This Alliance project ("R&D of Biomaterials from Agricultural/Forest Residues: from Lab-Scale to Pilot-Scale") aims to realize all-component utilization of agricultural/forest residues. Agricultural residues, such as cornstalk and wheat straw, are very abundant in Canada, particularly in Ontario and Prairie Provinces of Canada. It was estimated that about 18 Mt of oven-dried biomass per year could be available for energy and chemical production from Canadian agricultural residues. On the other hand, the Canadian forestry industry generates hundreds of million tonnes of forestry residues such as forest trimmings (e.g. leaves and branches) and sawmill residues (e.g. wood chips, saw dust and bark). Agricultural/forestry residues are typical lignocellulosic biomass, mainly consisting of three components: cellulose (30-50%), hemicellulose (20-30%) and lignin (20-30%), which are bio-polymers of glucose, xylose and phenyl-propanol. Compared with converting biomass to bio-energy or bio-fuel application, it is more economically promising to convert them to high-value bio-polymeric materials. Our industrial partner - Western Maple Bio Resources Inc. (WMB), committing $681,250 cash and over $250,000 in-kind contributions, is enthusiastic to create a new Alliance partnership with Western University to explore transformative technologies to valorize the crude lignin and crude cellulose derived from agricultural/forest residues for innovative biomaterials: inexpensive and biodegradable lignin-based PF floral foams and cellulose-based bioplastics, and to secure funding to move the above mentioned proprietary technology (lignin-based formaldehyde-free wood adhesives) from lab-scale research to pilot-scale development. The long-term objective of this Partnership is to develop an integrated biorefinery process to realize all-component utilization of agricultural/forest residues for high-value biomaterials. Valorization of agricultural/forestry residues for marketable bioproducts would greatly benefit the agricultural sector in Canada and globally by enhancing its sustainability and creating additional revenue streams and new jobs.

该联盟项目（“农林剩余物生物材料研发：从实验室规模到中试规模”）旨在实现农林剩余物的全成分利用。在加拿大，特别是在加拿大的安大略省和草原省，农业残留物，如玉米秸秆和小麦秸秆非常丰富。据估计，每年约有1 800万吨烘干的生物质可用于加拿大农业残留物的能源和化学品生产。另一方面，加拿大林业产生数亿吨林业残留物，如森林修剪物（如树叶和树枝）和锯木厂残留物（如木屑、锯屑和树皮）。农林废弃物是典型的木质纤维素生物质，主要由纤维素（30-50%）、半纤维素（20-30%）和木质素（20-30%）组成，是葡萄糖、木糖和苯丙醇的生物聚合物。与将生物质转化为生物能源或生物燃料相比，将其转化为高价值的生物聚合物材料更具经济前景。我们的工业合作伙伴- Western Maple Bio Resources Inc. (WMB)承诺提供681，250美元现金和超过250，000美元的实物捐助，热衷于与西方大学建立新的联盟合作伙伴关系，以探索变革性技术，使来自农业/森林残留物的粗木质素和粗纤维素用于创新生物材料：廉价和可生物降解的木质素基PF花卉泡沫和纤维素基生物塑料，并获得资金，将上述专有技术（基于木质素的无甲醛木材粘合剂）从实验室规模的研究转向中试规模的开发。该伙伴关系的长期目标是开发一种综合生物精炼工艺，实现农业/森林残留物的全成分利用，以获得高价值生物材料。将农业/林业残留物用于可销售的生物产品将大大有利于加拿大和全球的农业部门，提高其可持续性，创造额外的收入来源和新的就业机会。
