DOING's waste tyre to oil recycling plant can turn old tyres into pyrolysis oil. The pyrolysis oil can be used as fuel or further refined into diesel fuel.Using the waste tyre to oil recycling plant to turn waste tyres into oil reduces the pressure on landfills and reduces fossil fuel imports. It has good economic and social benefits.
Old tyres(big/small car tyres, truck tires, OTR tyres, motorcycle/bicycle tires) mainly contain hydrocarbons that can be turned into small molecules of oil under the action of pyrolysis at high temperature, so we can use the waste tyre to oil recycling plant to turn old tyres into fuel oil.
How to turn old tyres into fuel oil?
·Turning old tyres into fuel oil: practical tyre recycling solution
The old tyres are piled in the open air for a long time, which not only occupies a large amount of land, but also easily breeds mosquito-borne diseases, seriously aggravates the natural environment, destroys plants and vegetation, and seriously endangers the earth's ecological environment.
Tyres are made of polymer elastomers, which are difficult for microbes to break down. Traditional old tyre disposal way, such as landfill, combustion and other solid waste treatment methods for waste tyres are not applicable and may even exacerbate pollution. Therefore, how to deal with end-of-life old tyres has been recognized as a difficult environmental problem in the world. So, is there a more practical, sustainable and environmentally friendly way to deal with this waste? The answer is yes – pyrolysis, a thermal decomposition process in an oxygen-free environment.

·Turning old tyres into fuel oil step-by-step
Based on the fact that the main components of tyres are hydrocarbons(the building blocks of fossil fuels）, which can be pyrolyzed into small molecules of oil at high temperatures(300–500°C), DOING company developed the waste tyre to oil recycling plant.
The waste tyre to oil recycling plant can safely and environmentally turn the old tyres into fuel oil, non-condensable gases, and solid residues (recovered carbon black and steel).
The main process flow of the waste tyre to oil recycling plant to turn old tyre into fuel oil is as follows:
The main process flow of the waste tyre to oil recycling plant
1.Waste tyres are cut or shredded as needed and loaded into the sealed pyrolysis reactor.
2.Heating waste tyres in the absence of oxygen, waste tyres in high temperature will thermally decompose, but not burn.
2. When the tyre cracks, continue to heat, old tyres will produce oil gas--- pyrolysis vapours (oil gas) and non-condensable gases;
3. The oil gas through professional cooling system（multiple stage shell&tube condensers or water-tank condensers）will be condensed into liquid. Some hydrocarbon shorter length of the steam can not be condensed, will be retained as a gas (similar to propane).
4. Non-condensable gas is collected from the cooling system for purification. It can be routed back to heat the reactor, reducing external fuel needs; surplus can be used or stored as fuel gas.
5. Collect the liquid oil into the oil tank;
6.After the pyrolysis process, the remaining solid materials in tires are primarily carbon black and steel wire. Discharge carbon black and steel wire. These byproducts also have high recycling value: steel wire can be sent to scrap recycling stations, while carbon black can be used in a variety of industrial applications, including rubber products, paints, and inks.
Noted: Proper sealing, temperature control, and a reliable condensation and gas-handling system are essential to minimize emissions and maximize oil yield. DOING modern waste tyre to fuel oil recycling pyrolysis plants include well-sealed pyrolysis reactor, safety valves, professional condensers, and gas recycling systems that improve energy efficiency.
·Pyrolysis Oil: A Versatile Renewable Fuel
Through the thermal pyrolysis process described above, DOING's waste tyre to oil recycling plant can turn old tyres into a valuable renewable fuel—pyrolysis oil, also commonly known as tire oil, tyre drived fuel(TDF), thermal oil, or heavy fuel oil.
Calorific Value: Pyrolysis oil has a high calorific value, typically between 35-42 MJ/kg, comparable to traditional fuels such as diesel and heavy fuel oil, meaning it has excellent combustion properties and energy output.
Tyre pyrolysis oil as heating fuel applications
Applications: Pyrolysis oil is a versatile fuel that can be used directly as fuel in industrial boilers, cement kilns, steel/glass/china making plants, asphalt mixing plants, and other equipment, effectively replacing some fossil fuels, reducing production costs and lowering carbon emissions.
For those seeking higher-value fuel products, the pyrolysis oil derived from our plants is an excellent feedstock for further processing. By utilizing a pyrolysis oil refinery machine, this crude pyrolysis oil can be refined into high-quality diesel fuel, which can be used in boilers and heavy machineries, like trucks, tractors, ships, etc. This advanced refining process opening up even broader market opportunities and maximizing the economic return from waste tires.
