Gills Onions, an onion processor located in Oxnard, California, has a green power system that is expected to produce 35 to 40 percent of the company’s electricity needs. This system will use the waste from the onions they produce to make onion juice which is high in sugars and a favorite of bacteria. The bacteria in turn emit methane gas, which runs the generators. The company also plans to meet their goal of zero-waste by 2011.
