The US Environmental Protection Agency’s AgSTAR program has been critical in developing the biogas industry, many systems of which utilize geomembranes for manure containment and methane harvesting. The 7th National Conference will be held 27-29 March 2012 in Syracuse, New York. The conference provides state-of-the-art information about integrated manure management systems, anaerobic digestion, storage and application techniques, and more.
