The global demand for renewable, sustainable, climate-friendly wood pulp materials and products continues to increase. The key to meeting the global fibre demand is through high yield mechanical pulping that produces 50% more fibre than chemical processes. Canada is uniquely positioned with the abundant forests, water and electrical infrastructure required for this energy intensive industry to be successful making it a strategically important, renewable export industry. The single largest threat to this strategic industry is the cost of electrical energy consumed in the process. In BC the mechanical pulping industry consumes nearly 5 TWh/y or 10% of BC Hydro's annual production and represents 1/3 the cost of fibre production. Energy technologies are susceptible to sudden shifts. For example, the move to plug-in hybrid vehicles could quickly and dramatically alter the cost of electrical energy, making current high yield pulp production impractical. The long term survival of this manufacturing sector, which includes newsprint, light-weight coated papers, and market pulp for export into tissue and paperboard, depends on our ability to dramatically decrease the specific energy of these mechanical pulp products. To reduce the energy consumption in mechanical pulping, we have developed a university-industry collaborative research program focused on developing and demonstrating electrical energy reduction technologies, processes and strategies. This program brings together the key stakeholders to form a unique technical team of TMP mills, associated supplier industries, research institutes, universities, utilities and governments agencies. The specific objective of this proposed research program is to develop and demonstrate technologies to produce less mechanical pulp with less than 1000 kWh/t (more than a 50% energy reduction) suitable for a wide range of high quality fibre products, including communication, packaging and tissue products. This proposed program contains three themes aimed at transitioning mills to implement these new technologies and to develop optimization strategies for each sub-process. The 3 themes of the proposal are Process Optimization, Advanced Sensors and Controls, and New Product Development.********

全球对可再生、可持续、气候友好型木浆材料和产品的需求持续增长。满足全球纤维需求的关键是通过高产机械制浆，其纤维产量比化学工艺多 50%。加拿大拥有得天独厚的地理位置，拥有丰富的森林、水利和电力基础设施，这一能源密集型产业的成功使其成为具有重要战略意义的可再生出口产业。这一战略产业面临的最大威胁是该过程中消耗的电能成本。在 BC 省，机械制浆行业每年消耗近 5 TWh，即 BC Hydro 年产量的 10%，占纤维生产成本的 1/3。能源技术很容易受到突然变化的影响。例如，转向插电式混合动力汽车可能会迅速而显着地改变电能成本，使目前的高产纸浆生产变得不切实际。该制造业（包括新闻纸、轻质涂布纸以及出口到薄纸和纸板的商品纸浆）的长期生存取决于我们大幅降低这些机械纸浆产品比能的能力。为了减少机械制浆的能耗，我们制定了一项大学-工业合作研究计划，重点开发和展示电能减少技术、工艺和策略。该计划汇集了主要利益相关者，组成了一支由 TMP 工厂、相关供应商行业、研究机构、大学、公用事业和政府机构组成的独特技术团队。该拟议研究计划的具体目标是开发和示范生产低机械浆的技术，其能耗低于 1000 kWh/t（节能超过 50%），适用于各种高质量纤维产品，包括通信、包装和纸巾产品。该拟议计划包含三个主题，旨在使工厂转型以实施这些新技术并为每个子流程制定优化策略。该提案的 3 个主题是流程优化、先进传感器和控制以及新产品开发。********
