Used tyres present both an environmental threat and an opportunity.

2G BioPOWER has an exclusive agreement with Scandinavian Enviro Systems  (Enviro) to bring their market-leading technology to the UK.
Enviro has developed a pyrolysis process that recovers the carbon black and steel in tyres, and converts the rubber to a partially-renewable oil.  This is a major contribution to the Circular Economy.

Enviro's recovered Carbon Black (rCB) is now being used in industrial tyres, Volvo Car components and pipe seals. Enviro is also working with Vanlead, a major car tyre manufacturer, to implement their technology in China, recovering carbon black for reuse in tyre manufacture. This both saves energy and results in 60% lower emissions than those arising from traditional carbon black  production.

Over £300 in valuable commodities can be produced from one tonne of used tyres.


Tyres are shredded and heated without air (pyrolysed) for several hours.  This converts all the rubber to oil and gas whilst leaving steel wire and the original carbon black.

Carbon Black originally used to make the tyres, is recovered along with the other inert fillers. This is milled and beaded for re-use in rubber components. 1kg of virgin Carbon Black is made from ~1.6 litres of fossil fuel. Recycling carbon black (rather than burning tyres) reduces emissions by about 60%.

Enviro’s recovered Carbon Black (rCB) – EnviroCB 550 – is now being used in industrial tyres, Volvo Car components and pipe seals. Vanlead has tested it in car tyre manufacture and is working with Enviro to develop a plant. Other companies are now exploring this option.

2G BioPOWER can supply EnviroCB 550 in the UK.

Oil is produced from the synthetic and natural rubbers in the tyre.  The oil comprises ultra light, light and heavy oil.  The lighter fractions are used in the process; the heavy fraction has has been tested by Wärtsilä and approved for use in their medium speed engines to generate power. Carbon 14 analyses show the oil to be ~ 50% renewable.: the oil could be further processed to produce an ultra-low sulphur partially renewable diesel fuel.

Gas is also co-produced and used in the process leaving partially renewable fuel oil.

Steel Wire is separated from carbon black and briquetted.

This is a high value waste metal and has attracted interest due to the added carbon it carries. It is clear of any rubber and thus causes no issues in furnaces.
