. Some out-of-context comments were heavily publicized as evidence that climate change was simply an antibusiness conspiracy. While several subsequent investigations have shown that such was not the case, the taint of “Climategate” remains. Or consider the outcry against climate scientist Michael Mann’s graph of temperature increases since the 1900’s, the now-infamous “hockey stick”. It was very legitimate science, pilloried by the denialists. Since it’s kinda tough to wade through the science, it’s easier to agree with the doubt-throwers than it is to do our own research…at least that’s what they hope we do.

I encourage you to give some thought to the climate change issue. Take a bit of time to consider whether you are hearing scientific consensus or a simple ad hominem attack on the messenger. Is there more credibility with peer-reviewed scientific evidence, or the cry of “you’ve got it all wrong” without the support of a plausible alternative scenario?

Over the next several weeks I will be posting on climate change issues, including causes, anticipated impacts, and the steps that the University of California and our own Health System will be taking to minimize our impact on the climate. I hope that you take the time to read and comment. To fight climate change, we will have to change our way of life, eschew “business as usual”, and understand that we can’t grow forever. We will have to recognize some new limits. We might not live to see the results from inaction, but life will be very different a couple of generations from now if we do nothing. Should that be our legacy?

    JD – Great article. Makes me think of Michael Crichton’s State of Fear… whichever way you lean after hearing those ideas, I think we can all agree there is big money to be made on both sides of issues that garner national/global attention. Anywhere big money is involved, there will be some pretty strong pressure to control perspectives. I agree people should make informed decisions for themselves after personally reviewing the evidence, while at the same time keeping perspective the immensity of the systems involved in ‘climate’. The ‘A’ causes ‘B’ causes ‘C’ simplicity we love as human beings (because we feel like we can understand it and control it) might not be an accurate representation of reality. I do take comfort in knowing that real change starts at the individual level – that if each of us simply chose to do what we were going to do anyway in a ‘better’ or ‘less harmful’ way, we might actually be able to make some significant, positive changes in this world. Looking forward to hearing what the UC system is planning!

    I have come to the conclusion that we all have a little blame global warming and its consequences and guilt even more politicians who do not slow down.

A “Better Mousetrap” for Recycling?

Posted by JD on March 1st, 2013 in Uncategorized | 19 comments »

Apparently Houston has an annual “great idea” contest, or something similar.  I subscribe to a couple of recycling listservs, and a member posted a link to the contest with a request that we vote for the recycling idea.  I’m always searching for better mousetraps, so I sped over to the Houston site to find out what this next great new thing could be, and was surprised to find that it was a throwback to the days of yore.  It’s called “One Bin For All”, featuring the idea that you could dispense with source separating of recyclables, trash, yard waste and all that, and simply put it all in one bin.  Heck, that’s how we did it when I was a kid, and it all went to the (open) landfill. 

Houston seems to think that it has a better mousetrap with its assumption that Waste Management, Republic Services, or a similar big waste management company will sense the vacuum here and rush in to build a new, beyond state-of-the-art material recovery facility (MRF) that will happily and cheaply sort all this stuff out.  My response to this post was: “One Bin for All. Nice idea, we’d all love to see it happen. But first, show me the MRF.  Sounds like a Dirty MRF to me. We separate trash from recyclables now to reduce contamination. How the proposed MRF handles the pint of pasta sauce spread all over the paper and boxboard will be key. Show me the MRF.” 

Several other responses were along similar lines.  Others pointed out a return to the “easy to throw things away” mentality that we’ve been pushing so hard to change into “Think before you toss”.  With the easy to throw out option, you stop asking manufacturers to make items that can be readily recycled, because everything simply disappears down the same hole.  This process is not going to increase Houston’s waste diversion rate; I’m betting that it will actually decrease it.  The claim that this process will increase diversion to 55% initially, and eventually to 75%, really requires a suspension of disbelief. 

