Pyrolysis of tyres. Five facts about rubber processing

Pyrolysis, thermal degradation, is the rubber and used tyres treatment technology based on thermal destruction of raw materials under the high temperatures and lack of oxygen into the products with the smaller molecular mass: liquid pyrolysis oil, carbon black and metal.

The developed technology of rubber disposal is capable to solve the problem of non-polluting waste management. In the natural environment, decomposition of tyre takes an average of 150 years, and is accompanied by a number of leaching of toxic organic compounds into the soil. However, most of the old tyres are stored at landfills, are buried in the ground or burned. All these methods are environmentally unfriendly. No residues, which require disposal is left as a result of the pyrolysis process. Processing products do not contain highly toxic substances; the products of combustion are not released: emissions of harmful substances are below the stated requirements.

The main advantage of the technology is to obtain high quality products. Low-temperature pyrolysis destructs the tires into the components that can be used as intended.

• Pyrolysis oil is the alternative source of energy, which can be used as a boiler fuel or for electric power generation
• Carbon black can be used in mixtures for various purposes: metallurgy, production of paints and building materials, the manufacture of fuel briquettes
• The gas generated during the process can be used for the system operation, as well as to electricity generation
• Metal cord can be used in the metallurgical industry

Pyrolysis is an alternative method of energy recovery that has minimum impact on the environment and is capable to generate both heat and electricity.

Pyrolysis of tyres is the most environmentally friendly and cost-effective treatment technology, which allows processing recyclables, obtaining valuable materials from the waste and generating electricity.
