Anaerobic digestion of fish offal and sawdust

CA-11-03-004

Description

Anaerobic digestion Footnote 1 is an attractive option for manure/waste management because of its potential to digest agricultural and industrial residues, while reducing greenhouse gas (GHG) emissions, mitigating pathogens and odours, and increasing ionized nutrients in the material being digested. This study will test this option by investigating the digestion of fish offal and sawdust using 20-L digesters (microorganisms that break down biodegradable material) under two operational strategies. The digester studies will focus on optimizing biogas/methane production by changing organic loading rates, ratio of fish offal to sawdust, and feeding technique (batch vs. semi-continuous). The biogas/methane yields determined in this study will be used to assess the economic and performance feasibility of a full scale system.
