The transport of goods and people is critical for the function of every modern society globally. With the exception of marine and rail transport, every other mode of transport requires vehicles to have tires. Consequently, it is estimated that nearly 5 million tonnes of waste automotive tires are produced in North America and Europe alone. Regrettably, recycling of "off-the-road" (OTR) tires used on vehicles in the mining, forestry and heavy industries until now has not been possible, due to the large size of the tires, as well as their very sophisticated construction. The Rubber Association of Canada (RAC) estimated that there are ~345,000 OTR tires in Canada with no known feasible solution for recycling, while the Canadian Association of Tire Recycling Agencies (CATRA) estimated that ~421,200 tonnes of waste tires were produced in 2019 in Canada alone. The proposed NSERC-Alliance project builds on a very successful 2017 NSERC-CRD project between Kal Tire Mining Tire Group (KT-MTG) and the University of British Columbia (UBC), which focused on the extraction and characterization of recovered Carbon Black (rCB) from OTR tires via pyrolysis. The specific objectives of the Alliance grant are to: 1) Develop and identify processing conditions for upscaling of treatments for the production of rCB originating from OTR tire pyrolysis, 2) Modify and characterize the newly prepared rCB to make it suitable for adaptation in industrial applications (e.g., plastics or pigments), and 3) Prepare rubber compounds (for possible use in tire retread applications) and test their performance in comparison to rubber compounds made with virgin CB. This work has a far reaching implications for the future possibilities of reducing the undesirable environmental impact of waste tires in Canada, reducing CO2 emissions by eliminating dependence on petrochemically-sourced CB, as well as pioneering Canadian technology to recycle OTR tires and repurpose the obtained rCB in the next generation of "green" tires.

商品和人的运输对于全球每个现代社会的功能至关重要。除海洋和铁路运输外，其他每种运输方式都需要车辆有轮胎。因此，据估计，仅在北美和欧洲就生产了将近500万吨废车轮胎。遗憾的是，由于轮胎的尺寸较大，还无法进行采矿，林业和重型产业中使用的“越野”（OTR）轮胎的回收利用。加拿大橡胶协会（RAC）估计，加拿大有〜345,000个OTR轮胎，没有可行的回收解决方案，而加拿大轮胎回收机构协会（CATRA）估计，2019年在2019年生产了约421,200吨废物轮胎仅加拿大。 拟议的NSERC-Alliance项目建立在Kal Tire Mining Tire Group（KT-MTG）与不列颠哥伦比亚大学（UBC）之间非常成功的2017年NSERC-CRD项目基础上，该项目的重点是提取和表征回收的Carbon Black（RCB（RCB） ）来自OTR轮胎通过热解。联盟赠款的具体目标是：1）开发和确定加工条件，以升级由OTR轮胎热解的RCB生产的处理，2）修改和表征新准备的RCB，以使其适合适应工业应用。 （例如，塑料或颜料）和3）准备橡胶化合物（用于轮胎翻新应用）并与用Virgin CB制成的橡胶化合物相比测试其性能。 这项工作对减少加拿大废物轮胎的不良环境影响的未来可能性具有很大的影响，从而通过消除对石油化的CB的依赖来减少CO2排放，并开创了加拿大技术，以回收RCB轮胎和重新释放RCB。在下一代“绿色”轮胎中。
