What is Pyrolysis Oil
Pyrolysis Oil from Waste Tires is one of the renewable resources obtained by decomposing used tires at high temperatures. Tires are typically made up of multiple materials such as rubber, fibers, and steel. Pyrolysis oil is derived by thermally breaking down the rubber component into liquid oil.
This process is conducted in an oxygen-free environment and has gained attention as an alternative energy source to fossil fuels. Pyrolysis oil from waste tires is primarily used as fuel, finding applications in industries such as automotive manufacturing and power plants. Additionally, further refinement allows it to be utilized as chemical feedstocks or industrial-grade oils.
This technology addresses the environmental issues associated with the massive disposal of waste tires while promoting resource recycling, contributing to the development of a circular economy. It is not only of interest in environmentally conscious countries in Europe and North America but also in nations like India and Malaysia, where high taxation on petroleum fuels drives demand for cost-effective alternative fuels.
To simplify for those who is unfamiliar with the concept, pyrolysis oil from waste tires is a method of transforming waste tires into a “new and valuable resource.” This action does not only support environmental conservation but also plays a crucial role in moving forward to a more sustainable future for all.
Waste Tires Problem in Southeast Asia
Southeast Asia has recently garnered attention as a region where waste tires are increasingly accumulated. The primary reasons for this are the development of the recycling industry and the low processing costs in the region. Waste tires are often exported from developed countries due to high disposal costs, and in Southeast Asia, they are used as raw materials for producing tire-derived fuel (TDF) and reclaimed rubber. Notably, Thailand, Malaysia, and Indonesia have numerous recycling facilities currently in operation.
However, there are challenges. Inappropriate disposal methods have led to issues such as air pollution, and abandoned waste tires serve as breeding grounds for mosquitoes that transmit dengue fever, raising concerns about environmental and public health impacts. In response to these issues, there has been a growing movement in recent years to strengthen import regulations on waste tires.
How Much Oil Can Be Extracted from Waste Tires?
For example, from 100 tons of waste tires, approximately 20 tons of steel wire, 45 tons of pyrolysis oil, and 35 tons of carbon black can be obtained. (To be precise, byproducts such as pyrolysis gas are also generated, but this page focuses on approximate figures.)
Moreover, through distillation, 45 tons of pyrolysis oil can be refined into approximately 25 tons of heavy oil-grade pyrolysis oil and 15 tons of diesel-grade pyrolysis oil.
Carbon black: By products from waste tires
35% of the total weight of waste tires can be extracted as carbon black. This carbon black is utilized in applications such as paint production or as a material for new tires. However, the carbon black obtained directly from waste tires contains many impurities and is not of high quality. Through subsequent processes involving proper filtering and grinding, the quality can be improved.
In a nutshell
Pyrolysis oil from waste tires is an innovative and eco-friendly solution for managing tire waste while producing valuable fuel. It reduces landfill accumulation, minimizes pollution, and provides an alternative to conventional fossil fuels. Additionally, the process supports a circular economy by repurposing byproducts like carbon black and steel. By converting waste into energy, pyrolysis contributes to a more sustainable and cleaner environment.
