Gefn

Gefn is an Icelandic chemical engineering startup focused on producing and commercializing green chemicals for various industries. The company’s innovative technology replaces fossil-based feedstocks by converting low-value by-products, such as glycerol and fatty acids, and climate-neutral CO2 captured through direct air capture (DAC) and biomass fermentation into valuable carbonates and esters. These green chemicals serve as specialty chemicals, solvents, and intermediates in applications ranging from cleaning products and cosmetics to pharmaceuticals and batteries. Gefn’s modular, process-intensification technology allows for flexible, localized production that improves resource efficiency and reduces environmental impact, enabling the chemical industry to shift away from fossil-based hydrocarbons. With a focus on dynamic processes, Gefn optimizes production costs and environmental sustainability, paving the way for a carbon-negative future.
