San Antonio plans to turn the stench of its residents' waste into sweet green cash and renewable energy. The San Antonio Water System will sell captured methane gas generated from the utility's treatment of 140,000 tons of biosolids, or sewage, from customers each year. The city-owned utility's board of trustees approved a contract Tuesday to provide at least 900,000 cubic feet of natural gas daily for the next 20 years to Ameresco Inc., a Framingham, Mass.-based energy services company. "Treating these biosolids generates an average of 1.5 million cubic feet of gas a day," said Steve Clouse, the water system's chief operating officer. "That's enough gas to fill seven commercial blimps or 1,250 tanker trucks each day." apnews.myway.com Mining mogul Johnson Matthey, Inc. is pleading guilty to allegations that it conspired to cover up illegally high levels of the toxic mineral selenium in the industrial run-off of its silver and gold refining plant in Utah. The plant — operating in Salt Lake City since 1932 — refines precious metals. The wastewater produced during the refinement process requires intensive treatment in order to dispose of accumulated elements, like selenium. Selenium neighbors arsenic on the period table and is toxic when ingested in high concentrations. circleofblue.org Government brokers responsible for collecting billions of dollars in federal oil royalties operated in a "culture of substance abuse and promiscuity" that included having sex with energy company employees, accepting lavish gifts and rigging contracts to favored firms, investigators said Wednesday. apnews.myway.com
