At Critical Processes we specializes in clean separation processes to manufacture valuable products from various biomasses. The clean methods use solvents such as water, carbon dioxide and ethanol and therefore do not pollute the environment or leave undesirable solvent residues in the products. These are used in the pharmaceutical, nutraceutical, food-supplement and cosmetic industries.

We also carry out research into clean separation methods for companies developing their own processes. We sometimes build or supervise the construction of equipment for our customers and give them advice and help.

Clean techniques include supercritical fluids (especially carbon dioxide), superheated water (liquid water under pressure above 100°C) and methods using ethanol, ethyl acetate and chromatographic separations.
