The high demand for used tires is a direct result of the high profits behind it. After being recycled through thermal cracking, the main products obtained from used tires are three: steel wire, carbon black, and thermal cracking oil and gas.
The steel wire drawn from the tires can be sent to a steel mill for recycling, while the carbon black, after being made into granules by the granulating equipment, can also be used to make permeable plastic running tracks. The oil refining is to use rubber dissolved by high temperature and cooling, plus distillation technology to obtain fuel oil, which can be processed into gasoline later and used as fuel.
According to the information, the proportion of the products obtained from the thermal cracking of waste tires is: oil yield rate of 45%, carbon black extraction rate of 30%, steel wire output rate of 15%, and gas yield rate of 10%. For example, with 10 tons of tires, the profit can be calculated at around 40%.
Secondly, the policy value can also become a driving force for people to recycle tires. In April 2022, the Ministry of Finance and the State Taxation Bureau jointly issued a statement, listing the thermal cracking products of used tires and rubber products as items eligible for tax refund, with the refund rate exceeding 70%.
Many other countries have also established different preferential and subsidy systems to encourage enterprises to handle waste tires in an environmentally friendly way. For example, in Canada and the United States, the policies for handling waste tires in different states are similar, with each state providing a subsidy of $3-5 per tire. In Canada, a subsidy of $60 per ton of waste tires is provided, and the tires used in the project are provided free of charge by the government, so the return on investment is high and has generated good economic benefits while solving the problem of environmental pollution.
