Bridgestone Maximising Raw Materials Efficiency
During 2000 and early 2001 the BLIC (Bureau de Liaison des Industries du Caoutchouc), predecessor to the European Tyre and Rubber Manufacturers’ Association, conducted a full Life Cycle Assessment study (LCA) of a representative European 195/65 R15 passenger car tyre, using both carbon black and silica based versions of the H rated summer tyre in the study. Bridgestone, as a member of the Technical Working Group, played an active role in the study.
While, at 84 per cent, the ‘use’ phase of a tyre’s life cycle was identified by the LCA as making the largest contribution to the environmental load of a car tyre, the impact of raw materials, which accounts for 10 per cent, is the second largest factor. Keeping this in mind, Bridgestone Europe comments in its latest Environmental Commitment and Performance report, published November 2008, that the choice of ingredients used is very important, including the promotion of an environmental oriented supply chain.
