Integrated Energy-Agro-Waste Systems for Small-Scale Farms

摘要

The feasibility of integrated farming systems for small-scale farms, particularly those smaller than 100 acres, is investigated. Quantitative unit process models are developed for the following agricultural, aquacultural, and waste treatment processes: broiler chickens, layer chickens, beef cattle, dairy cattle, swine, catfish, carp, tilapia, alfalfa, barley, corn, oats, rice, sorghum, wheat, algae, and anaerobic digestion. These models are then combined into an integrated complex and mass balances of the entire complex are performed for each of the complexes considered. The most promising integrated complexes are said to be swine-algae-carp-corn; swine-digester-algae-carp-corn; layer chicken-digester-corn; and layer chicken-algae-tilapia-corn. All of the complexes are said to be technically feasible.
