Turning CO2 into plastic?

Interesting stuff…

Sifting the Garbage for a Green Polymer – New York Times

It was here that Dr. Coates discovered the catalyst needed to turn CO2 into a polymer.

With Scott Allen, a former graduate student, Dr. Coates has started a company called Novomer, which has partnered with several companies, including Kodak, on joint projects. Novomer has received money from the Department of Energy, New York State and the National Science Foundation. Dr. Coates imagines CO2 being diverted from factory emissions into an adjacent facility and turned into plastic.

Anthropogenic CO2 emissions = 7 Giga ton per year. So it will take a lot of plastics to take care of that. The promise of biopolymers is that they reduce the need for fossil fuels, and are biodegradable.

Seems to be another case where some funding and regulatory nudging away from the petroleum plastics would really help.

    Fish-Killing Virus Spreading in the Great Lakes – New York Times

    A virus that has already killed tens of thousands of fish in the eastern Great Lakes is spreading, scientists said, and now threatens almost two dozen aquatic species over a wide swath of the lakes and nearby waterways.

    The virus, a mutated pathogen not native to North America that causes hemorrhaging and organ failure, is not harmful to humans, even if they eat contaminated fish. But it is devastating to the ecosystem and so unfamiliar, experts said, that its full biological impact might not be clear for years. It is also having a significant impact on the lakes’ $4 billion fishing industry.

    There is no known treatment for the virus. As a result, scientists are focusing on managing its spread to uncontaminated water — quite a challenge since the Great Lakes are linked and fall under the jurisdiction of several states and provinces in Canada.

    North Carolina to establish birding trail

    This is good news, maybe just the ticket to reawaken my long dormant birdwatching predelictions. The money this brings in will doubtless fund the continued existence of wetlands and other endangered habitats.

    newsobserver.com | Beauty, bucks sought in bird trail

    SWANSBORO – With hundreds of colorful birds already visiting and calling Eastern North Carolina home, the state is encouraging bird lovers to bring their binoculars and billfolds to watch them. The N.C. Birding Trail unveiled this week links dozens of sites long known to birders as packed with rare, popular or threatened species, such as the endangered red-cockaded woodpecker.

    But state officials are promoting the trail as nature-themed tourism and hope it will give the financially stressed region an economic boost.Forget the notion of birdwatching as a sedate, nerdy activity. Now hunting and fishing guides are running bird charters and bird-related tourism is worth millions.

    “We have people coming here from all over the country,” said John Ennis of Brunswick County, eastern vice president of the Carolina Bird Club. “It’s a great resource.”

    When completed, the North Carolina trail will include dozens of places across the state that visitors can reach by car and look for more than 440 species of birds.

    The first section, which highlights the coastal region, includes 102 birding sites in 16 groupings east of Interstate 95. A Piedmont trail that will bundle sites between Interstate 95 and Interstate 77 is scheduled to be completed next year with a mountain trail slated after that.

    At least 100 sites have already been approved for the Piedmont section with three dozen in the Triangle. Birders will be directed to state and local lands such as Hemlock Bluffs Nature Preserve in Cary, Raleigh’s Lake Johnson Park, Eno River State Park in Orange County and Duke Forest in Durham County.

    Salinda Daley, N.C. Birding Trail Coordinator, said that describing the program as a trail causes some misunderstanding because it is not just lines on a map. She said promotional material links spectacular bird watching sites and birders with communities and businesses.

    hey, who’re you calling a nerd!!

  • Rolling Stone Magazine Expose' on the Pork Industry

    Excellent article, read in full, and let the next mass market pig you eat weigh on your conscience a little bit.

    I have attended meetings organized by the North Carolina Environmental Justice Network recently, and Smithfield foods is high on their agenda for the mind blowing pollution that overwhelmingly affects the poor and rural African-American communities, for their appalling safety record, and early American style treatment of its workers. See this PBS video for more. It is truly heartbreaking to hear testimony from people who live near hog farms, how the stench is overwhelming, omnipresent, and travels in your clothes and system wherever you go.

    Some Excerpts:

    Rolling Stone : Pork’s Dirty Secret: The nation’s top hog producer is also one of America’s worst polluters

    Smithfield Foods, the largest and most profitable pork processor in the world, killed 27 million hogs last year. That’s a number worth considering. A slaughter-weight hog is fifty percent heavier than a person. The logistical challenge of processing that many pigs each year is roughly equivalent to butchering and boxing the entire human populations of New York, Los Angeles, Chicago, Houston, Philadelphia, Phoenix, San Antonio, San Diego, Dallas, San Jose, Detroit, Indianapolis, Jacksonville, San Francisco, Columbus, Austin, Memphis, Baltimore, Fort Worth, Charlotte, El Paso, Milwaukee, Seattle, Boston, Denver, Louisville, Washington, D.C., Nashville, Las Vegas, Portland, Oklahoma City and Tucson.

