Silicon Valley Toxics Coalition (SVTC) representative Dustin Mulvaney, an Assistant Professor at San Jose State University, works with SVTC to see that materials in computers and solar panels are safely handled and recycled. Mulvaney said First Solar is required to handle PV modules in a way that minimizes any accidental cadmium leakage at other sites. Most likely, he added, the biggest occupational hazard First Solar has encountered on the AVSR1 site is “workers being cut by broken glass.”

For 2011 Switzer Fellow Jeannette Laramee, it all started with designing a school in Zambia, Africa. That led to building systems that make biogas, which can save up to 10,000 pounds of firewood a year for a family in Africa.

After compiling data from 21 Silicon Valley companies, Wilson and his co-authors Heather Madison and Steven Healy discovered that 57 percent of the companies surveyed did not have a confined space safety plan in place other than to call the fire department. As a result, the companies resort to calling 911 in the case of any confined space emergency. “The employers need to take responsibility for having a way to rescue their employees in the event of a confined space emergency before the firefighters arrive,” Wilson said.

Several studies have implicated lead poisoning in deaths of the endangered California condor. A study published this year found lead poisoning was the primary cause of death in juvenile and adult condors from 1992 to 2009. A 2010 study analyzed three to four months of lead levels using condor feathers and found much higher and more frequent exposures than blood draws suggested, said Myra Finkelstein, an environmental toxicologist at UC Santa Cruz, who conducted the study. Still other work tied the chemical composition of lead found in poisoned birds with that of ammunition.

The Northeast Recycling Council Inc. (NERC), based in Brattleboro, Vt., has adopted a policy position in opposition to the use of degradable additives in plastic packaging. “The board determined that this practice currently has a negative impact on plastics recycling markets and the effectiveness of plastics recycling in general,” reports Sarah Kite, president of the NERC board.

What will cost $7 billion; will snake across the country from Alberta to the Gulf Coast, carrying 700,000 barrels a day of Canadian crude oil; and seems (at least from the animated assertions of Congressional Republicans and the American Petroleum Institute) a perfect solution for the flagging U.S. economy? Answer: TransCanada’s Keystone oil sands pipeline expansion project. Imagine a river of dirty oil running right through the country’s mid-section. Read the entire piece

1988 Switzer Fellow Dr. Mark Schlautman is a professor at Clemson University in the Department of Environmental Engineering and Earth Sciences. A project in which Mark played a key role over a number of years recently made headlines in California. The Brake Pad Partnership, led by San Francisco-based Sustainable Conservation, led the effort to pass legislation reducing the use of copper in brake pads in California.

Switzer Fellow Carol Tucker, who manages the New England Brownfields Program for the US Environmental Protection Agency, explains how brownfields offer major opportunities for community development and revitalization.
