Clariant Certifies Cellulosic Ethanol Plant under European Directives

Clariant confirms its pioneering role in the development of sustainable biofuel from agricultural residues
sunliquid® demonstration plant for the production of cellulosic ethanol receives ISCC certification
Certification expertise creates added value for clients as part of license package

Muttenz, September 3, 2013 - Clariant, a world leader in specialty chemicals, 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).

"The certification of the Straubing plant is a further milestone in the commercialization of the sunliquid® technology," says Hariolf Kottmann, CEO of Clariant. "The biofuel produced in Straubing fulfills and exceeds the sustainability criteria defined in the RED and can be counted toward the climate targets – this is an important prerequisite for establishing the process in the European market."

Alongside REDcert, ISCC is one of two certification procedures for the sustainability of biofuels that are recognized in Germany. ISCC focuses on cutting greenhouse gas emissions, sustainable land use, the protection of natural habitats and social sustainability.

"The ISCC certificate allows us to demonstrate even more clearly to potential partners the efficiency of our technology and the quality of the product from the Straubing plant. Thanks to the 95% reduction in greenhouse gas emissions enabled by the sunliquid® technology, we can offer an almost carbon-neutral process solution," explains Markus Rarbach, Head of the Biofuels & Derivatives project. "The expertise we gained in the certification process is part of the license package we offer our customers. This creates important added value for future plant operators, because only certified biofuels can be counted toward the legally prescribed targets."

The biotechnological sunliquid® process converts agricultural residues such as wheat straw, corn stover and sugarcane bagasse sustainably and efficiently into cellulosic ethanol. Clariant plans to market the sunliquid® process globally, with Europe as one of the core regions.

European laws on biofuels are based mainly on the RED. This directive sets a target for 10% of the energy used in the transport sector to come from renewable sources by the year 2020. Particular importance is attached to advanced biofuels such as cellulosic ethanol, which are not based on foodstuffs and do not cause competition for crop land. These fuels also generate great reductions in greenhouse gas emissions.

sunliquid® is an innovative biotechnological method for manufacturing cellulosic ethanol from agricultural residues such as cereal straw, corn stover or sugarcane bagasse. During the fully integrated process, highly optimized, feedstock specific biocatalysts split cellulose and hemicellulose into fermentable sugars with high yields at stable process conditions. The process-integrated production of biocatalysts offers flexibility and reduces production costs. In the next step, an optimized fermentation organism allows both C5 and C6 sugars to be converted into ethanol, thus increasing the ethanol yield by around 50 percent. An innovative purification process developed by Clariant is instrumental in enabling all the energy required for the process to be derived from the insoluble residue lignin. Since July 2012, Clariant has been operating a demonstration plant in Straubing, which produces up to 1,000 tonnes (330,000 gallons, 1.25 million liters) of cellulosic ethanol from around 4,500 tonnes of raw material every year.
