Solid state anaerobic digestion (AD) technology for the production of biogas is an alternative to popular liquid state systems. The viability of solid state AD with various feedstocks will be evaluated. Two feedstocks were chosen for this study, algae and beef carcass, each mixed with solid beef cattle manure. A bench scale solid state digester unit was used to evaluate the gas production and quality from the feedstock trials. Innoculation strategies were compared in the algae trial with 0%, 10% and 25% inoculum by weight at 40% algae composition and manure making up the remainder. For the beef carcass trial, 25% inoculum was used and carcass content was compared at 5%, 15% and 25% by weight with manure constituting the remainder of the mix. The trials are still underway but will be completed prior to the conference, results and a complete abstract will be submitted at a later date.
