ChainCraft is a Dutch biotechnology company that develops and commercializes fermentation-based processes to convert organic residual streams into biobased chemicals. Its core technology uses anaerobic fermentation and chain-elongation to produce volatile and medium‑chain fatty acids (e.g., C4–C8) and related derivatives, offering alternatives to fossil- and palm‑based feedstocks.
The company targets applications across animal nutrition, food and feed ingredients, agriculture, personal care, and industrial uses such as lubricants and plastic additives. By upcycling side streams from agriculture and food processing into higher‑value chemical building blocks, ChainCraft contributes to circular production routes and lower‑carbon supply chains within the chemical industry.
