Evaluation of Co-Digestion at a Commercial Dairy Anaerobic Digester

  title={Evaluation of Co-Digestion at a Commercial Dairy Anaerobic Digester},
  author={Craig S Frear and Wei Liao and T. C. Ewing and Shulin Chen},
Co-digestion of dairy manure with off-farmwaste has become a common practice on US farms, however, little data at a commercial-scale is present within the literature. In response, a mesophilic, mixed plug-flow reactor co-digesting 16.36% v/v food processing substrates with dairy manure, was monitored for its performance and substrate effects. Co-digestion, as compared to substrate or manure-only digestion, allowed for more preferred levels of key micronutrients, neutral pH, and additional… CONTINUE READING