    To appreciate what this agglomeration of hog production does to the people who live near it, you have to appreciate the smell of industrial-strength pig shit. The ascending stench can nauseate pilots at 3,000 feet. On the day we fly over Smithfield’s operation there is little wind to stir up the lagoons or carry the stink, and the region’s current drought means that lagoon operators aren’t spraying very frequently. It is the best of times. We can smell the farms from the air, but while the smell is foul it is intermittent and not particularly strong.Unsurprisingly, prolonged exposure to hog-factory stench makes the smell extremely hard to get off. Hog factory workers stink up every store they walk into. I run into a few local guys who had made the mistake of accepting jobs in hog houses, and they tell me that you just have to wait the smell out: You’ll eventually grow new hair and skin. If you work in a Smithfield hog house for a year and then quit, you might stink for the next three months.

    Epidemiological studies show that those who live near hog lagoons suffer from abnormally high levels of depression, tension, anger, fatigue and confusion. “We are used to farm odors,” says one local farmer. “These are not farm odors.” Sometimes the stink literally knocks people down: They walk out of the house to get something in the yard and become so nauseous they collapse. When they retain consciousness, they crawl back into the house.

    Successful Farming magazine warned — six years ago. There simply is no regulatory solution to the millions of tons of searingly fetid, toxic effluvium that industrial hog farms discharge and aerosolize on a daily basis. Smithfield alone has sixteen operations in twelve states. Fixing the problem completely would bankrupt the company. According to Dr. Michael Mallin, a marine scientist at the University of North Carolina at Wilmington who has researched the effects of corporate farming on water quality, the volumes of concentrated pig waste produced by industrial hog farms are plainly not containable in small areas. The land, he says, “just can’t absorb everything that comes out of the barns.” From the moment that Smithfield attained its current size, its waste-disposal problem became conventionally insoluble.

    Nice, huh! Still eating factory pork?

    Virus Implicated In Colony Collapse Disorder In Bees

    This is a potentially important find, but as usual, I feel the need to stress that at this point in time, as the scientists did too, that they correlated the presence of this virus with the prevalence of Colony Collapse Disorder. It is likely that this virus, while being a contributing factor, is not the only cause. Other contributors may include stress, the fact that these bee hives are transported thousands of miles, etc.

    But, great detective work by this collaborative team of academics, American government scientists and one for-profit company.

    ScienceDaily: Virus Implicated In Colony Collapse Disorder In Bees

    A team led by scientists from the Columbia University Mailman School of Public Health, Pennsylvania State University, the USDA Agricultural Research Service, University of Arizona, and 454 Life Sciences has found a significant connection between the Israeli Acute Paralysis Virus (IAPV) and colony collapse disorder (CCD) in honey bees.

    The findings, an important step in addressing the disorder that is decimating bee colonies across the country, are published in the journal Science.

    In colony collapse disorder, honey bee colonies inexplicably lose all of their worker bees. CCD has resulted in a loss of 50-90% of colonies in beekeeping operations across the U.S.

    I was just thinking I should check on the progress of scientists towards finding a cause for this issue, seems like I did not have to!

    Water Find to End Darfur War – Well, not so fast!

    Beware the dangers of the overhyped press release machine (or sciencedaily, pick your poison). All Farouk El-Baz saw when he did the radar study was a giant depression. It is TBD whether there’s water in them thar holes!’

    BBC NEWS | Africa | Ancient Darfur lake is dried up

    Alain Gachet, who used satellite images and radar in his research, said the area received too little rain and had the wrong rock types for water storage. But the French geologist said there was enough water elsewhere in Darfur to end the fighting and rebuild the economy.

    On Wednesday, Boston Universitys Farouk El-Baz said he had received the backing of Sudans government to begin drilling for water in the newly-discovered lake, in North Darfur.

    No wonder they say that water is the 21st century oil. This guy’s going to be drilling for water (also known as well digging!).

  • Pesticide Screening Using a CD Player and CDs.

    Who said CDs were dead, this is, hands down, the coolest paper on screening techniques I have seen in a while. I haven’t seen the rest of the paper, not Open Access, of course, but the abstract does make it sound cool.

    Microimmunoanalysis on Standard Compact Discs To Determine Low Abundant Compounds

    “High-density competitive indirect microimmunoassays were performed in both sides of compact discs by direct absorption of immunoreagents on polycarbonate surface, using gold- or enzyme-labeled immunoglobulins as tracers for displaying the immunoreaction. The operational principle is based on the use of a low-reflectivity compact disc as analytical platform that allows the reflection/transmission (30/70%) of the CD reader laser beam ( 780 nm). The reflected light is used to scan the disc track keeping it in movement. The transmitted light is detected by a planar photodiode integrated on the CD drive. The variation of the optical transmission of the light caused by the immunoreaction products is related to the sample concentration. As a proof of concept, low abundant compounds, commonly used as pesticides, were detected in a 60-min total assay time, with a limit of detection ranging from 0.02 to 0.62 ug/L for 2,4,5-TP, chlorpyriphos, and metolachlor. The obtained results show the enormous prospective of compact discs in combination with CD players for multiresidue and drug discovery applications.”

    Why are techniques like these important in the world of environmental analysis? Because they change the paradigm from laboratory based techniques to field based analysis. You don’t have to take a bunch of samples, spend a lot of time and money shipping them to a lab and waiting for the results. You can pop your samples into a CD player and one hour later (less than a 74 minute listening time on a CD!), you’ll have results.

    Awesome stuff, I’d love to see it in action, or even try to replicate the work. It looks like you have to make some modifications to the player to make it work, but hey, there are millions of CD players that are going to be obsoleted in the next few years.
