Recycling Paper

recycle.gifNow you’re having this conversation over dinner about recycling (yes, I have had this conversation before with lots of people), and there pipes up this voice which says “Well, I read somewhere that it costs more money to recycle than to just throw it away”, and you think, “waitaminnit, that can’t be right, but where’s the proof?” Well, at least for paper, here it is, and bless the EU for taking the trouble (I read about this in the Environmental Valuation and Cost-Benefit News Blog).

Lifecycle Analysis and Cost Benefit Analysis on Paper Recycling

No, I did not read all 160 pages, but sure did read the Executive Summary…

The LCA review concludes that the majority of LCAs indicate that recycling of paper has lower environmental impacts than the alternative options of landfill and incineration. The result is very clear in the comparison of recycling with landfilling, and less pronounced, but still clear, in the comparison of recycling with incineration. The CBA review concludes that in little more than half of the CBAs, paper recycling has higher socioeconomic benefits than other management options. In the remainder of the studies, the socio-economic benefits of incineration, landfill or other options are higher than those gained from recycling. It is often said that CBAs are generally favourable to other waste management options than recycling. However due to the heterogeneity of the methodologies used in the reviewed CBAs, it is not possible to confirm or to reject this statement.

They looked at 9 different regions and did an LCA and CBA for each. Apparently, and I did not know this, the LCA evaluation system is well standardized and codified, so it is easy to compare results between regions, but the CBA mechanisms are not as well codified, hence more sensitive to the assumptions made.

Fascinating reading aside, the answer is clear, recycle your paper! At least they make it easy in Chapel Hill.

    The Pump handle and Diacetyl

    The Pump Handle looks at the response of various government agencies (notionally charged with protecting American people) to increasing information about the danger of diacetyl exposure, certainly to workers in the flavoring industry, and recently, to consumers of microwave popcorn. An excellent post, deserves wider reading!


    Popcorn Lung Coming to Your Kitchen? The FDA Doesn’t Want to Know « The Pump Handle

    The CDC, FDA, OSHA, EPA – federal agencies charged with protecting public health – each received a letter in July alerting them to the possible serious respiratory hazard to consumers who breathe in fumes from their artificially butter-flavored microwave popcorn. The warning should have resulted in some action by these agencies, but instead, they’ve done virtually nothing.

    It appears that the Bush Administration’s efforts to destroy the regulatory system are succeeding; the agencies seem unable to mount a response to information that a well-functioning regulatory system would immediately pursue. The agencies aren’t even trying to connect the dots.

    Read on. I moved to the US in 1997 and I’ve noticed a stark difference in the performance of the government agencies named here. I have no doubt that the agencies will eventually bounce back under the right circumstances, but it is disheartening how far agencies such as the EPA, once regarded as models of well run government (at least to a developing country!) have fallen.

  • What happens when…

    the national science academies of the 13 most important countries release a landmark strong statement about the state of the world’s energy crisis? According to the grist, nobody listens. Well, here’s to my 10 or so readers (self deprecation is the best deprecation!), the rant!

    Bad news re: good news about bad news | Gristmill: The environmental news blog | Grist

    The bad news is that we are in quite a pickle.

    The good news about the bad news is that the national science academies of the G8 countries, along with those of Mexico, Brazil, South Africa, China, and India, have issued a unanimous and remarkably strong statement about our global energy quandary.

    The bad news about the good news about the bad news is that the press is almost totally silent about it, at least in English-speaking countries.

    Among the crucial statements in this document (PDF):

    • “Our present energy course is not sustainable.”
    • “Responding to this demand while minimizing further climate change will need all the determination and ingenuity we can muster.”
    • “The problem is not yet insoluble but becomes more difficult with each passing day.”
    • “G8 countries bear a special responsibility for the current high level of energy consumption and the associated climate change. Newly industrialized countries will share this responsibility in the future.”

    Let me be as polite as I can stand about this. Where in the @$#! is the press?

    And it goes on in similar vein…

    If you read the pdf, you will note that it has the obvious solutions (obvious to the half alive, that is)

    1. Set standards and promote economic instruments for efficiency, and commit to promoting energy efficiency for buildings, devices, motors, transportation systems and in the energy sector itself.
    2. Promote understanding of climate and energy issues and encourage necessary behavioural changes within
      our societies.
    3. Define and implement measures to reduce global deforestation.
    4. Strengthen economic and technological exchange with developing countries, in order to leapfrog to cleaner and more efficient modern technologies.
    5. Invest strongly in science and technology related to energy efficiency, zero-carbon energy resources and carbon-removing technologies.

