Michelin has announced the construction of an initial industrial demonstration unit for production of the 5-HMF molecule – a bio-sourced and non-toxic molecule which can be used to replace ingredients derived from fossil fuels in a wide variety of industrial fields. The demonstrator will be located in Roussillon, France, and will have an annual production capacity of 3,000 metric tons.
The molecule is already used in Michelin’s ResiCare resins, but this increased capacity will make it viable on an industrial scale, opening up a wide range of potential applications for use. 5-HMF, also known as 5-Hydroxymethylfurfural, is a platform molecule with multiple possible derivatives. It is bio-sourced and non-toxic, so it can be used to replace ingredients sourced from oil or those of concern. The molecule is obtained from fructose that has been transformed using green chemistry processes.
The 5-HMF project, entitled CERISEA, was developed by a partnership framework that brings together multiple industrial, institutional and academic stakeholders. The initial industrial scale unit will safeguard Michelin ResiCare’s supply and make it feasible to lower costs.
“The launch of this initial unit in France, to produce a bio-sourced molecule essential for green chemistry, is a major milestone for taking Resicare’s activities to an industrial scale,” said Maude Portigliatti, director of the Polymer Composite Solutions division at Michelin and a member of the group’s executive committee. “Created at Michelin in 2016, this startup at the cutting edge of innovation will be able to speed up the development of its high-performance and non-toxic resin offers for manufacturers. This new demonstration of the group’s innovative power, the fruit of years of joint research with our partners, also heralds the creation of a new European industry.”
Michelin began to explore alternatives to formaldehyde and resorcinol in the adhesive resins intended for its tires in 2008. In 2013, a technology for tire applications was developed, without using 5-HMF. In 2016, 5-HMF was integrated into the Michelin ResiCare formulae for resins intended for uses other than tires, and initially for plyboard, after identifying a source at a small volume and a high price. After an initial attempt with another partner, Michelin joined forces with the IFPEN in 2021 to develop a more robust production process from fructose, with tests on various scales and engineering studies carried out until the end of 2023.
