The goal of this project is to maintain and increase the competitiveness of the Canadian pulp and paper industryby making better use of wood and fibre resources. This will be achieved by applying state-of-the-art technologyand tools to measure wood and fibre quality in the forest, quantify fibre variability, and identify regions withsuperior wood quality in order to extract maximum value from the forest resource. Pulp and paper is the largestmanufacturing industry in Canada and is particularly important to the economy of Atlantic Canada, where theforest industry represents approximately $2.6 billion in real GDP and over 25,000 primary jobs. The proposedresearch, to be conducted in collaboration with partners Paprican and Corner Brook Pulp and Paper, willimprove the cost-competitiveness of the industry by linking incoming fibre quality to process and productperformance, and providing the tools to monitor and control incoming wood quality for improved processstability, reduced operating costs and enhanced product performance.The key objectives of the project are to use state-of-the-art field sensors to measure properties in standing treesor on chip streams feeding Corner Brook Pulp and Paper, establish databases of wood and fibre properties thatcan be incorporated into a digital forest inventory (GIS) framework, and develop models relating key wood andfibre properties to processing parameters and end-product properties. The technical challenges will be to applythe new optical (NIR-based) sensor technologies by developing accurate calibration curves that are specific tothe Corner Brook region of Newfoundland. Although the project is focused on the wood/fibre supply chain ofCorner Brook Pulp and Paper, the industry partner for this project, it will be a demonstration case for theCanadian pulp and paper industry on how to maximize fibre/wood value. An estimated 20 to 30 mills inCanada can potentially benefit from the results of the research.

该项目的目标是通过更好地利用木材和纤维资源，保持和提高加拿大纸浆和造纸业的竞争力。这将通过应用最先进的技术和工具来衡量森林中的木材和纤维质量，量化纤维变异性，并确定木材质量优良的地区，以便从森林资源中获取最大价值。纸浆和造纸业是加拿大最大的制造业，对加拿大大西洋地区的经济尤为重要，林业在该地区的真实的国内生产总值中约占26亿美元，提供了25，000多个主要工作岗位。拟议的研究将与合作伙伴Paprican和角溪纸浆和造纸公司合作进行，通过将进料纤维质量与工艺和产品性能联系起来，并提供监测和控制进料木材质量以提高工艺稳定性的工具，降低运营成本，提高产品性能。该项目的主要目标是使用最先进的利用现场传感器测量为角溪纸浆和纸张提供原料的立木或木片流的特性，建立木材和纤维特性数据库，这些数据库可纳入数字森林清查（GIS）框架，并开发将关键木材和纤维特性与加工参数和最终产品特性联系起来的模型。技术上的挑战将是应用新的光学（近红外）传感器技术，通过开发精确的校准曲线，具体到纽芬兰的角溪地区。虽然该项目的重点是该项目的行业合作伙伴Corner Brook纸浆和造纸公司的木材/纤维供应链，但它将成为加拿大纸浆和造纸行业如何最大限度地提高纤维/木材价值的示范案例。据估计，加拿大有20至30家米尔斯工厂可能从研究结果中受益。
