feasible small-scale anaerobic digestion – case study of eucolino digestion system
DESCRIPTION
Proceedings available at: http://www.extension.org/67722 While large-scale farms have typically been the focus of anaerobic digestion systems in the U.S., an emerging need has been identified to serve smaller farms with between 50 and 500 head of cattle. Implementing such a small, standardized, all-in-one system for these small farm applications has been developed. Small-scale digesters open the playing field for on-farm sustainability and waste management.TRANSCRIPT
