DESCRIPTION

http://www.extension.org/67649 Manure from confined animal operations is an environmental liability because of the potential for water and air pollution. The poultry industry in the Chesapeake Bay watershed is under increased regulatory scrutiny due to nitrogen and phosphorous inputs into the Bay. Although poultry litter (PL) is valued as a fertilizer, the cost of shipping the bulky material out of the watershed is prohibitive. One potential solution is to turn the excess litter into energy through pyrolysis. If a market can be developed for poultry litter biochar, more N and P could be removed from the Chesapeake Bay watershed.
