Team uses forest waste to develop cheaper, greener supercapacitors

Read the full story from the University of Illinois.

Researchers report that wood-biochar supercapacitors can produce as much power as today’s activated-carbon supercapacitors at a fraction of the cost – and with environmentally friendly byproducts. The report appears in the journal Electrochimica Acta.

IOM Workshop on Identifying and Reducing Environmental Health Risks of Chemicals in Our Society

On November 7 and 8, the Institute of Medicine (IOM) Roundtable on Environmental Health Sciences, Research, and Medicine will host a workshop on identifying and reducing environmental health risks of chemicals in our society. Industrial chemicals include chemicals used in industrial processes or commercial products, not including those found in food, pesticides, or pharmaceuticals. Through presentations and discussions, the workshop will examine successes and areas for improvement within current regulatory programs for assessing industrial chemical safety, concepts of sustainability and green chemistry that support the design and use of safer alternatives, and innovative efforts to reduce the risk of chemicals in our society. This event will be held in Washington, DC, and is free and open to the public.

A live webcast of the event will also be available for those unable to attend in-person.

 

 
 

Nitrogen Fertilizer Remains in Soils, Leaks Towards Groundwater for Decades

Read the full story from the University of Calgary.

Nitrogen fertilizer applied to crops lingers in the soil and leaks out as nitrate for decades towards groundwater — “much longer than previously thought,” scientists in France and at the University of Calgary say in a new study.

Thirty years after synthetic nitrogen (N) fertilizer had been applied to crops in 1982, about 15 per cent of the fertilizer N still remained in soil organic matter, the scientists found.

After three decades, approximately 10 per cent of the fertilizer N had seeped through the soil towards the groundwater and will continue to leak in low amounts for at least another 50 years.

The study was led by researcher Mathieu Sebilo at the Université Pierre et Marie Currie in Paris, France, and by Bernhard Mayer in the U of C’s Department of Geoscience, and included several research organizations in France.

Their paper, “Long-term fate of nitrate fertilizer in agricultural soils,” was published this week in the Proceedings of the National Academy of Sciences of the United States of America.

South Carolina: National utility leads state in violation of green laws

Read the full story in The State (Columbia, SC).

In the past 20 years, state regulators have slapped Utilities Inc.-owned companies with 55 enforcement orders for water and sewer system violations, according to records kept by the S.C. Department of Health and Environmental Control.

That’s more than any other company or government agency in the state, including the U.S. military, an institution with a legacy of polluting the environment, according to state environmental enforcement records analyzed by The State newspaper. The 55 enforcement cases have resulted in more than $645,000 in fines against Utilities Inc. companies – including Carolina Water Service, one of the Columbia area’s most visible private utilities.

 
 

8 historic buildings that are environmentally friendly

View the slideshow from Mother Nature Network.

When it comes to environmental kudos, ultra-modern buildings usually steal the headlines.

And while the foundations of most historic buildings were laid long before the green construction boom, many of these structures are not the energy-sucking venues that you might expect. In fact, thanks to well-planned renovations, some century-old skyscrapers are among the greenest buildings on the planet.

The following buildings — best known for their historical significance and notable design — have also been recognized for their outstanding environmental friendliness, proving that the green revolution isn’t just for new buildings.

NYC’s big bulb change

Read the full story at Smart Planet.

New York City has 250,000 street light fixtures. And in the next five years, every single one will be replaced with energy-efficient light-emitting diodes.

The LED switch announced this week is part of Mayor Bloomberg’s sustainability program, known as PlaNYC, which aims to reduce greenhouse gas emissions of city government operations 30 percent by 2017.
