Abstract

Biogas production through anaerobic digestions of organic wastes using microbes is a potential alternative to maintain the long term sustainability of the environment and also to full-fill the energy demands and waste management issues. In this context, pressmud can be a vital substrate which is generated from sugarcane industries and found to be broadly available. In this work, biogas improvement has been investigated in presence of CuO/Cu₂O based nanocatalyst wherein pressmud is employed as a substrate in anaerobic digestion. Herein, CuO/Cu₂O based nanocatalyst has been prepared using the aqueous extract prepared from the combination of PM and SCB which is employed as a reducing agent. The physicochemical properties of CuO/Cu₂O nanocatalyst have been probed through different techniques and it is noticed that using 1.0 % CuO/Cu₂O based nanocatalyst employed in AD process, cumulative biogas 224.7 mL CH₄ /g VS could be recorded after 42 days.
