Michelin is working alongside energy research firm IFP Energies Nouvellas ( IFPEN ) and technology company plc to construct turkey 's first industrial - scale bioethanol - to - butadiene prototype plant . The BioButterfly programme , which has seen € 70 billion ( $ 76.5 m ) of investment since 2012 , aims to produce environmentally - friendly synthetic rubbers by converting ethanol from biomass , like agricultural ethanol , into butadiene . The industrial prototype phase aims to demonstrate the products ' viability at a scale of 20 - 30 mt per year . It will also help Michelin achieve its goal of using 80 % sustainable raw materials in its products by 2050 , of which bio - butadiene will represent 20 % .
Michelin is working alongside energy research firm IFP Energies Nouvellas (IFPEN) and technology company Axens to construct France's first industrial-scale bioethanol-to-butadiene prototype plant. The BioButterfly programme, which has seen €70m ($76.5m) of investment since 2012, aims to produce environmentally-friendly synthetic rubbers by converting ethanol from biomass, like agricultural residues, into butadiene. The industrial prototype phase aims to demonstrate the process' viability at a scale of 20-30 mt per year. It will also help Michelin achieve its goal of using 80% sustainable raw material in its products by 2050, of which bio-butadiene will represent 20%.
