Item 2: Seminar by Louis-Martin Dion:
Biomass Gasification for CO2 Enrichment in Greenhouses

CO2 enrichment in greenhouses has been proven to improve production, whether it occurs from liquid CO2 or the combustion of fossil fuels. The main objective of this research is to demonstrate that such practice could be feasible with the use of a renewable fuel, such as biomass. In the form of wood chips or pellets, biomass has received considerable interest as a sustainable and economically feasible alternative to heat greenhouses. Therefore, using exhaust gases from the combustion process can provide a source of CO2 for a greenhouse and can be an opportunity to reduce CO2 emissions on site. For this research project, wood pellets have been chosen due to their homogeneity, while other sources will be used for comparison (switchgrass, wood chips, municipal solid waste). A gasifier was selected as the main heating and CO2 production unit due to its low particulate emissions. An overview of the project along with early results will be presented.

After starting his degree in mechanical engineering and exploring Italy and Brazil during student exchanges, Louis-Martin completed his undergraduate studies in Bioresource Engineering at 91Ë¿¹ÏÊÓÆµ. He is now pursuing a Master’s degree in Biomass heating and CO2 Enrichment of Greenhouses under the supervision of Dr. Mark Lefsrud.

Item 3: Seminar by Bijaya Adhikari:
Onsite Treatment of Urban Organic Waste

In developed countries such as those of the European Union, stringent legislation for the recycling of urban organic waste (UOW) has forced municipalities to reconsider traditional practices and seek environmental solutions with a minimum economic impact. As an alternative to centralized composting or anaerobic digestion facilities increasing collection and management costs, the onsite-treatment of UOW using home composting methods (HC) can eliminate transportation and labour costs. This study evaluated the performance of four HC as compared to a laboratory reactor. After 22 weeks, the mature compost from all HC exhibited safe product except for that of the rotating metallic drum.

Bijaya Adhikari received his BSc in Agr. Engineering (Hons), MSc in Hydraulic Engineering from IHE, Delft, the Netherlands, and an MSc in Bioresource Engineering from 91Ë¿¹ÏÊÓÆµ, Canada. He has several years work experience in the field of waste and water resources management. He has published many refereed scientific articles in international journals. His areas of research include waste and water resources management. He is a member of Canadian Society of Bioengineering (CSBE), American Society of Agricultural and Biological Engineers (ASABE), Nepalese Society of Agricultural Engineers (NSAE), Nepal Engineers Association (NEA) and Nepal Engineering Council (NEC). Currently, he is doing PhD work under the supervision of Prof. Suzelle Barrington at 91Ë¿¹ÏÊÓÆµ, Canada.

Item 4: Seminar by Mohammed Bakari:
Viability of Biochemical Conversion of Biomass to Bioethanol

Energy security, climate change, and increasing cost of fuel are making bioethanol an attractive alternative or compliment to fossil fuel. The key issue that remains is the viability of the production of bioethanol using   current technologies. In this research, viability analyses based on energy and mass analyses were carried out for the biochemical conversion of the three major groups of biomass to bioethanol.  Rice straw, corn and molasses representing lignocellulose, starchy, and sugar biomass respectively were used for this. The rice straw has the highest efficiency of 31.33 %; corn and molasses have the efficiencies of 28.57% and 28.54% respectively. The mass efficiency of corn was 33.96%, rice straw was 22.96% and molasses was 23.00%.  The results for rice straw are promising, but the process is at experimental stage, while the figures for corn and molasses are based on the operation of existing commercial plants. The analysis indicated that for any of these conversion processes to be viable they will have to be cost competitive with fossil fuel. As well, the byproducts of the bioprocesses must have commercial value.
