Clariant, a world leader in specialty chemicals, in cooperation with Werner & Mertz, the producer of Frosch® products, has launched a project which expands the possible applications of bioethanol made from agricultural residues such as straw to detergents, cleansers and cleaning agents. Sunliquid® bioethanol has been used in Frosch® Bio-Spirit Multisurface-Cleaner since the beginning of the year. As part of this, Clariant supplied the cellulosic ethanol, also called bio spirit, at the end of 2015 from its demonstration plant in Straubing, where up to 1 000 tons of cellulosic ethanol are produced annually using the sunliquid® process.

»Bio-based chemicals from local straw, such as cellulosic ethanol, are truly sustainable and advanced active ingredients. The collaboration with Werner & Mertz demonstrates once again that products based on agricultural residues, which are produced without the use of fossil fuels and are not in competition with food supply, are also relevant in the consumer goods sector, « says Professor Andre Koltermann, Head of Group Biotechnology at Clariant.

Werner & Mertz, the family-run company based in Mainz, also welcomes the collaboration. With the “recyclate initiative” for packaging and the Frosch® initiative for “locally-grown active ingredients,” the company has already been engaging in pioneering work in the field of sustainability. Werner and Mertz wishes to further expand this work through the use of another plant-based raw material, the sunliquid® cellulosic alcohol.

Alcohol has been known for its grease and dirt-dissolving properties for decades. Through the use of cellulosic alcohol in Frosch® Bio-Spirit Multisurface-Cleaner, these properties are coupled with sustainable and environmentally friendly manufacturing: due to its virtually carbon-neutral production, cellulosic ethanol saves up to 95 % of CO2 emissions compared to synthetic ethanol from fossil resources. At the same time, it is produced from local residues and does not compete with food production or arable land.
