US firm turns chicken droppings into energy A US firm has developed a machine that turns chicken droppings into gas and electricity, the company said. “It’s taking a liability and making it into a resource,” said Mike Roberts, senior engineer at the Gas Technology Institute in Des Plaines, Illinois. The goal of the machine is to find an environmentally friendly way of disposing of the billions of pounds of chicken waste produced annually in the United States. Much of that waste is currently used as fertiliser or dumped on fields where phosphates and other pollutants leach into the groundwater. GTI’s solid oxide fuel cell turns chicken droppings and the wood chips they fall onto into a gas that can be used to heat the coops or else be run through a fuel cell to generate electricity. “Generally, this is going to appeal to people in rural areas who have high energy costs” Roberts said. “I don’t see a large power plant using chicken litter.” Roberts said it is too soon to determine how much the machine will cost, but said it is likely the machine would not be used by family farmers. Because one broiler chicken produces just 2.5 pounds of droppings a year, it would be more efficient for farmers to truck the waste to a central facility. The machine could become commercially viable by eliminating dumping fees that farmers face for disposing of the waste and producing revenue from the energy produced, Roberts said. The project was funded by the US Department of Agriculture. The US Department of Energy has also expressed interest in the technology that reduces carbon dioxide emissions and is considered an environmentally benign energy source. A simpler version of the machine that generates gas but not electricity will be ready for commercial use by the end of the year. The complete machine, which will generate gas, electricity and fertilizer, is expected to be available sometime in the next few years, Roberts said. afp dailytimes.com.pk
