Bridgestone Americas is partnering with LanzaTech to address end-of-life tire waste. The two companies will co-develop the first dedicated end-of-life tire recycling process leveraging LanzaTech’s proprietary CCT (Carbon Capture and Transformation) technology, creating a pathway toward tire material circularity and the decarbonization of new tire production.
According to the Tire Industry Project operating under the umbrella of the World Business Council for Sustainable Development (WBCSD), more than one billion tires globally reach the end of their useful service life each year. Bridgestone and LanzaTech will work to address this issue by converting end-of-life tires into new materials, including exploring processes to create sustainable synthetic rubber that does not rely on petrochemicals.
LanzaTech and Bridgestone are working together to find solutions to some of our world's greatest challenges. We have already proven that we can convert unrecyclable, unsorted municipal solid waste to ethanol and then make products we use in our daily lives. With our partnership with Bridgestone, we are developing a circular pathway to use tires to make tires. This partnership exemplifies what we call a Post Pollution Future.—Dr. Jennifer Holmgren, CEO, LanzaTech
Bridgestone and LanzaTech seek to develop a new business model that will create a post-consumer waste management strategy for end-of-life tires, while also driving increased adoption of sustainably sourced chemicals for commercial applications.
Applying LanzaTech’s carbon capture and gas fermentation process to end-of-life tires yields sustainably produced chemicals such as ethanol that can be converted to materials such as PET for packaging, polyester yarn and surfactants used in consumer home goods like laundry detergent.
In addition, Bridgestone and LanzaTech will jointly explore opportunities to co-develop proprietary microbe technology to produce more efficient pathways to produce butadiene, a key ingredient in new tire production, realizing true circularity for end-of-life tires.
Bridgestone is aiming to achieve carbon neutrality and make tires from 100% renewable materials by 2050. The company is actively researching a range of solutions to support the recycling of materials from end-of-life tires and promote the replacement of non-renewable materials such as oil, silica and virgin carbon black in new tires.