Recycling is a tough business.  After the recyclables (well, we hope they are all recyclable) disappear into the bin and the truck, they do not magically turn into new products.  The MRF is key, with a combination of people and equipment sorting the various plastics, metals, papers, cardboard and such.  A great video of a MRF in action can be seen here. Many MRFs are not as sophisticated as the one shown here, so fewer items are recycled, or additional people power is required for the sort line. 

Recycling won’t work unless there is a market for the materials.  These items are commodities, and value goes up and down.  Once the value of a particular material drops below a certain point, the market disappears, and suddenly the MRF operator is stuck with a bunch of material that can’t be sold.  Additionally, as the video notes, buyers want specific types of items, and they want them free of contaminants that can foul up their manufacturing processes.  That creates two challenges for us. 

Contaminants come in many forms.  One, as mentioned in my comment, above, is foodstuffs, oils and similar contaminating plastics, cardboard and paper products.  Toss a quart of used oil into a bin of paper, and the value of that paper goes to zero: off it goes to the landfill.  Another is the challenge of dissimilar materials in one discarded product.  A good example is the type of disposable “warm-up” jacket used in our ORs.  Made of spun polypropylene, it seems that they’d be an excellent candidate for recycling.  Until you notice that the stretchy cuffs are of a different material, as are the snap closures.  The buyers don’t want these various materials; they’ll take only the polypro without the snaps and cuffs.  As it is impractical to cut out these items, the warm-up jackets are landfilled. 

So is Houston’s “Better Mousetrap” for real, or is it a sham?  I can tell you that our vendor, Allied Waste (part of Republic Services, the second largest waste operation in the US), opened up a new, state-of-the-art MRF in the East Bay several months ago, and they still don’t want contaminants in our recycle bins.  The new MRF does a better, more efficient and more automated job of sorting out the recyclables, but it hasn’t opened the door to more types of recyclables, and it doesn’t want our trash.  We still have to do a good job here. 

Houston, you have a problem.

    Update: several listservs posted yesterday (3/14) that Houston was awarded the $1 million Bloomberg prize for the “all in one” recycling proposal. Good luck with that.

Some Thoughts on Red Bag Waste

Posted by JD on February 21st, 2013 in Uncategorized | 5 comments »

I figured that, at some point, I’d blog on red bag waste, or, as it’s commonly known, Regulated Medical Waste (RMW), but I thought I’d first spend time on issues that are more obviously associated with sustainability. However, I’ve started a benchmarking project in which I compare UCDHS’ sustainability performance with that of winners of the various Practice Greenhealth (PGH) awards. Among other things, PGH looks at waste diversion practices, and includes RMW among these. So I did a few calculations and extracted some data from our 2013 award application, and compared it to the RMW information in the PGH 2012 Benchmarking Report.

Conclusion: We’re horrible.

Really, our numbers are so bad that we all should be embarrassed. Yes, we can talk our way out of it a bit, as we could take out the RWM generated in research functions, but it’s not that much. The reality is that we tend to use the red bag as a general garbage can, and some people tend to discard items as RMW when they could go to regular trash. In general, many of us are WAY too conservative when determining whether an item should be managed as RMW. Take a look at the numbers that follow, and you, too, will be embarrassed.

Practice Greenhealth has three different award levels. In 2012, we, along with 79 other hospitals, won the Partner for Change (PfC) award. Next level up is PfC with Distinction, which was awarded to 41 applicants, including UCSF. At the very top is the coveted Environmental Leadership Circle (ELC) award, won by 28 hospitals. For evaluating waste generation, Practice Greenhealth uses weight per adjusted patient day. For 2012, the average RMW generation for PfC winners was 3.3 pounds/APD; for PfC w/Distinction, 2.2 pounds/APD; and for ELC, a stingy 1.5 pounds/APD. The weight shown on our 2013 award application is 9.0 pounds/APD. Nine pounds of RMW per Adjusted Patient Day!

