Waste biomass animal manures

Biomass. Biomass is simply defined for these purposes as any organic waste material, such as agricultural residues, animal manure, forestry residues, municipal waste, and sewage, which originated from a living organism (70—74). 

The ultimate sources of nitrogen and phosphorus causing cultural eutrophication are industrial N2 fixation, fossil-fuel burning, and the mining of phosphorite. The nitrogen and phosphorus used as fertilizer have three possible 6tes they either enter the food chain, become part of the soil, or are washed off the land by stormwater runoff The nutrients that enter the food chain eventually end up as either animal wastes or dead biomass. Animal wastes include human sewage, livestock manure, and pet feces. Sanitary... 

Another large source of renewable carbon supplies is waste biomass. It consists of a wide range of materials and includes municipal solid wastes (MSW), municipal biosolids (sewage), industrial wastes, animal manures, agricultural crop and forestry residues, landscaping and tree clippings and trash, and dead biomass that results from nature s life cycles. Several of these wastes can cause serious health or environmental problems if they are not disposed of properly. Some wastes such as MSW can be considered to be a source of recyclables... 

A number of different types of domestic biomass resources (also referred to as feedstocks) are used to produce bioenergy. These include biomass processing residues such as paper and pulp, agricultural and forestry wastes, urban landfill waste and gas, animal (including human) sewage and manure waste, and land and aquatic crops. There are basically two...
