Enviro rCB for Trelleborg

Recovered Carbon Black from Enviro is introduced in a customer-specific rubber compound from Trelleborg Mixing Forsheda

Enviro rCB for Trelleborg Rubber Compounding

Recovered Carbon Black (rCB) from Scandinavian Enviro Systems (Enviro) will be introduced in a customer-specific rubber compound supplied by Trelleborg Mixing Forsheda. The introduction means that Enviro’s rCB takes a step into a new segment and is the result of successful production tests and a long-term collaboration between the parties. Volumes and dates for future deliveries remain to be determined.

Trelleborg Mixing Forsheda manufactures rubber compounds for various companies in the rubber industry and intends to completely replace virgin Carbon Black with rCB from Enviro in one of its customer-specific rubber compounds.

“A transition to rCB gives the rubber mixture the same or better performance than when virgin Carbon Black is used, this is in line with Trelleborg‘s established goals of reducing emissions of CO2 (GWP) from both the company’s processes and products”, says Carl Cumming, material development manager at Trelleborg Mixing Forsheda AB, and continues:

“This is just one of several measures launched within Trelleborg to reduce negative climate impact and be at the forefront of introducing recovered and sustainable raw materials in the rubber industry.”

Recovered Carbon Black has, in light of the increasing topicality of climate and environmental issues, been used in more and more applications in the rubber industry and Enviro‘s rCB has previously been introduced as a replacement for virgin Carbon Black in applications such as seals, gaskets, plugs and solid tyres.

Enviro has also delivered rCB to Trelleborg Lanka for use in the manufacturing of solid tyres. Both Trelleborg Lanka and Trelleborg Mixing Forsheda are part of the industrial group Trelleborg, which is one of the world’s largest producers of industrial rubber. The fact that Trelleborg Mixing Forsheda is introducing rCB in a new application in the rubber industry means that Enviro‘s rCB is now being used in a, for Enviro, completely new market segment.

“Replacing fossil virgin Carbon Black with rCB results in greatly reduced CO2 emissions (GWP), almost 2,000 kilos of CO2 per tonne of rCB, which is an important goal for the rubber industry. We have long worked with Trelleborg Mixing Forsheda to introduce Enviro’s rCB and it is very satisfying that our rCB can now be introduced in additional segments,” says Fredrik Olofsson, Sales manager at Enviro.

Enviro has developed a world-leading technology for recovering end-of-life tyres, which means that strategic and finite resources such as oil, steel and Carbon Black can be recovered. By using rCB instead of virgin Carbon Black in the production of new tyres and rubber components, emissions of climate-affecting carbon dioxide can be greatly reduced, while the recovery of other constituent resources means further reduced environmental impact. According to a life cycle analysis, LCA, conducted by IVL Swedish Environmental Research Institute, the use of rCB can lead to between 79 and 84 per cent lower emissions of the greenhouse gas carbon dioxide compared to production and use of virgin Carbon Black.