We’re horrible. But with “horribility” comes opportunity, as I will illustrate later.

We should be happy that they even let us submit an award application with RMW numbers like that. Don’t think that the folks at PGH don’t notice. This past Saturday I received an e-mail from awards coordinator Lin Hill:

Hi John,
Loved your application. A couple questions.
Your refuse/APD is half what UCSF is and close to some of our other award winning universities, (impressive), but your RMW% of wastestream is almost 3x theirs.
Why do you think it’s so high?
It seems like an opportunity for great cost savings.
Lin
 

Lin, PGH’s Janet Brown, and I discussed RMW last month on a conference call, and they were astounded (“surprised” isn’t strong enough) to learn that we have red bag bins in every patient room. I used to think that this practice was normal, but, when my wife was inpatient at Napa’s Queen of the Valley a few years ago, I learned otherwise. I quickly noticed that there was no red bag bin in her room. Instead there was a roll of small red bags in a drawer, and when a nurse had to dispose of some RMW, she put it in one of the bags, tied it off, and walked it to the soiled utility room. What a concept! It turns out that this same practice is used by UCSF Medical Center and UCLA’s medical centers, where it contributes to their low RMW numbers.

There also seems to be an overabundance of caution when deciding whether or not an item needs to be managed as RMW, which has been noted by many of us in EH&S. We’ve often fielded questions about RMW, particularly from nurses who suggest that colleagues are placing innocuous items in the red bag. This tells me that 1) it’s too easy to “over-redbag” items, and 2) guidance on what constitutes RMW needs to be more accessible.

The general policy on RMW is found in Hospital P&P 2005, with Attachment 1 addressing “Medical Waste Classification”. To me, this information is a bit too dense, making it hard to tell whether or not something should be handled as RMW. Nicole Mahr, RN, an Infection Preventionist with whom I’m working on this issue, says there is a reluctance to get too detailed in a policy, which, in my view, reflects the long turnaround for policy updates which makes timely changes a challenge. We were specifically discussing disposable isolation gowns, which apparently are often red bagged as a matter of practice. Nicole will be preparing a blog for First Tuesday that will address proper handling of used isolation gowns; we’ll see that, in most cases, they should go to trash, not red bag.

This issue of the overuse of red bags needs to be addressed, and Nicole and I will be leading an ad hoc work group to put together, once and for all, accessible red bag waste criteria that we’ll make readily available to all. We’ll address what qualifies an item for the red bag, and will look at common items, like isolation gowns, that all too frequently are handled as RMW.

One last thing that I’d like to mention is cost. Until September 2011, we treated most of our red bag waste in microwave units at the Back Dock. The costs of this process were not documented, and it seemed to create an environment that suggested that there was no cost to treating our red bag waste. However, with our current waste management processes, it costs $0.19 per pound to treat red bag waste. On the other hand, general trash is about $0.04 per pound, making it five times more expensive to throw something in the red bag that doesn’t really belong there.  Some food for thought: we paid over $400,000 in 2012 for management/disposal of RMW.  We should be able to make a significant dent in that if we get our act together.

As you can see, there are a lot of opportunities to improve our RMW management practices that will help us reduce our red bag waste, save money, and move in step with other medical centers in the UC system and elsewhere. Let me know if you’d like to participate in our work group. I’ll bet we can get below 5 pounds RMW/APD in a year. Can you help us achieve this worthy goal?

    JD: I came across your blog while doing research for a project on sustainability and waste reduction in health care, and looking to see what we’re doing here. I’ve worked at UCDHS for nearly 20 years and am currently the Vice-Chief of the Medical Staff and had no idea we had a Sustainability Administrator! I have long thought that we were very lax about red bag waste. I am interested in participating in your work group. We need to do this. I’ve done some homework and have some ideas. I bet our resident medical staff committee will be happy to get involved, as well. Let’s galvanize the troops! We can do the right thing and save money, too… what’s not to like?

