Description: Microwave pyrolysis is an emerging technique to produce biochar from biomass materials. Different biomass materials such as maple (hardwood), spruce (softwood) and switchgrass (energy grass) are widely available in New Brunswick (NB), Canada. The government of NB is promoting innovative techniques to convert biomass waste to value added products. This study, thus, aims to produce biochar from locally available biomass waste materials and then to determine the characteristics of the biochar. Microwave pyrolyzer developed in the Bioenergy and Bioproducts Research Lab at University of New Brunswick was deployed to produce biochar. Experiments were conducted under a set of power levels: 400, 500, and 600 Watts, keeping residence for an hour. Preliminary results showed that biochar product yields varied from approximately 20-25%, with higher yields being obtained at lower power levels. The highest surface area of 205 m^2/g at 500 W and porosity of 0.1 cc/g at 400 W were observed in spruce biochar. Further, biochars will be characterized in terms of elemental and proximate analysis to better understand biochar compositions and quality.
