Description: The goal of this study was to determine the ability of microwave-chemical pretreatment to enhance compression characteristics and densification process of canola straw grind. In this study, ground canola straw samples were immersed in alkaline (sodium hydroxide and calcium hydroxide) solutions and then exposed to microwave radiation. Chemical composition, bulk, and particle densities of samples were determined before and after pretreatment. Untreated and microwave pretreated samples with 12% (w.b.) moisture content were compressed at four levels of compressive forces (1000, 2000, 3000 and 4000 N) in a plunger die assembly and the compression and relaxation test data were recorded. The specific energy required for compression and extrusion of pellets produced from untreated and pretreated canola straw grinds was calculated. The fracture load and tensile strength of the pellets were also evaluated to investigate the hardness of the pellets. Chemical composition analysis showed that microwave pretreatment was significantly able to disintegrate the lignocellulosic structure of canola straw grinds. Data analysis also revealed that the pellets made from microwave pretreated biomass grinds had a significantly higher density and tensile strength than untreated samples.
