Effect of operating parameter on the anaerobic digestion oil palm mesocarp fibre with cattle manure for biogas production

Anaerobic digestion is a complex biological process resulting in the conversion of biodegradable organic matter into biogas and mineralized material. Anaerobic digestion involves the breakdown of biomass by a concerted action of a wide range of microorganisms in the absence of oxygen. The biological...
