Tabil
Saskatchewan, Canada
Dr. Tabil started at the Department of Agricultural and Bioresource Engineering of the University of Saskatchewan in August 2000. Prior to this position, Dr. Tabil was a Research Engineer with the then Agricultural Value-added Engineering Centre (AVEC) of Alberta Agriculture, Food and Rural Development from October 1997 to July 2000. Prior to joining AVEC, he worked as a Research Associate for over a year at the Department of Agricultural and Bioresource Engineering of the University of Saskatchewan. He worked on an NSERC-funded project on "Alfalfa Cube Quality Characterization". He was also involved in a project evaluating binders in compressed forages. Dr. Tabil's Ph.D. research was on the "Pelleting and Binding Characteristics of Alfalfa". He has expertise in pelleting of feeds and forage and optimizing the process involved in feed and forage processing, physical properties of agricultural materials and postharvest technology of agricultural crops.
Specialties: Bioprocess engineering, value-added engineering and postharvest handling of crops; value-added processing of agricultural products including storage, drying and cooling, and physical properties of agricultural and biological materials.

Experimental trials to make wheat straw pellets with wood residue and binders
Biomass and Bioenergy
Crude glycerol, bentonite, lignosulfonate, and softwood residue (wood residue) were investigated in this study as binders for biomass fuel pellets for thermochemical conversion to enhance pellet quality for transportation and storage. The mass fraction of water of the wheat straw and the wood residue used for pelleting were 0.0676 and 0.0949, respectively. Wheat straw with crude glycerol, bentonite, lignosulfonate, wood residue, and pretreated wood residue with crude glycerol were compressed in a single pelleting unit at a temperature of 95 °C. The specific energy consumption, density, dimensional stability, tensile strength, calorific value, ash content, and chemical composition of the pellets made were determined. Results showed that the specific energy consumption for wheat straw pelletization significantly decreased with the addition of lignosulfonate, bentonite, wood residue, and pretreated wood residue with crude glycerol. With the addition of binders chosen in this study, the tensile strength of wheat straw pellets was improved with values ranging from 1.13 to 1.63 MPa. There was a significant increase in the higher heating value (17.98 MJ kg−1 to 18.77 MJ kg−1) when crude glycerol, wood residue, and pretreated wood residue were used as binders. The addition of both pretreated and non-pretreated wood residue significantly decreased the ash content of wheat straw pellets.
