Iowa s biomass stakeholders are collaborating to develop and promote promising biomass resources in the state. The following sections in this Renewable Energy Resource Guide address key developments in Iowa s emerging biomass initiatives particularly those related to renewable transportation fuels, methane recovery, and energy crops. The energy farm uses by-products from each of the farm s activities for other agriculture endeavors. An ethanol plant is the hub of the system, producing ethanol and heat, carbon dioxide, and animal feed. The heat is used in an aquaculture facility for raising commercial fish.
Carbon dioxide is furnished to a greenhouse for commercial produce.
High-protein feed is fed to cattle. In turn, cattle produce manure that can fertilize the corn. Methane captured from the manure is used as a supplemental energy source for ethanol production. In addition, businesses and the public are invited to attend demonstrations, field days and training sessions held periodically at the site. August 31, 1994.