    I have come to the conclusion that we all have a little blame global warming and its consequences and guilt even more politicians who do not slow down.

The Paper Use Reduction Act

Posted by JD on February 12th, 2013 in Uncategorized | 44 comments »

Some of us remember that back when computers first became really popular, there was a lot of chatter on how we would become a “paperless society”. Wonder how that’s working out. Looking around our workplace, it seems like more paper, not less, is used on a regular basis. If the Health System had a Legislature or similar, I’d lobby to get a “Paper Use Reduction Act” enacted. When you understand how much paper we use, it’s really an eye-opener.

Stack of PaperOne of the questions new to this year’s Practice Greenhealth award application is “How many reams of paper do you use in a year?” Hmmm, I never gave that any thought, but I figured that I knew where to get the answer. I sent a note upstairs to Bill Corbett in Purchasing: how many reams of paper did the Med Center use in CY 2012? It turns out that it wasn’t a straight shot, as Bill queried someone in Material Management on campus, who, in turn asked the rep at OfficeMax. They were nice enough to send over a spreadsheet, which was important, as some data was in reams and other in cases (10 reams to a case). Once all the calcs were completed, I had the answer: 128,000 reams of paper. A ream holds 500 sheets, so, when all is said and done, that’s 64 million sheets of paper. Whew!

I was similarly surprised to see that there were over 200 line items on that spreadsheet. Granted, some were the same item, one line for case count and another for purchases by the ream. But I really have to wonder if we really need such a selection of paper. Sure, there are different sizes, and some in color, but I’d wager that 90 percent of our work comes out on 20# 8½ x 11 white copier/printer paper. And all of that should be on paper that is at least 30 percent post-consumer waste content (PCC), which means we’re giving the paper that we recycle a home. Most of our machines work just fine printing on 100 percent PCC paper, and I was heartened to see that quite a bit of the paper used was of this type. While the spreadsheet didn’t provide enough information to do a good drill-down, it looks like well over 75 percent of the paper used was at least 30 percent PCC, a good start!

One of the things that the Act would have us do is to emphasize electronic communication. A nurse recently asked me if I realized that some nurses print out every e-mail that they receive. I wonder why they’d do that. And why don’t the clinics e-mail the appointment reminder to me instead of wasting paper and postage by mailing it? At the conclusion of my appointment last week, I asked to “opt out” of the mailed reminder, and learned that opting out was not an option, as the system is set to automatically waste paper and postage. I also wonder why Training & Development, among others, sends out a ton of flyers for upcoming events instead of doing a mass e-mail. Finally, since I contribute to the Cancer Center, I get a lot of follow-on four-color glossy mailings. This would be a fine thing to receive as a PDF file via e-mail. I’ll bet that this is just the tip of the iceberg as far opportunities for saving paper via electronic communication goes.

The Act would also require all computers/printers to be set up for duplex (double sided) printing. I was complementing the guy at the clinic the other day about double-side handouts, and he said that he had to do those at the copy machine since his printer wasn’t capable of duplexing. Ack! He also noted that (what I assume to be) EMR did not have an option to print documents double-sided. Double-ACK! It’s a shame that conservation processes do not appear to be considered when setting up these complex programs. Discharge orders are similarly crazy. I was inpatient a few years ago, and was amazed to see that my discharge orders were not only printed single side, but the last several pages had only headers, with the page blank, no text (as I had no orders under those headers). Now that is ridiculous. And those are just examples that I have personally witnessed. We have to do better than that.

While I mentioned it under “electronic communication”, above, the Act would explicitly require an “opt-out” option on all processes, with you typically opting-in to receive documents electronically. This could cover appointment reminders, handouts, fundraising follow-ups and similar. It makes sense to me.

