- The BioButterfly project aims to produce bio-based butadiene from ethanol derived from biomass.
- The industrial-scale demonstrator launched in July 2023 with a capacity of 20-30 metric tons per year.
- The project represents a total investment of over €80 million, with €14.7 million supported by ADEME.
- The initiative has created around twenty jobs at Michelin’s site in Bassens.
Project Overview
Michelin, IFPEN, and Axens have inaugurated the first industrial-scale demonstrator plant for producing bio-based butadiene at Michelin’s site in Bassens, France. This initiative is part of the BioButterfly project, which aims to develop and commercialize butadiene from ethanol derived from biomass, replacing petrochemical sources.
Significance of Butadiene
Butadiene is a crucial chemical intermediate used in producing various polymers. Approximately 40% of butadiene is used for elastomers in the tire market, while the remaining 60% is used in varnish, resin, ABS plastic, nylon for automotive applications, textiles, and construction. The shift to bio-based butadiene opens additional market opportunities.
Demonstrator Details
Launched in July 2023, the demonstrator aims to validate each stage of the bio-based butadiene manufacturing process, proving its technological and economic viability. It has a production capacity of 20-30 metric tons per year, facilitating rapid industrial development and global commercialization of the new process.
Investment and Support
The BioButterfly project has received over €80 million in total investment, including €14.7 million from ADEME under the Investments for the Future Program. Additional support has come from the Nouvelle Aquitaine region and the Bordeaux Urban Community. The project has created around twenty jobs at Michelin’s Bassens site.
Future Prospects
The successful demonstration of this technology paves the way for the production of innovative synthetic rubbers without fossil-based resources. The development of a bio-based butadiene sector is expected to lead to the construction of several plants worldwide, meeting the growing demand for sustainable and bio-based finished goods.
