The sunliquid® process developed by Clariant meets all the requirements of a technically and economically efficient, innovative process for converting agricultural residues into climate-friendly biofuel. Using process-integrated enzyme production, optimized enzymes, simultaneous conversion of cellulose and hemicellulose into ethanol and an energy-efficient process design, it has been possible to overcome technological challenges and sufficiently reduce production costs in order to arrive at a commercially viable basis.
Since 2009, Clariant has been successfully operating a first pilot plant at its research facility in Munich. This pilot plant is capable of producing up to two tons of ethanol per year. In July 2012, Germany´s largest plant to date started into operation in Straubing – a demonstration project with an annual capacity of up to 1,000 tons of ethanol.