Finally, the Act would require us to “think before we print”. We often see this reminder under the signature block of e-mails from our green-thinking colleagues. Does the document need to be printed, or is it just as well saved to your thumb drive? I will admit that I’m old-school about reviewing documents: I prefer to print them out so they can be attacked with highlighter and red pen. Then, of course, I transfer my edits and thoughts to “strikeout and redline” on the electronic document. I’m hard to train, but I do think about it, and try to limit my printing for editing. If I can do it, you have no excuse.

Think about how you can streamline, minimize and otherwise make paper use more efficient in your work area. You’ll save money (paper, toner, postage) while taking some stress off of the environment. Send any good ideas that you come up with to me.

And what if you want to put the “Paper Use Reduction Act?” into play? That’s easy: Vote for me.

    Hi. Thanks for the great post. I also like to keep the printouts to a minimum, but sometimes it is still best to read a report etc on hard copy. What I like to do, when I have misprints, I won’t throw the paper away. I’d either use the unprinted side as note paper, or re-use the unprinted side for other prints.

  • David Jelks

    Just wanted to say that your article is very timely. I am in the print industry and always looking for paper that is at least 50% recycled. Most of the products the we use are recycled paper. We also use soy based inks. Keep on spreading the word.

Where Do You Get Your Drinking Water?

Posted by JD on February 4th, 2013 in Uncategorized | 12 comments »

Seems like a question begging for an easy answer: where do you get your drinking water? In this case, frame your answer with “at the Med Center”. There are lots of options, including the bathroom or kitchen sink, drinking fountain, water cooler (bottled water), or small bottles that you either bring from home or purchase here.

Many people dislike the taste of the water that comes from a tap. While you can be confident that this water is safe to drink, let us not confuse “potable” with “palatable”.  I can tell you that the tap water where I live is a bit off-putting (but the hose was a fine source when we were kids!).  The same goes for drinking fountains, which use tap water for a source. Do ours have filters inside? Perhaps, I don’t know. If they do, are the filters serviced? No idea, but I’ll ask Charles Witcher, Manager of Plant Operations and Maintenance. OK, it turns out that some fountains have filters, others don’t, and filter maintenance is somewhat expensive.

What is interesting to me is where patient drinking water tends to be obtained in the inpatient areas. Several weeks ago, when we had the water system incident that disrupted water service in the Main Hospital, I participated in the response. I was surprised to learn that water for patients is often obtained from the ice machines, as each machine has a filter in it, helping to make the water taste better.

How many of you get those pints of bottled water from vending machines or bring them in from home? Aren’t they convenient, particularly if you’re not fond of tap water?  Have you considered the environmental cost of this convenience? Among others, the Pacific Institute of Oakland, CA, has researched this, and suggests that, in 2006:

1. Producing the bottles for American consumption required the equivalent of more than 17 million barrels of oil, not including the energy for transportation.

2. Bottling water produced more than 2.5 million tons of carbon dioxide.

3. It took 3 liters of water to produce 1 liter of bottled water

Thought-provoking, isn’t it? And there’s more. Check out the Pacific Institute fact sheet here.

And what did that bottle of water cost you? Let’s just say it’s a buck at the vending machine, and a quarter if you buy a 24-pack at the Big Box Store (BBS). The cost of water here at the Med Center is $0.0075 per gallon. Let’s see, 8 pints in a gallon…we’re at 0.09¢ (yes, about a 1/10th of a penny) per bottle, or roughly 275-16 oz. bottles for a quarter. The pint bottle of water from the BBS costs over 250 times more than tap water, and that doesn’t even take into account the environmental costs suggested by the Pacific Institute. And the vending machine bottle of water? Oh, my…almost 1,100 times the cost of tap water. The same tap water which, by the way, costs you nothing at work.

I looked up the cost of the 5-gallon jugs of water that get delivered to your home or office, and the per-gallon cost where I live is about $1.70, still 85 times the cost of that at the tap. I can look through the glass front door of the office next to ours and see at least six of these 5-gallon bottles are lined up in the reception area: I see opportunity, as I’ll explain.

