Officials from government and industry are also starting to recognize the potential of the Methane Capture Project. The U.S. Department of Agriculture is funding experimental on-farm sites in Mississippi and several other states. Some large poultry processors are launching renewable energy divisions to power their feed mills. And a fuel company is investigating the possibility of pumping chicken-waste methane instead of natural gas through its pipeline, and to use it to power some of the generators along the way.

As a result of some factories using fossil fuels, chemical emissions have already caused serious environmental problems.
