The feasibility of anaerobic digestion of poultry slaughterhouse wastes combined with wastes from a food packing plant was studied using semi-continuously fed, laboratory-scale, continuously-stirred digesters at 35 deg. C and 55 deg. C. Furthermore, factors affecting anaerobic digestion were studied using batch assays with digested material from the digesters. In the mesophilic digester, inoculated with mesophilic digester sewage sludge, and with a loading of up to 4.6 volatile solids (VS) 1~-1 d~-1 (a hydraulic retention time (HRT) of 18 days), the specific methane yield was 330 ml g~-1 VS_added. Nitrogen in the feed was organic nitrogen with a slight amount of ammonium present, while ammonium nitrogen in the digested material accounted for 50 to 70/100 (up to 3.9 g 1~-1) of total nitrogen.