    Nothing new here, just a very easy policy framework under which every major action taken by every one of these countries (and others) needs to work. Of course, planning, evaluation, implementation, etc. are difficult, especially on the technology transfer, behavioral change, and deforestation, but evaluate every major decision under this framework. You will see that things like corn ethanol (promotes deforestation, carbon intensive, not energy efficient), coal to liquid technology (carbon intensive, polluting, inhibits behavioral change), suburban sprawl (energy inefficient, inhibits behavioral change, etc.), excessive patent protection and intellectual property rights (inhibits technology transfer), war (well, everything on the list, really!), and I can keep going on, are just plain stupid, irresponsible and will lead the world to ruin.

    just print that framework out (or better still, put it in your PDA) and evaluate every thing you read about energy policy using it. You’ll see why I beat my head against the wall a lot!

    Also, note this simple two sentence evisceration of the “China and India are not doing it, so we won’t” argument…

    G8 countries bear a special responsibility for the current high level of energy consumption and the associated climate change. Newly industrialized countries will share this responsibility in the future

    I would add, of course, that G8 countries bear both current, and historical responsibility, other than that, well said.

  • Coal Fired Power Plants – Moratorium needed

    Cleaner Coal Is Attracting Some Doubts – New York Times

    Within the next few years, power companies are planning to build about 150 coal plants to meet growing electricity demands. Despite expectations that global warming rules are coming, almost none of the plants will be built to capture the thousands of tons of carbon dioxide that burning coal spews into the atmosphere.

    This is batshit insane and irresponsible. The US of A does not have a carbon policy (other than use as much as you possibly can!), and, only in the last few months have phrases like cap and trade and carbon taxes been used in respectable society. I am not going to get into the policy solutions here, there are much better discussions going on elsewhere.

    My question is this. When you know that 150 coal fired power plants are going to have a significant effect on the carbon emissions, how can you even think of approving them unless you have a carbon emissions mitigation policy in place already? If you let them be built, they will somehow grandfather themselves out of the controls. The power of existence is a big deal. Will anyone dismantle one of these once they’re operational? Think of the children!!

    There needs to be a moratorium on any large new power plants and other global warming sources until this country has figured out what emission targets it’s going to meet, how it’s going to meet them, and when it is going to meet them. Only then can the market decide which choices are feasible and which ones just don’t make sense. How will I know whether gasification or conventional burning/sequestration is better unless I have the metrics to measure them by? Depending on the emission reduction targets, they could both be economically viable, or neither.

    Something tells me that the word “moratorium” and the phrase “coal fired power plant” will never be uttered in the same sentence.

  • Benzene in Soft Drinks – Analytical Artifact?

    An update on the benzene story from last month.

    Chemical & Engineering News: Latest News – Dispute Over Benzene In Drinks

    In late 2005, FDA began analyzing beverages containing benzoate and ascorbic acid. The majority of samples contained either no detectable benzene or levels below 5 ppb, says Robert E. Brackett, director of FDA’s Center for Food Safety & Applied Nutrition. FDA’s results are preliminary. After its survey is complete, the agency will determine what, if any, additional action is necessary, Brackett wrote to EWG. Changes in FDA’s analytical procedures may account for the differences in results. To collect benzene in the earlier tests, FDA used a purge-and-trap method, in which the samples were heated to 100 °C for 30 minutes. Recently, the agency has been using a static-headspace methodology, which does not involve much heat. In the earlier tests, the high heat was probably creating benzene, says an FDA source who asked not to be identified.

    The explanation seems to make sense. Low level analysis is riddled with instances such as these, where the analyte you’re looking for is  introduced into the sample after the fact. It is impossible to decide without looking at the protocol whether this happened or not. Since the source of the benzene is from the reaction of ascorbic acid (aka Vitamin C) and benzoate salts, notably sodium benzoate, it would have been clear to anyone doing the analysis to avoid conditions that would result in the formation of benzene during the analysis, or maybe not…

    Static Headspace analysis usually involves some heating as well, at much lower temperatures for shorter periods of time, though in the case of something as hydrophobic as benzene, not much heat would be required. So, the artifacts in static headspace would in this case be lower than in purge and trap analysis.

