Specialty chemical firm Clariant has received the International Sustainability & Carbon Certification (ISCC) for its sunliquid® demonstration plant in Straubing (Germany), which was opened in July 2012. The certificate confirms that the cellulosic ethanol from agricultural residues produced with the sunliquid® technology is compliant with the sustainability criteria set out in the European Renewable Energy Directive (RED). Clariant plans to market the sunliquid® process globally, with Europe as one of the core regions.
