Tyre pyrolysis plant is an innovative tyre treatment solution. It is designed to recycle waste tyres into valuable products such as carbon black, pyrolysis oil and gas. In recent years, the number of waste tyres has been increasing worldwide. Pyrolysis technology provides an environmentally friendly way to reduce landfill waste while producing usable resources. Tire pyrolysis plant can effectively convert waste tyres into reusable materials, contributing to the sustainable closed loop of tyre recycling.
Tyres are primarily composed of rubber, carbon black, steel, and various chemicals. Tyre pyrolysis plant achieves the chemical recycling. The pyrolysis of tyre occurs under high-temperature, anoxic conditions. When exposed to heat, the rubber components in the waste tyres undergo thermal decomposition, transforming into solid, liquid, and gaseous by-products. The key stages of the pyrolysis process are as follows:
As the core technology, pyrolysis plant not only enables waste recycling but also provide a sustainable solution for resource utilization of tyres .
Tyre pyrolysis oil is primarily composed of hydrocarbon compounds and boasts a high energy density. Its components include aromatic hydrocarbons, aliphatic hydrocarbons, and other olefinic substances.
Carbon black constitutes about 30%-40% of a tyre’s weight. It is a fine black powder with high stability. Due to its non-volatility, carbon black remains as a solid product after pyrolysis.
Inside tire pyrolysis plant, some organic matter decomposes into light gases, mainly including carbon monoxide (CO), carbon dioxide (CO₂), hydrogen (H₂), methane (CH₄), and various light hydrocarbon gases.

2 Types of Oil, 1 Step Collection
In condensation stage, naphtha with a boiling point below 200°C is sent to light oil tank. Non-standard diesel oil with a boiling point above 200°C is sent to heavy oil tank. Fractionation eliminates the need for distillation equipment while obtaining higher quality oil.
50%↑ Processing Capacity
BLJ-20 tyre pyrolysis reactor, with dimensions of ø2800*10000. It offers a 50% increase in processing capacity compared to traditional waste tyre pyrolysis plant. Processing capacity increased from 10-12 tons per batch to 18-20 tons per batch.
No Open Flame, No Oil Gas Leaks
BLJ-20 uses thermal dynamic sealing and flexible high-temperature insulation technology. There are no oil gas leaks or open flames at the operating site. This technology significantly improves operational safety and reduces the risk of thermal hazards.
30 Days Continuous Operation
BLL-30 continuous tyre pyrolysis plant adopts oil-gas spray mixing condensation, the technology quickly lowers temperature and improves condensation efficiency. It prevents olefin compounds from secondary polymerization and clogging the pipes.

Not only fuel oil, tire pyrolysis plant transforms waste tyres into valuable carbon black (rCB). By enhancing the quality of rCB through precise temperature control and advanced processing, the equipment not only support sustainable waste management but also enable significant revenue growth by producing high-value carbon black suitable for various industrial applications.
Precise temperature control is key to ensure high-quality pyrolytic carbon black out put. This technology can optimize the properties of carbon black to meet the following stringent rCB requirements:
The combined grinding and granulation process makes carbon black a high-value product with higher specific surface area and improved particle size distribution. It is reflected in the following two aspects:
The South African customer faces two main challenges: a large amount of non-recyclable plastic and tyre waste, and high fuel costs at the smelting plant. They need an efficient solution to reduce waste and lower energy expenses.
The customer aims to address both waste accumulation and high energy costs by implementing an eco-friendly solution. They identified pyrolysis as the most suitable technology to reduce waste volume, and replace traditional energy sources, thereby lowering operational costs.
Beston Group provides the customer with two BLJ-16 tyre/plastic pyrolysis plants adopts catalytic towers and a BZJ-10 distillation unit. This configuration enables large processing capacity (8-10 tons of plastic and 10-12 tons of tyres per batch), reduces wax oil clogging, and improves fuel quality. The pyrolysis oil serves as a replacement for expensive energy sources at the smelting plant.
BLJ-16 plastic/tyre pyrolysis plant successfully reduced 7,000 tons of plastic and tyre waste annually, converting it into valuable energy resources. Fuel costs at the smelting plant are significantly reduced by using pyrolysis oil for aluminum furnaces and truck fuel. The process also contributes to lower carbon emissions and reduced fossil fuel consumption. Thus, it enhances the customer’s environmental reputation.
Tyre pyrolysis equipment transforms waste tyres into a variety of valuable products. Diversified market demand provides substantial profit sources:
Improper disposal of tire waste can cause serious environmental problems. Tyre pyrolysis plant offers an effective solution that can significantly mitigate these negative impacts:
Tire pyrolysis plant not only effectively solves the problem of waste tire disposal but also plays a crucial role in promoting resource recycling and driving the development of a circular economy:
When the tire pyrolysis machine is started and stopped, the system introduces inert gas (nitrogen) for gas replacement. Through nitrogen replacement, the residual combustible gas and air in the reaction furnace can be effectively removed. Thus, this prevents the flash explosion of the main furnace and ensures the safe operation of the equipment.
Compared with burner heating, the hot air heating system provides more uniform heating and more precise temperature control. Most importantly, the hot air heating system can achieve waste heat recovery, saving 20-30% of energy consumption. Thus, this significantly improves energy efficiency and environmental benefits.
The floating seal technology uses a sealing method that combines carbon fiber and high-temperature soft filler. Compared with traditional graphite filler sealing technology, Beston‘s seal has stronger resistance to high-temperature corrosion and wear. Therefore, it can stably and long-term guarantee the sealing effect of the waste tyre pyrolysis plant.