The tide is starting, ever slowly, to turn against bottled water. A city in Vermont recently banned the sale of bottled water in less than one gallon sizes. It’ll be interesting to see how that goes. There are at least a couple of dozen colleges and universities in the US that have banned the sale of bottled water. One gets the sense that there is finally some pushback against bottled water.

What would you think about having access to a good, tasty alternative to bottled water here at work?  It makes sense that if you’re going to move away from bottled water (given the cost and the Hydration Stationenvironmental impacts of bottled water use, it’s a good thing to do), then there has to be a readily-available alternative. Most of the colleges mentioned above, and many who have not yet banned bottled water, have moved to hydration stations. These dispense filtered water from a shoulder-level spigot, making it easy to fill your reusable bottles. How many of you have tried to fill a bottle or other vessel from a drinking fountain with low pressure? Not a pretty sight.

Back to the hydration stations: I think we have a great opportunity to bring some in here at the Med Center and put forth a challenge to the bottled water system.  Most hydration stations are made to take the place of drinking fountains, and many feature both a bottle filling station and a drinking fountain, like the unit seen here (from one of many manufacturers of hydration stations).  I’ve seen units with a tally counter at the top, clicking over every 16 ounces dispensed to let you know the number of bottles of water for which purchase has been avoided.

While they have been well-received at colleges (and check them out the next time you’re at SFO), I would not expect hydration stations to replace bottled water sales at all locations at the Med Center. It’d be unreasonable to eliminate the option of a bottled water purchase for a visitor at the Main Hospital. However, I’d really like to see Hydration Stations take root in non-patient care areas. There’s a beat up drinking fountain outside of the EH&S office, and many 5-gallon bottled water users in the building. I bet we could swap out the drinking fountain for the hydration station, pay for that thing in two years, and provide some good environmental impact mitigation in the process.What do you think, FSSB? Shouldn’t we be in the lead here? Last thing we want is some other location, like Broadway or Medical Education to beat us out. I’m ready to get a trial started. It’s like a Race to the Top. Who’s going to have the first hydration station at UCDHS? Who wants to save money while protecting the environment? Standby…

    Good article, but I would like to see more recent statistics than 2006, that is seven years ago.

  • boiling

    Our heating element contains its own small electronic control unit so it’s easily replaced when it eventually does wear out. Everything else is recyclable. That means only 2% of our product ends up as landfill.

The Sustainability Imperative

Posted by JD on January 22nd, 2013 in Uncategorized | 91 comments »

Have you ever considered what it takes, in labor and resources, to give us the goods that we take for granted?  Are some items so resource and labor intensive that they take away from other things, perhaps essential, presenting us with an “either/or” situation?  Are we using so many resources now that our kids and grandkids will be hard pressed to have the same things that we enjoy?  Is that what we want, is it how we want to be remembered?  Perhaps it’s better to operate with sustainability in mind.

It’s instructive to Google (“Google” is a verb now, isn’t it?) “sustainability”, to read the various takes on the term and get a general idea of what it means.  In particular, what does it mean to you?  To some, sustainability is synonymous with recycling, for example; “I recycle, therefore I am sustainable”.  Well, it’s a place to start.  For others, part of being sustainable is buying organic foods, hence avoiding the use of petrochemical fertilizers and their impact on the environment.  Still others try to make sure that their activities are mindful of the environmental, avoiding air and water pollution.  Additionally, there are folks out there who feel that the concept of sustainability is a nefarious United Nations plot to erode our freedoms (Google “Agenda 21” for some fun reading).

Broadly put, “sustainability” is making sure we leave a usable Earth for our descendents.  One of the most widely quoted definitions, from the Brundtland Commission of the United Nations, reads as follows: “Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” To get our arms around this concept, let’s consider some of the things that we take for granted, and whether our current practices might jeopardize the ability of future generations to access these same things.

