Impact of substrate heterogeneity on anaerobic co-digestion process: a review

Abstract

Anaerobic co-digestion is one potential strategy for maximizing the infrastructure's capacity for treatment while improving biogas output. It involves the addition of two or more substrates being digested simultaneously in the process. Anaerobic co-digestion's primary goal is to increase biogas, mostly bio-methane for domestic heating activities and electricity. By increasing bio-methane yields, anaerobic co-digestion becomes an effective and proficient method for reducing the limitations of mono-digestion and enhancing the commercial efficiency of existing anaerobic co-digestion amenities. By co-treating two or more waste streams, improved biogas generation can be accomplished through anaerobic co-digestion.
