About Re:Chemistry by GFBio

Re:Chemistry, a division of GFBio, was established in 2013 and headquartered in France, to transform bio-residues into high-value chemicals and raw materials. Through its circular-economy approach, Re:Chemistry drives innovation in sustainable ingredient sourcing. In adhesives, it supplies bio-based solvents like ethyl levulinate (SOLV100) and butyl levulinate (MOVE200) as low-toxicity alternatives. These offer excellent solvency and compatibility in coatings-integrated adhesives and sealants for sustainable formulations.

Levulinic ketals

Produced using Segetis' Javelin™ technology, Levulinic ketals is a broad family of bio-based compositions with performance advantages in many applications. The chemical structure of Levulinic Ketals gives them valuable inherent traits like thermal stability, low toxicity, broad compatibility due to high oxygen content, and high boiling point. Enabled by the development of selective ketalization of levulinic acid esters, these compounds have broad solubility enabling their use as cleaning solvents or coupling agents in liquid formulations. When extended by trans-esterification, levulinic ketals can make effective plasticizers for a range of plastic compounds including PVC, can make polyols for polyurethane materials and can be extended for use in polyester thermosets or thermoplastics.

Levulinic Acid

Levulinic acid. It is a carbon-based compound (C5H8O3) derived directly from biomass. Its high conversion yields improve efficiency, while reducing waste and cost. Synthetic versatility allows for various downstream transformations and production of valuable derivatives. It is an excellent non-toxic antimicrobial that extends product shelf life. Levulinic acid has been recognized by the US Department of Energy as a potential biobased building block.
