Resumé

The re-injection loop concept proposes the recirculation of lignocellulosic organic matter after a first cycle of anaerobic digestion in order to increase the conversion into biogas. This re-circulation can potentially increase the methane yield up to 20%. In this study thermal and enzymatic treatment of the digested manure fibers (DMF) in combination with the re-injection loop concept were tested. Thermal treatment of DMF at 105oC showed an increase of the specific methane yield of DMF by 65% while no siginificant effect was observed for enzymatic treatment of DMF for 1 h prior to recirculation into the digester.
