San Francisco, California – Tire and road wear particles (TRWP) do not pose a threat to human health, according to findings released by the Tire Industry Project (TIP) during its biennial meeting in San Francisco on 17 Nov.
TIP, which is backed by leading tire makers and operates under the umbrella of the World Business Council for Sustainable Development (WBCSD), said extensive ambient air testing had been carried out in major cities of Los Angeles, London, Tokyo and Delhi.
“Results indicate that the presence of TRWP PM2.5 microns in size is very low and below all human health and regulatory thresholds anywhere in the world,” the TIP announced.
The organisation went on to say that additional toxicity testing for one specific targeted chemical in TRWP was conducted to increase its understanding of the life cycle impacts of tires, but did not elaborate further on the results of the test.
The report referred to on-going studies on TRWP in various environments, including air, water, and sediment, stating that “based on a comprehensive risk assessment, the studies demonstrated that TRWP are considered safe for human health and the environment.”
Eleven CEOs of major tire companies met in San Francisco, California as part of the TIP to discuss sustainability within the industry. The leaders, representing approximately 65% of the world’s tire manufacturing capacity, meet every two years to review TIP’s progress.
Additionally, the group discussed sustainable natural rubber and best practices for responsible sourcing of NR.
In alphabetical order, TIP’s member companies are: Bridgestone Corp., Continental AG, Cooper Tire & Rubber Co., Goodyear Tire & Rubber Co, Hankook Tire Co., Ltd., Kumho Tire Co., Compagnie Générale des Établissements Michelin, Pirelli & C. SpA, Sumitomo Rubber Industries, Toyo Tire & Rubber Co., The Yokohama Rubber Co.
Bridgestone, Goodyear and Michelin have served as co-leaders of the group’s work.
