Conversion of Food Processing Waste to Energy and Fuels
Description: There are about 500 food processing companies in the province of Alberta generating around 0.5 M dry t/yr food waste. At the moment, the food waste is disposed by various disposal approaches among which landfilling is the common practice. Transporting food waste to distant landfills is costly and decomposing the waste in the landfills raises environmental issues. There is a potential to utilize such wastes to produce bio-fuels via a series of conversion technologies. The present study focuses on the assessment of four conversion technologies for food waste processing in Alberta, including anaerobic digestion, composting, saccharification and fermentation, and hydrothermal liquefaction. Comprehensive techno-economic models have been developed to estimate the cost of production of energy and fuels using these technologies. Various cost components including capital cost, operating and maintenance costs, the cost for collecting waste by truck is calculated by estimating transportation distance from waste generation source to conversion facility. GIS-based site selection technique is applied to determine the location for such conversion facility. The total amount of bio-product (methane, ethanol, bio-oil) yield is estimated using standard value production via respective technology. A suitable technology is chosen among the four considering cost and demand for the product. This study would be helpful to policy makers as well as to make informed investment decision for waste management in Alberta.
