About

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.  It both saves energy and GHG emissions are 80% lower than those from conventional carbon black production.

Enviro’s recovered Carbon Black (rCB) is now being used in the manufacture of industrial tyres by Hexpol, in Volvo Car components and for pipe seals.  Enviro continues to build interest in rCB with interest now reaching 10s of 1,000s of tonnes per year, including major tyre manufacturers.  In parallel with this Enviro is pursuing several projects in the USA and Europe, incluing the UK.

Over £400 in valuable commodities can be produced from one tonne of used tyres.

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

 ~ 300 kg

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. Leading manufactures are now testing it for use in car tyres.

2G BioPOWER can supply EnviroCB 550 in the UK.

OIL
~ 400 kg

Oil is produced from the synthetic and natural rubbers in the tyre.  The oil comprises ultra light, light and heavy oil.  The ultra light fraction is used in the process. 

Carbon 14 analyses show the oil to be ~ 45% renewable.  2G BioPOWER is therefore exploring opportunities to refine the oil into partially renewable transport fuels.

This objective is in perfect synergy with Formula 1’s aspiration to use 20% biofuel in 2021, especially if F1 uses its own tyres to produce fuel

 


STEEL WIRE

~ 100 kg

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.
