Making Rubber From Renewables

Supply constraints and high prices give a bounce to raw materials derived from sugar

The common automobile tire contains rubber that’s extracted from latex-bearing trees and rubber that’s synthesized from petroleum feedstocks. Industrial biotechnology companies such as Genencor, Gevo, Amyris, and Genomatica want to give tire manufacturers a third option: biobased rubber ingredients made from sugar.

Microbial fermentation holds promise for making three renewable rubber intermediates: isoprene, isobutene, and butadiene. Two leading tire makers – Goodyear and Michelin – along with synthetic rubber manufacturer Lanxess have entered into partnerships with industrial biotech firms to advance the commercial production of these rubber intermediates from sugar.
