Abstract

The aim of improving knowledge about the stability and reliability of anaerobic digestion of OFMSW, several researchers have studied the effects of operational or environmental variations on the performance of such reactors. In general, anaerobic digestion is affected by changes in external factors and the treatment of anaerobic digestion of OFMSW is, in many aspects of environmental variations mature. Typical topics such as process aspects (performance, two- and single-phase systems), digestion enhancement (pH, moisture, temperature, waste composition, nutrient concentration, particle size, toxicity and inhibition, mixing, granulation and biofilms, loading rates and solid retention time, bioreactor systems for OFMSW pre- and post treatments).
