Recycling better than landfilling even to China

Byoliveridley

Sending old newspapers and plastic bottles 10,000 miles for recycling in China produces more carbon savings than landfilling it in Britain and making new goods, reveals a study from the government body charged with reducing UK waste.In the last 10 years annual exports of paper, mainly to India, China and Indonesia, have risen from 470,000 tonnes to 4.7m tonnes, while exports of old plastic bottles have gone from under 40,000 tonnes to half a million tonnes.Now the counterintuitive conclusions of the report from the Waste Resources Action Programme (Wrap) suggest that the advantage of recycling over landfilling is so great that it makes environmental sense to ship waste right round the world if it can be used again.

One of the issues with carbon footprint calculations like these is that they are very dependent on the assumptions made and the calculations used. So, without going through the study line by line, I don’t know if this is true or not, but it is good to know that sending recycling waste many thousands of miles at least does not result in increased resource use. However, the environmental justice implications are still weighted against the receiving country, especially in the recycling of toxic electronic waste. This particular study only dealt with plastic and paper, so the toxic implications were fewer.

Of course, reducing the stuff you use and reusing your stuff always beats recycling, oh ye iphone lusters, let your old phone die first!

    Tuesdays with Turtles – Climate change and nesting patterns

    Byoliveridley

    Turns out that in Guyana, nesting patterns are changing. Different types of sea turtles are showing up, and earlier than they used to. The earlier part can be explained by climate change, but the species distribution? I am sure there are other factors involved including habitat loss, poaching, etc. Anyway, interesting story.

    Stabroek News

    The changing nesting patterns of endangered sea turtles in Guyana, is alerting environmentalists to the impact of climate change on these marine animals.

    The shell beaches in Region One have hosted thousands of nesting turtles over the years, and conservationists have been endeavouring to protect the turtles from heavy domestic use and from being traded.

    Project Coordinator of the Guyana Marine Turtle Conservation Society (GMTCS) Michelle Kalamandeen told Stabroek News recently that climate change is affecting the sea turtle population.

    According to Kalamandeen, in the 1960s the Hawksbill (critically endangered) and the Olive-Ridley (endangered) were our main nesting turtles, now the green turtles (endangered) and the leatherbacks (critically endangered) are mostly coming to nest on Guyana’s shores. The Pacific Leatherback is said to be now extinct and the Atlantic Leatherback is facing extinction.

    The change in the time period for nesting in Guyana, she said, may also be a significant sign.

    Usually sea turtles nest in Guyana from March to August every year. However, for the last three to four years, says Kalamandeen, the nesting pattern has shifted from mid-January to mid-July. This may have a significant impact on the hatchlings as food availability may be an issue for them.

  • The Onion on Conservation

    Byoliveridley

    This is so sad, though there is more than a kernel of truth to it. Individual efforts mostly make people feel better about themselves (hey, I recycle, makes me feel good!). It is the Onion and it does go too far. Of course individual efforts add up, and more importantly, force the important players like government and big industry to modify their behavior just a little bit (at least that is what I tell myself).

    I’m Doing My Inconsequential Part For The Environment | The Onion – America’s Finest News Source

    Every day, without fail, I meticulously organize my recyclables into five distinct categories, thereby subtracting an eyedropper’s worth of garbage from the countless tons of waste that ferment in our landfills. It only takes a few extra minutes, but just think of the impact it totally lacks. I also refuse to use anything but “Earth-friendly” paper products—some of which contain up to 10 percent recycled materials. For me, it’s worth shouldering the extra cost, but, unfortunately, only a scant few of us bother to do the same. And growing some of my own organic vegetables in my backyard garden also, to my immense gratification, reduces the use of toxic chemical-based pesticides and herbicides present in corporate farming techniques by as much as 0.0000000000000000000000000000000000000001 percent.

    Arsenic in the News

    Byoliveridley

    Professor wins $1M for arsenic filter – Yahoo! News

    The National Academy of Engineering announced Thursday that the 2007 Grainger Challenge Prize for Sustainability would go to Abul Hussam, a chemistry professor at George Mason University in Fairfax. Hussam’s invention is already in use today, preventing serious health problems in residents of the professor’s native Bangladesh.

