replace manure lagoons and spray irrigation systems on swine farms ?
RESPONSE: To-date, NO complete system or suite of technologies has been proven on a commercial farm scale to be both technically feasible and affordable for recommendation on swine farms.

Much has been learned about individual processes for treating manure and other organic materials. Much has been learned about how to improve and make the systems that are currently used work better. For example, some lagoons have been converted to covered digesters where the biogas is collected and used as an energy source reducing the potential for greenhouse gas emissions to the atmosphere.
