Getting rid of old tyres (轮胎) has long been a problem. Most are thrown into landfills or piled up in storage. Energy recovery is another common method. This involves burning tyres to generate electricity or heat for industries, but that produces planet warming pollution; or we use them to
repair roads, but chemicals from them might pollute the ground.
Some firms, therefore, have begun exploring an alternative. One such firm is Wastefront, which owns a big tyre-recycling plant in north-east England. In a couple of years, it will be able to turn 8 million old tyres into new products, including a black liquid called TDO (轮胎衍生油).
The process works by deconstructing a tyre into steel, rubber, and carbon black. After tearing down the steel, the remaining material is exposed to high temperatures in the absence of air to make the rubber change into a mix of hydrocarbon gases, and then they're removed. What is left behind is pure carbon black. Once the removed gases cool down, a part of them liquefies(液化) into TDO. The remaining gases are to be burned to fuel the process. This creates a closed-cycle system that prevents emissions.
The carbon black can be reused to make new tyres. That is of interest to tyre-makers because it helps efforts to become carbon neutral—achieving a balance between the amounts of carbon dioxide produced and the carbon dioxide removed from the atmosphere. Producing new carbon black requires burning heavy oil or coal, which lets off plenty of greenhouse gases.
The recovered TDO is well-suited for making diesel ( 柴油). While not completely carbon-neutral, it does produce an 80-90% reduction in emissions of carbon dioxide, compared with the conventional fuel. The future market for such cleaner fuels will remain large, even though electric vehicles are on the rise. Fossil-fueled vehicles will exist for decades, particularly the big burners of diesel—trucks, which are harder to electrify. The fuel is also needed by trains and ships. So, anything that helps clean up overall emissions is useful—especially if it also eases a mountainous waste problem.
