Increasing the efficiency of organic waste conversion into biogas by mechanical pretreatment in an electromagnetic mill

Year: 2018

Type: conference-paper

Abstract: The article studies the feasibility of using an electromagnetic mill (EM) for mechanical pretreatment of organic waste prior to anaerobic digestion in the laboratory conditions. Pretreatment in an EM led to the significant improvement in the characteristics of subsequent anaerobic digestion of the simulated organic fraction of municipal solid waste. The specific biogas and methane yield increased by 25% and 80%, respectively. The rate of methane production increased by 50%. The degree of volatile solids destruction increased on average by 16%. Economically feasible time to treat the substrate in an EM was shown to be no more than half a minute.