How about a piece of printer paper?  Have you ever thought about what goes into the production of that sheet of paper?  First, cut down some trees; there are other source materials, but let’s stick with trees.  Transport them to the mill, grind them up, apply chemicals in the Kraft process (converting wood into pulp/fibers), and apply more chemicals for the bleaching process.  Now the pulp is ready to be formed into sheets and dried, which takes a lot of processing and energy.  The paper ends up in large rolls, and leaves the paper mill to travel to a converter, where the paper is cut to size and packaged.  After some storage and transportation, then local handling, the sheet of paper is in your printer, ready for use.  It’s quite a process to go from tree to printer, involving a number of potential environmental impacts from the chemicals, and one can just imagine the amount of energy used.  It’s nice to know that it takes fewer chemicals and less power to convert used paper to new paper with “post consumer content”.  You are recycling waste paper, aren’t you?

Speaking of energy, let’s consider the lights in your work area.  All lights take some energy, with newer types of lamps using much less than older styles (but sometimes at higher cost).  Where does that energy come from?  At the Medical Center, it comes from our Central Energy Plant, where a jet engine, of the same type used in the old Lockheed L-1011, provides the motive power to turn a very large generator to make electricity.  The electricity travels through various wires, breakers, and transformers before it ends up at the switch that controls your lights.  Flip the switch to turn the lights on and the electricity travels through a few more wires to the ballast, then on to the fluorescent tube, where it excites mercury vapor (all fluorescent lamp have a tad of mercury), producing UV light which causes phosphors to fluoresce, providing visible light.  Also, way before you get this light, someone puts the complex wheels in motion to make natural gas available to operate the gas turbine in the Central Plant.

It’s interesting to think about the complexities that provide even the most common things in our lives.  Some people prefer to compartmentalize these realities in an “out-of-sight/out-of mind” manner, in the same way that they like to eat meat but don’t want to know how it got into the package at the market.  If you take a moment to consider the processes required to make paper or produce electricity, and acknowledge that all require a number of finite resources, you’ll see that a “business as usual” approach to life could make it harder for your grandkids to have paper to write on or light by which to see.

The Sustainability Imperative implores us to consider those things that make up our early 21st century lives, and asks us to consider what it will take to make these attributes available later in this century and beyond.  The earth’s population is growing, our resources are in decline, and technology won’t always be able to rescue us.  No one will conserve in your stead; it is up to each of us to take action.

When your unit’s Green Advocate reminds you to recycle, or turn off your task lights when you leave, remember the complex processes that bring form and function to our lives. It’s not just a piece of paper, it’s part of a process comprised of numerous inputs.  Leaving the lights on further burdens our dwindling resources.  Add a “sustainability” context to your decisionmaking.  Doing the right thing isn’t always the easy thing, but it’s always the best thing.

Do something GREEN today!

JD.

    It is amazing the damage human beings can cause by ignoring the issue of long term sustainability is their consumption, and opting for short term economic gain. The island of Haiti is a perfect example. Once two thirds covered by rainforests, it now has less than 2% of this resource left. Fortunately the Clinton Foundation is investing millions in endeavoring in an effort to reforest the island. Hopefully the effort will succeed.

    It’s crunch time. I am very much afraid that we have already passed the tipping point where the damage mankind has done to the planet is irreversibly sending us spiraling to our doom. Even though we are waking up to things a little bit here in the US, countries like India and China are devastating the planet while racing to modernize.

    On a more positive note, I had the incredible good fortune to visit the internationally recognized lighting research facility at UC Davis a few years ago while I was still working in the solar industry. Some of the things that I saw during that visit I am now seeing in the marketplace. It’s remarkable how rapidly the costs for LED lighting has come down and how fast that technology has improved. It won’t be long before it completely overtakes all other forms of lighting.
