Estimation of improved energy balance of anaerobic digestion plant by hyper thermal hydrolysis

Abstract

Anaerobic digestion recovers renewable energy from garbage of municipal solid waste, which is not suitable for incineration because of its high water content However, anaerobic digestion produces digestion residue and high BOD waste water. Adaptation of hyper thermal hydrolysis to dry type anaerobic digester does not require water treatment process, therefore increased the amount of electricity recovery. In this study, we calculated and compared the amount of surplus energy produced by standard methane fermentation and hyper thermal hydrolysis integrated process.
