Where Have the Plastic Bags Gone?

Plastic bags are everywhere. Many years ago the only bags at the grocery store were paper ones. Now you have a choice of paper, plastic or bring your bag. Where have all the bags gone after they are used? Plastic bag and film recycling in the U.S. reached a record high in 2008, recovering about 832 million pounds of post consumer film, according to a new study from the American Chemistry Council.

Plastic bags are difficult and costly to recycle and many end up on landfill sites where they take around 300 years to photo degrade. They break down into tiny toxic particles that contaminate the soil and waterways and enter the food chain when animals accidentally ingest them. But the problems surrounding waste plastic bags starts long before they photo degrade. Many become airborne and float surprising distances. Others can choke waterways and animals.

The “National Post-Consumer Recycled Plastic Bags and Film Report,” conducted by Moore Recycling Associates, finds that plastic bag and film recovery increased 28 percent since 2005, driven by several factors including greater consumer access to collection programs and new markets for the recycled materials such as backyard decking, fencing, railings, shopping carts and new bags.

As China’s Pollution Toll Grows, Protesters and Media Push Back

written by Yale Environment 360

In recent months, protests over the severe illnesses caused by China’s heavy industries have resulted in a crackdown on polluters. Leading the charge has been the state-run media, which the central government is now using to gain control over corrupt local authorities and powerful commercial enterprises.

Last August, residents of Chongqing town in the central Chinese province of Shaanxi surrounded the town’s huge lead works, run by China’s largest lead smelting company. It was a brave act in a totalitarian country. But the people of Chongqing were angry because the town’s doctors had found that of the 731 children they checked, 615 were suffering from lead poisoning caused by pollution from the Dongling Lead and Zinc Smelting Company.

Swedish Entrepreneur Dreams Up Disposable Toilet

written by Walter Wang

According to the United Nations, an estimated 40 percent of the global population, or close to 2.6 billion million people do not have access to a toilet of any sort, even a pit latrine.

This has created a public health crisis in developing countries, both in terms of contaminated drinking water and poor sanitation techniques. More than one million children mostly under the age of five die each year from diarrhea resulting from this lack of sanitary conditions. While the technology exists to solve this problem, it is expensive and sometimes hard to install.

But Swedish architect and entrepreneur, Anders Wilhelmson is hoping to tackle the issue with his invention: a safe, affordable, biodegradable plastic bag called the Peepoo that can be used as a single-use toilet.

New Study Tracks ‘Outsourcing’ of Greenhouse Gas Emissions

written by Yale Environment 360

More than one-third of the carbon dioxide emissions associated with consumer goods used in developed nations is actually emitted in other nations where the products are made, according to a new study.

In the United States, about 2.5 tons of carbon produced per person annually — or about 11 percent of U.S. per capita emissions — are emitted elsewhere, researchers at the Carnegie Institution for Science say.

In Europe, it’s about four tons of carbon per person. In fact, in smaller European nations like Switzerland, the emissions associated with products manufactured outside the borders exceed the actual emissions produced at home.

China Says It Will Move to Enforce Greenhouse Gas Goals

written by Walter Wang

BEIJING (Reuters) – China said on Sunday it will spell out greenhouse gas emissions goals and monitoring rules for regions and sectors in its next five-year plan, with monitoring to show it is serious about curbing emissions.

The Chinese government said in November it would reduce the amount of carbon dioxide, the main greenhouse gas from human activity, emitted to make each unit of national income by 40 to 45 percent by 2020, compared with 2005 levels.

That goal would let China’s greenhouse gas emissions keep rising, but more slowly than its rapid economic growth.

The policy was a cornerstone of Beijing’s position at the Copenhagen summit on climate change late last year when governments tried with limited success to agree on a new global treaty on fighting global warming.

The United States and other powers said China, the world’s biggest emitter of greenhouse gases from industry and other human activities, should have offered to do more to bring its domestic “carbon intensity” goal into an international pact that would reassure other governments.

Closing Hole in Ozone Layer to Increase Global Warming?

written by Environmental News Network

The U.S. Environmental Protection Agency recently proposed new ozone standards to protect health and environmental values. These standards will apply to the lower atmosphere, to the air we breathe. In the upper atmosphere, ozone is good.

The “hole” in the ozone layer over Antarctica has worried scientists for years since ozone in the upper atmosphere protects the Earth from harmful ultraviolet radiation from the Sun.

According to research at the University of Leeds, the hole in the ozone layer is now steadily closing. This is a concern, since its repair could actually increase warming in the southern hemisphere, the scientists at Leeds conclude.

Ozone Pollution From Asia Blown to North America

written by Environmental News Network

Ever wonder how the western US has high ozone levels when the winds usually blow in off the Pacific Ocean? Did you think it was all from the cars clogging the freeways? Turns out, it is caused in part from emissions of ozone generating air pollutants from Asia.

A study by the National Oceanic and Atmospheric Administration (NOAA) shows that Springtime ozone levels above western North America are rising, primarily due to air flowing eastward from the Pacific Ocean, a trend that is most significant when the air originates in Asia. These increases in ozone could make it more difficult for the United States to meet Clean Air Act standards for ozone pollution at ground level, according to a new international study published online Jan. 20 in the journal Nature.

Salazar: Bush Offered Oil and Gas Industry Candy Store

written by Yale Environment 360

U.S. Interior Secretary Ken Salazar said his department will no longer be the “handmaiden” of the oil and gas industry and will conduct tougher environmental reviews of proposals to drill on public lands. Criticizing the Bush and administration for turning federal lands into a “candy store” for the petroleum industry, Salazar told reporters, “The difference is in the prior administration the oil and gas industry essentially were the kings of the world.” He said lax leasing policies “ran afoul of communities, carved up the landscape, and fueled costly conflicts that created uncertainty for investors and industry.”

Salazar said he was ordering federal land managers to get out from behind their desks and to visit proposed leasing sites to evaluate the environmental and social impacts of drilling. The stricter review process would not reduce the amount of oil and gas extracted from federal lands, Salazar said, but would ensure that drilling was done in a more responsible manner.

Green Chemistry: Underused Drilling Practices Could Avoid Pollution

written by Walter Wang

As environmental concerns threaten to derail natural gas drilling projects across the country, the energy industry has developed innovative ways to make it easier to exploit the nation’s reserves without polluting air and drinking water.

Energy companies have figured out how to drill wells with fewer toxic chemicals, enclose wastewater so it can’t contaminate streams and groundwater, and sharply curb emissions from everything from truck traffic to leaky gas well valves. Some of their techniques also make good business sense because they boost productivity and ultimately save the industry money — $10,000 per well in some cases.
