In this thesis, a study was undertaken on the premise that the world population living in urban centers is expected to increase from 3.8 billion to 5.2 billion, from 2005 to 2025, representing 54% and 65% of total world population, respectively. The urban population (UP) growth will produce remarkable amounts of urban food waste (UFW) that will add more pressure on already overloaded municipal solid waste (MSW) management systems of cities. This problem is more serious in countries experiencing major economic growth such as China where UP is expected to increase from 44% to 66% of the total co

Abstract:
The management of the organic fraction of municipal solid waste has become a major issue lately in the province of Québec, Canada. Most of it is landfilled today, which increases the burden on landfills and is environmentally unsound. In order to comply with new government guidelines, municipalities have to develop solutions to recover and recycle organic waste. In this context, this study examines two solutions for treating organic waste: home-composting and a separate biodegradable waste collection system combined with large-scale composting. The two scenarios are compared in terms of costs

In a large agricultural operation, such as the one at Cal Poly San Luis Obispo, disposal of deceased animals is an immense issue. The cost of transporting and rendering every dead animal is inhibitory to the general function of the agricultural operations and their thin budget.
