Abstract

This research project is focused on examining the feasibility of converting lignocellulosic -based solid waste streams destined for landfill, into a valuable biochar product. Biochar has many applications including a soil amendment to improve soil fertility and in low-cost adsorption applications such as control of odorous sulphur pollutants in air emissions, and as an adsorption surface for toxic metals in industrial waste streams. We have completed an inventory of lignocellulosic -based waste from municipal sources (and expanded our study to include university, demolition and garden wastes). We have produced small amounts of biochar samples and chemically tested their properties for applications stated above. This a long term project, however, through funding from the Harris Centre's Applied Research Fund we have been able to address some of the objectives outlined in the original proposal aimed at diverting a major solid waste stream from landfills to the production of a useful biochar product.
