An inventory within a 40km radius of Olds revealed that almost 600,000 tonnes of waste are generated annually (98.4% manure) with an electrical potential of 83 GWh. Analysis of beef, hog, dairy and poultry manure, offal, food, grass and biosolids identified the potential for waste blending to optimize solids content and nutrient balance. In laborat01y tests, biogas yield increased from 0.382 m3/kg volatile solid (VS) with beef manure to 0.513 m3/kg VS with co-digestion of 30% hog manure, and 0.500 m3/kg VS with 30% offal. In pilot tests, methane content was increased from 58% to 63% through co-digestion of beef manure with beef manure. The increased yield observed in the laboratory tests was not confirmed due to process inhibition and the limited capability for process control in the pilot digesters.xv, 248 leaves : ill. ; 30 cm.engUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