    Still not a concern in the grand scheme of aggregate benzene exposure.

  • Liquid Coal – Temporarily Frozen

    Liquid coal is back in the news (at least my news!). Via the excellent Grist, Jon Tester (D-Montana – think coal!) casts a principled vote to kill an amendment that would have “mandated” a certain amount of liquid coal be used as part of an omnibus energy package bill.

    Panel rejects coal amendment

    Thomas accused Tester and other Democrats of failing to act on their words of praise for transportation fuels made from coal. But Tester said he couldn’t support the amendment because it would have scuttled the entire bill to which it was attached.

    Tester voted against the provision during a meeting of the Senate Energy and Natural Resources Committee to assemble an energy package. The legislation contains measures boosting biofuels, energy efficiency and research and development on carbon capture and storage technology.

    Thomas’s amendment would have required 21 billion gallons of coal-based fuels to be used annually by 2022. The bill already had a provision mandating 36 billion gallons of biofuels by 2022. The amendment was defeated on a 12-11 party-line vote.

    The Democratic and Republican heads of the Energy Committee had tried to prevent the coal-to-liquids issue from coming up during the panel’s meeting. They wanted to pass a bill out of committee easily and deal with contentious issues, including that one, during debate on the Senate floor

    With such powerful friends, this amendment will not go away. Expect it to be brought back on to the senate floor when it leaves committee. The coal senators of Illinois, West Virginia, Kentucky and the mountain west love the money this will bring to their states. They can pretend to look away from all the devastating effects of coal mining, and the CO2 emissions, etc. by invoking “energy security”. I give you senator Craig Thomas (R-Coal):

    “The bill we’re talking about of course does not include coal and the new opportunities to change the process for developing coal, which would not only enhance our security but it would also reduce and help with the global warming situation,” Thomas said. “I really think if we don’t deal with one of our most abundant resources then we fail to deal with energy security.”

    Yes, using liquid coal will “reduce and help with the global warming situation”. I mean, can’t you at least come up with a plausible half-truth?

    Liquid coal produces more CO2 than gasoline, so how will it help with the global warming situation? Seriously…

    March Babies not so Bright? – Pesticides to Blame?

    An Indiana scientist makes a rather provocative argument that exposure to pesticides in the womb can explain why Indiana babies conceived in July-August (Born March and April?) have lower achievement scores than the other kids.

    ScienceDaily: Conception Date Affects Babys Future Academic Achievement

    Dr. Winchester and colleagues linked the scores of the students in grades 3 through 10 who took the Indiana Statewide Testing for Educational Progress (ISTEP) examination with the month in which each student had been conceived. The researchers found that ISTEP scores for math and language were distinctly seasonal with the lowest scores received by children who had been conceived in June through August.

    “The fetal brain begins developing soon after conception. The pesticides we use to control pests in fields and our homes and the nitrates we use to fertilize crops and even our lawns are at their highest level in the summer,” said Dr. Winchester, who also directs Newborn Intensive Care Services at St. Francis Hospital in Indianapolis.

    “Exposure to pesticides and nitrates can alter the hormonal milieu of the pregnant mother and the developing fetal brain,” said Dr. Winchester. “While our findings do not represent absolute proof that pesticides and nitrates contribute to lower ISTEP scores, they strongly support such a hypothesis.”

    Well, that is a bold leap of faith, and use of a correlation=causation argument that I don’t appreciate in most cases. Has this kind of work been done in other countries, or in urban environments without pesticide use?

    I am sure that many chemicals have subtle, but significant effects on developing fetuses. And the chemicals the authors mention have links with hypothyroidism..

    Nitrates and pesticides are known to cause maternal hypothyroidism and lower maternal thyroid in pregnancy is associated with lower cognitive scores in offspring.

    There is a link, but without further data, I think the conclusions are a stretch. But, something to keep in mind I guess if you live in Indiana and want to plan a baby!

    Disclaimer: I was conceived in June, and was in the upper echelons of achievement through school. So, by the power of personal experience, I am predisposed to scepticism. OTH, I grew up in a big city with consistently high pollution levels throughout the year and not much pesticide exposure.
