ChainCraft develops and exploits proprietary fermentation processes to produce biochemicals from organic residues like food waste, agricultural residues or the organic fraction of municipal solid waste. Its biotechnological process converts different types of organics through its chain elongation technology into medium-chain fatty acids (MCFA), caproic acid or hexanoic acid (C6), butyric acid (C4), valeric acid or pentanoic acid (C5), heptanoic acid (C7) and caprylic acid or octanoic acid (C8).
