Industrial hemp has been grown in Canada since its licensing by Health Canada in 1998. Industrial hemp in Canada is used as a commercial source of fibre, oil, and food products. After the seeds are removed, the renewable supply of hemp plants (stalks) are generally left in the field as waste in cases where fibre production facilities are not present. The objective of this study will determine if improvements can be achieved on the absorption capacity of raw and modified forms of hemp by-products for oil, water and oil/water mixtures. Two oil viscosities (light and heavy) will be examined. The research supported by this NSERC Engage Grant will investigate the use of a waste hemp stalks as sorbent materials for use in different industries. The hemp-by product materials investigated will be loose fibers, flour/dust, crumble and pellets. The hemp will be evaluated for its chemical composition such as cellulose, hemicellulose and lignin to determine how the by-products can be modified (chemically and physically) in a cost effective way to increase their absorption capacities. By employing an optimization technique, the best formulation will be identified which will allow recommendations to be made related to their absorption capacity. This research project is expected to deliver a useful product from an otherwise waste material.

自 1998 年获得加拿大卫生部许可以来，加拿大一直在种植工业大麻。加拿大的工业大麻被用作纤维、油和食品的商业来源。在没有纤维生产设施的情况下，除去种子后，大麻植物（茎）的可再生供应通常作为废物留在田间。这项研究的目的将确定是否可以提高大麻副产品的原始形式和改性形式对油、水和油/水混合物的吸收能力。将检查两种油粘度（轻油和重油）。这项 NSERC Engage Grant 支持的研究将调查废弃大麻秆作为吸附剂材料在不同行业的使用。研究的大麻副产品材料将是松散纤维、面粉/灰尘、碎屑和颗粒。将评估大麻的化学成分，如纤维素、半纤维素和木质素，以确定如何以经济有效的方式对副产品进行改性（化学和物理），以提高其吸收能力。通过采用优化技术，将确定最佳配方，从而可以提出与其吸收能力相关的建议。该研究项目预计将从废弃材料中生产出有用的产品。
