Nokian Tyres introduces its most sustainable tire yet, with its design consisting of 93% of the materials either recycled or renewable.
It moves the company even closer to its goal: by the year 2030, 50% of all raw materials used in Nokian Tyres’ tires will be recycled or renewable.
“Drivers are more and more interested in the sustainability of their tires, and this creates demand for us to create tires for these standards. It also puts pressure on the industry to develop more eco-friendly materials, as well as for tire manufacturing technology to adapt to these materials. With a concept tire like the Green Step, we can push the limits. It’s a win-win for all, but especially for the environment,” says Development Manager Jouko Ilomäki from Nokian Tyres.
All rubber used in the Green Step concept tire is natural, and renewable oils such as canola oil, is used. Almost all plasticizer, resin and processing aids are from renewable resources. In addition, natural rice husk ash silica works as a main filler for the tread and sidewall, and renewable cord fiber is used to make the tire tougher.
“We learned new things with every innovation made for the concept tire. For example, one of the most demanding tasks was to replace the synthetic rubber completely with natural rubber, which we achieved in the end,” Ilomäki says.
The carbon black used in the rubber compounds was derived from end-of-life tires, and the butyl used in the inner surface as well as the steel in the steel belts and bead wires in the structure are mainly recycled.
“We believe that using recycled rubber and especially recycled carbon black will be a future trend in tire manufacturing: by the year 2030, we will have multiple new suppliers and more advanced technology. Also, the demand for raw materials with either recycled or renewed components will increase. We are very happy to be able to corporate so many recycled elements in the Green Step already,” Ilomäki says.
