Anaerobic digestion of oil-rich solid waste

Võ Hồng Thi

Abstract


Among applications of environmental biotechnology for pollution minimization from organic waste, anaerobic digestion has been supposed to be of advantage because of its cost-effectiveness in initial investment as well as operation. Furthermore, capability of energy recovery from biomass thanks to emitted biogas has been evidenced. Nevertheless, anaerobic digestion of oil-rich solid wastes is not always easy and simple since anaerobes are very sensitive to lipid-rich matters as well as to intermediate compounds of oily wastes degradation process. Therefore, the objective of this paper is to systematically draw a profound understanding of steps, the specific characterstics of each step considering both biochemistry and microbial community during anaerobic digestion resulting in the differences between digestion of oil-rich substrates and other organic wastes. That is also basis on which anaerobic treatment of this type of waste can be successfully carried out.
