About Molecula
Molecula is an Irish-based renewable chemical technology company focused on optimizing biodiesel production. The company develops specialized chemical solutions designed to overcome fundamental process limitations in the biodiesel industry, specifically addressing the formation of soap during the production process. By applying advanced chemistry, Molecula provides technologies that enable more reliable operations, simplified manufacturing workflows, and the production of high-value renewable chemicals. Their core approach involves process intensification, which eliminates the need for secondary processing steps like water washing, thereby allowing for faster batch turnover and improved economic efficiency for existing biodiesel facilities.
For biodiesel producers, Molecula's systems offer a pathway to improved profitability and operational sustainability without requiring extensive infrastructure changes. By producing high-quality, soap-free glycerol as a byproduct, the company enables facilities to access the broader renewable chemicals market. Their technology, such as the ProCat 50 catalyst system, is engineered to ensure consistent output quality in line with international biodiesel specifications, helping producers maximize their industrial assets and achieve faster capital payback periods.
