| This project evaluates the performance, environmental impact
and economics of three medium on-farm anaerobic digester systems.
Digester performance will be evaluated as a function of the
size of the system, biogas/energy production, climate and feedstock
utilized (dairy manure blended with high strength organic wastes).
A complete life cycle evaluation assesses nutrient, carbon and
pathogen fate from feedstock to field including: greenhouse
gas emissions (CH4, CO2, N2O), nutrient fate (plant/soil/water/air)
and pathogen attenuation from the digesters, manure storages
and finally land application on three soil types (sandy-loam,
clay and clay-loam soils). |
