Butadiene is a key chemical intermediate that is used to produce synthetic rubber, the raw material for a large variety of products of the daily life. About 60% of rubber worldwide production is dedicated for the tire manufacturing industry, which represents a huge potential market.

Moreover, the rubber industry has suffered over the past years from butadiene supply shortages caused by new investments in low-cost gas steam crackers.

Bio-butadiene production with BioButterfly®

BioButterfly® is a technology for producing biobutadiene from bioethanol, designed to offer an alternative solution particularly for the rubber and plastics industries. Thanks to a collaboration between IFPEN, Michelin and Axens, the technological and economic viability of the process was confirmed after 3 years of operation, ensuring its readiness for industrial-scale deployment.

 

Its efficiency relies on proven catalysts and optimized energy integration.
