Abstract

In this study, enzymatic treatment was tested to increase the biogas yield of wheat straw (WS) and digested manure fibers (DMF) in the Re-Injection Loop Concept, which combines anaerobic digestion with solid separation to enhance the biogas yield per ton of manure by:1. Digestion of the easily degradable fraction of manure in the biogas process.2. Separation of the residual recalcitrant digested fiber fraction project.3. Ultrasound and/or enzymatic treatment of the digested fiber fraction.4. Recirculation of the treated fiber fraction into the reactor.
