Bridgestone Corp. And Ajinomoto Co., Inc. Jointly Developing Synthetic Rubber from Biomass
11 Jun 2012
The Goal is to Develop Tyres with 100% Sustainable Materials
Bridgestone Corporation today announced that it has successfully polymerized (* 1) high-cis polyisoprene (IR * 2) synthetic rubber from isoprene (* 3)
provided by Ajinomoto Co, Inc., a partner in synthetic rubber development for tyres. Isoprene is produced with biomass.
Demand for tyres is expected to increase in tandem with rising car ownership worldwide, and the Bridgestone Group is committed to promoting the development
of technologies and business models that contribute to greater use of recyclable and renewable resources in order to build a sustainable society.
The Bridgestone Groups is promoting a variety of initiatives for creating “100% sustainable materials” (*4) by 2050, but IR extracted from crude oil
feedstock is a market with limited potential for supply.
The Group has been searching for ways to procure raw materials from renewable sources to ensure the supply of sustainable resources. Polymerized IR has
been successfully polymerized at this time using isoprene produced with biomass by Ajinomoto, which has the world’s most advanced fermentation
This development could be a major catalyst for achieving the Group’s goal of a sustainable society. In addition, IR bonded with isoprene from biomass
feedback using the Group’s proprietary polymerization catalyst (*5) technologies can verify the practical feasibility of IR.
Since IR can replace natural rubber in some cases, the Group expects it to be one of the means of diversifying raw material sources for tyres. Looking
ahead, the Bridgestone Group aims to promote IR bioengineering technologies while confirming its rubber properties and further enhancing polymerization
catalyst technologies for developing IR with more advanced performance features.
Through efforts such as the research into biomaterials, for both natural and synthetic rubber, the Bridgestone Group is looking to develop tyres “100%
sustainable materials” (renewable and recyclable resources). The Group is involved in other efforts to develop concept tyres made from “100% sustainable
