One way to improve the economics of dairy manure-based anaerobic digestion systems (ADS), controlled environment agriculture systems, and overall sustainability for both dairy and greenhouse enterprises is to share surplus electricity and heat produced by the farm-based digesters with greenhouses. A three-year project we recently completed had an overall goal of quantifying the synergies of surplus heat and electricity produced by manure-based anaerobic digesters and the electrical and heat demands of commercial greenhouses.