    This British Geological Survey website provides a good primer to the problem. Some key points:

    1. Arsenic is very toxic
    2. Arsenic is naturally occurring in the shallow groundwater aquifers of Bengal and Bangladesh at a toxic level
    3. The surface water is contaminated with bacteria and was responsible for high infant mortality, so aid agencies in the ’70s encouraged the use of tube wells and other groundwater pumps. While this contributed to a decline in infant mortality from gastrointestinal infections, it also dosed unsuspecting people with disease causing levels of arsenic
    4. The technology for removal of arsenic is very well known. But most solutions require electricity/periodic maintenance/technical skills and are thus not universal or sustainable.
    5. Simplicity is the key. You can’t tell the people to not drink the water, it is the only clean water available. You can’t install water treatment plants, there is no running water, you can’t rely on solutions that are centralized.

    So with all that in mind, here’s what Prof. Hussam did:

    The Gold Award-winning SONO filter is a point-of-use method for removing arsenic from drinking water.  A top bucket is filled with locally available coarse river sand and a composite iron matrix (CIM).  The sand filters coarse particles and imparts mechanical stability, while the CIM removes inorganic arsenic.  The water then flows into a second bucket where it again filters through coarse river sand, then wood charcoal to remove organics, and finally through fine river sand and wet brick chips to remove fine particles and stabilize water flow.  The SONO filter is now manufactured and used in Bangladesh. That’s great, and easy!

    That’s pretty much freshman chemistry right there, further proof that most innovation does not need new science, only people willing to spend some time on problems that don’t necessarily get looked at.

  • Nuclear Energy not Carbon Free?

    Byoliveridley

    Who would have thunk it, turns out that uranium mining and nuclear waste storage result in significant carbon emissions…
    New Debate Over Nuclear Option

    Now, some scientists and other experts are beginning to raise a different question about nuclear power: Is it really as clean as supporters contend? A report, released on Mar. 26 by a British nongovernmental organization called the Oxford Research Group, disputes the popular perception that nuclear is a clean energy source. It argues that while nuclear plants may not generate carbon dioxide while they operate, the other steps necessary to produce nuclear power, including the mining of uranium and the storing of waste, result in substantial amounts of carbon dioxide pollution. “As this report shows, hopes for the climate-protecting potential of nuclear energy are entirely misplaced,” says Jürgen Trittin, a former minister of the environment in Germany and a contributor to the report. “Nuclear power cannot be promoted on environmental grounds.”

    The report, called “Secure Energy? Civil Nuclear Power, Security and Global Warming,” examines a number of risks from nuclear power development, including concerns over the disposal of radioactive waste and the threats from terrorist groups. But its most novel component may be the quantitative examination of carbon emissions on a comprehensive basis. “Carbon emissions are a global problem and it’s time to look at the carbon released by nuclear power globally,” says Jan Willem Storm van Leeuwen, author of the report’s chapter on carbon emissions. “The assumption has long been that the [greenhouse] effect is zero, but the evidence shows otherwise.”

    carbonfacts_sm.jpg“Novel component”?, well, I would not go that far, it appears that the authors performed a carbon footprint analysis and concluded that the carbon footprint of nuclear fission energy production was somewhere between renewables and fossil fuel power generation, which is not entirely surprising. Coupled with all the other issues facing nuclear energy, and the obvious environmental justice issues that impact the siting of any new plant or waste repository, nuclear energy should not be a very serious option at all. Unfortunately, it’s a great boondongle for the developers of the plants because the subsidies and power pricing mechanisms ensure profits for the developer at the expense of the general public, and waste disposal issues can forever be postponed, eventually leaving governments (and tax payers) to pick up the tab.

    By the way, go read Jamais Cascio’s interesting post about the carbon footprint of a cheeseburger. The “nutrition like label” shown here is something I wish to see in almost every product used! It would make the regulation of carbon a lot less complicated. It appears that England will take the lead on this concept, see Carbon Labelling (yes, 2 L’s, the “correct” spelling!).

  • On writing

    Byoliveridley

    Sometimes, you have to read what you’ve written in order to keep writing. I have not felt like writing at all, except in 140 character snippets. There are lots of people saying lots of things all the time, so who really cares, right? But I came back and read a post or two I had written on this blog, they weren’t half bad.

    Consider myself a little more encouraged, I shall write more, soon, no pressure 🙂
