Slovakia: Bioethanol Enviral to Use Clariant's Cellulosic Ethanol Technology

| Editor: Alexander Stark

Enviral has acquired a license to use Clariant's sunliquid technology as part of its goal to realize a full scale commercial cellulosic ethanol plant for the commercial production of cellulosic ethanol from agricultural residues.

Muttenz/Germany — This new plant will be owned and operated by Enviral and is planned to be integrated into the existing facilities at the company's Leopoldov site in Slovakia with an annual production capacity of 50,000 tons. It will use the sunliquid technology as well as starter cultures from its proprietary enzyme and yeast platforms to process feedstock into cellulosic ethanol.

The partners conducted tests of the feedstock with the chosen technology to ensure compatibility. These tests were conducted at Clariant's pre-commercial sunliquid demonstration plant in Straubing (Germany). Next steps are detailed engineering studies before the official ground breaking which is expected at the end of 2017.

As a further step in the commercialization of its cellulosic ethanol technology, the Swiss-based speciality chemicals company decided to set-up a new Business Line Biofuels, as part of the Business Area Catalysis, which is responsible for further developing the biofuels business across the board and report its performance.

Cellulosic ethanol is an advanced and truly sustainable biofuel which is almost carbon neutral. It is produced from agricultural residue such as wheat straw and corn stover that is obtained from farmers. By using agricultural residue, cellulosic ethanol can extend current biofuels production to new feedstocks and improved performance.
