NOKIA, Finland—Nokian Tyres P.L.C. has unveiled a sustainable concept tire that is made with 93 percent recycled or renewable materials.
All rubber used in what is dubbed the "Green Step" tire is natural, while renewable oils such as canola oil is used for the processing of the rubber, said Nokian in a Jan. 26 statement.
The tire maker said that the one-year project to design and manufacture the winter tire involved further researching alternatives to natural rubber, including guayule. And almost all plasticizer, resin and processing aids used to produce Green Step were from renewable resources.
The tire maker also employed natural rice husk ash silica as the main filler for the tread and sidewall, and it used renewable cord fiber for the reinforcement of the tire.
