Sustainable Waste http://wunc.org en Chemicals In Human Waste Can Harm Crop Land http://wunc.org/post/chemicals-human-waste-can-harm-crop-land <p></p><p>Many farms spread human waste on cropland to fertilize it. In this case, the waste is called "biosolids". It can carry household chemicals that affect important bacteria, and that can hurt soil health.</p><p></p><p>The government has had a hard time regulating chemicals in biosolids, because the equipment that measured bacterial gases was very expensive.</p><p></p><p>But a new report from Duke University's school of engineering shows that bacterial reactions to chemicals can be assessed by changes in color. That's a cheaper test to administer.</p><p></p> Mon, 24 Feb 2014 12:50:56 +0000 Rebecca Martinez 31055 at http://wunc.org Chemicals In Human Waste Can Harm Crop Land Wake County Landfill Buys 10 More Years http://wunc.org/post/wake-county-landfill-buys-10-more-years <p></p><p>The amount of garbage headed to the Wake County has dropped significantly in the past few years.</p><p></p><p>In 2009, the county buried 460,000 tons of garbage.

The new operations center was built to LEED platinum standards - the highest level of sustainability certification. City manager Russell Allen says the building was constructed with re-used and recycled materials where possible. It includes solar panels and geothermal systems; and will have plug-in electric vehicles.<br> Thu, 26 Jan 2012 07:30:00 +0000 Isaac-Davy Aronson 3376 at http://wunc.org UNC Recycles Methane from Landfill http://wunc.org/post/unc-recycles-methane-landfill <p>Orange County and UNC Chapel Hill are working together to make productive use of a landfill gas. Methane originates from the decomposition of organic materials such as food. The collaboration will collect methane from the county's landfill and use it to produce electricity using a generator at UNC. Ray DuBose is the director of UNC Energy Services. He says projects like these are not without precedent.<br> Mon, 26 Dec 2011 09:50:00 +0000 WUNC News 7059 at http://wunc.org
