Carbon black from used tires**

点击翻译按钮获取中文摘要

Used tires occupy considerable space in landfills, especially tires from mining trucks, which are greater than 2 m in diameter. Titan Tire Reclamation Corporation (TTRC) has developed a unique environmental solution to process giant scrap mining tires that have been accumulating in Alberta's Oil Sands. When tires can no longer be repaired, they are fed to a Thermal Vacuum Recovery unit in which they are subject to a proprietary process that breaks the tires down into their key components. The products from this process include carbon black, low carbon fuel oil, and steel. The first product can be recycled for tire production provided that the recovered carbon black has the same properties as virgin carbon black material. In this project, Professor Josephine Hill will work with TTRC to assess the properties of the recovered carbon black produced in their vacuum recovery process. ****Professor Hill's group has extensive experience with carbon-based materials. They will evaluate the properties of the virgin and recovered carbon black materials. Based on the characterization results and small scale tests, they will make recommendations for adjustments to the recovery process in order to meet the required specifications for the carbon black. In this way, TTRC will be able to realize a circular economy with its tires, resulting in lower amounts of waste, greenhouse gas reductions, a sustainable solution for spent scrap mining tires, and economic development.****
