As the world’s population grows past the 7 billion mark and more people move to urban areas, the amount of waste generated will grow accordingly. The most promising solutions to this problem are waste to energy technologies in the form of biological treatment of organics through anaerobic digestion and thermal decomposition via plasma arc gasification. These two technologies can be used in the urban environment separately or complimentarily to reduce the volume of the waste being processed while also generating heat and power (CHP) and reducing transportation costs and greenhouse gas emissions. In this research, the feasibility of heating a small-scale anaerobic digester using an air source heat pump and solar heat gains from a greenhouse located on the roof of an urban building in Montreal, Canada, is investigated during the coldest month of the year. Small-scale implementation of anaerobic digestion systems for back...

As landfills across Canada and the rest of the world are filled to their limits, a carbonneutral process which can locally generate electricity and heat while providing up to 50% volatile solid reduction is something to be seriously considered. This paper investigates the feasibility of urban anaerobic digestion, presents four techniques for biogas estimation e ultimate analysis, yield from molecular formula analysis, a novel computer simulation technique using Anaerobic Digestion Model #1 (ADM1), and a literature review of experimentally determined biogas yields. In addition, a case study for small-scale anaerobic digestion system design is presented for an urban building.
