Formatted Abstract/Summary
Hemp hurd, also commonly referred to as hemp shives, is a low cost byproduct from the decortication process of hemp, retailing for less than 0.2 $/kg. In the context of establishing a hemp agri-fibre operation, value adding to this underutilized waste stream is crucial to improve the overall economics of the operation. In this research the use of hemp hurd as an alternative to wood flour for the production of wood plastic composites is investigated. Hemp hurd filled Polypropylene composites were produced via compounding in a co-rotating twin screw extruder. Taguchi design of experiment methodology in combination with Analysis of Means (ANOM) was used to gain an understanding of the influence of the different processing parameters. Parameters investigated were screw configuration, temperature profile and fibre loading. Best results were obtained with a relatively gentle mixing zone at a temperature of 200 ⁰C and 40%wt. and 20%wt. of fibre loading for highest stiffness and highest strength respectively.
