The specialty chemical maker Evonik Industries will spend what it describes as “a three-digit million-euro sum” to build a rhamnolipids plant at its site in Slovakia.

Rhamnolipids are biodegradable surfactants made via fermentation and feature rhamnose sugar groups with fatty-acid tails. Source: Chemical and Engineering News 19/2/2022
