Jan. 28, 2021--Bridgestone Corporation announced the development of a new technology for improving guayule-derived natural rubber productivity through a joint development project with Kirin Holdings Company, Limited (Kirin Holdings). The project combines the technologies of Kirin Holdings with the guayule cultivation expertise of Bridgestone to deliver large-scale propagation of guayule plants from high-quality seeds. With this innovation, Bridgestone aims to increase the productivity of guayule farms and advance sustainable materials*1 for tires through the diversification of the world’s natural rubber supply.


Bridgestone will field test the new technology on guayule seedlings grown at its 287-acre Agro Operations Research Farm in Eloy, Arizona. The new technology may also be used to support the guayule breeding process to more rapidly increase a desired genotype for testing and production. Through these efforts and others, Bridgestone seeks to develop alterantive and viable sources for tire-grade natural rubber, reducing its long-term environmental impact and simultaneously furthering its business.


Bridgestone is taking steps to decouple economic growth from environmental impacts, as indicated in the United Nations’ Sustainable Development Goals. More than 90 percent of the world’s natural rubber supply is extracted from the Para rubber tree, which primarily grows in Southeast Asia. As part of the company’s Our Way to Serve corporate social responsibility commitment, Bridgestone launched its guayule research and development efforts in 2013 to help diversify the world’s natural rubber supply. Utilizing the Kirin Holdings’ world-class bio technology, we will develop the technology for propagating massive stable quality guayule for practical use. In addition to the Agro Operations Research Farm in Eloy, Bridgestone operates the Biorubber Process Research Center in nearby Mesa, Arizona, where a team processes guayule-derived natural rubber for testing in tire applications.


To achieve the company’s vision, “2050, Bridgestone continues to provide social value and customer value, as a sustainable solutions company,” Bridgestone have set a new environmental mid-term goal, Milestone 2030, to further promote the challenges of "decoupling" the growth of its business from its environmental impact and increased resource consumption. The company provides solutions through innovation to contribute to safer and more secure transportation, as well as it will further reduce its impact on the environment by contributing to CO2 reduction and realizing the circular economy including expanding renewable resources.


Bridgestone will continue to evolve technological innovations by combining our unique rubber knowledge with digital technologies and will co-create value through the work with various partners.
