Muttenz/Switzerland – Clariant and Eta Bio, a company of the Pavlovi family, running a leading business in the agricultural sector in Bulgaria, has announced that a license agreement for the sunliquid cellulosic ethanol technology has been signed.

Eta Bio has been recently established with the purpose to construct, own and operate a full-scale commercial plant for the production of cellulosic ethanol from agricultural residues. For Clariant, the announcement of its fourth license agreement keeps the momentum for its innovative and sustainable sunliquid technology going and represents another significant step towards its commercialisation.

“Our sunliquid technology is trendsetting for the development of sustainable and advanced biofuels. The continued success strongly demonstrates that our technology meets the market needs for sustainable solutions and gives us a competitive edge”, said Hans Bohnen, Clariant’s Chief Operating Officer.

“After signing license agreements with first-generation ethanol producers, as well as mineral oil players, we are excited to also gain a foothold in another important customer segment – the agricultural sector – with our sunliquid technology”, adds Christian Librera, Clariant’s Head of Business Line Biofuels and Derivatives.

Eta Bio will perform the project development and plant operation at a greenfield site in General Toshevo, the Northeastern region of Bulgaria, utilising available land, owned by the Pavlovi family, and existing infrastructure. The annual production capacity is planned to be 50,000 tonnes of cellulosic ethanol, processing around 250,000 tonnes of wheat straw, which is an abundant resource in the region, also known as the granary of Bulgaria.

Specialist Book „Heat Transfer Technique“The comprehensive standard work „Heat Transfer Technique“ offers not only a detailed and well-founded presentation of the basics of heat transfer technique, but also shows the latest state of the art and the latest regulations in the use of organic fluids. Thematically, the book is rounded off with an overview of property data of organic heat transfer fluids as well as many use cases from practical experience.

“The realisation of the first Bulgarian cellulosic ethanol production project will help to solve one of the main challenges agricultural producers face in the region – the removal of the straw from the fields. This project will give us the chance to have an additional revenue stream from agricultural leftovers”, emphasised Kiril Pavlov, Managing Director of Eta Bio.

By using locally sourced feedstock, greenhouse gas savings can be maximised and additional business opportunities along the entire value chain will arise.

“We are excited to enter the renewable energy sector with this project and hence become a pioneer in the advanced biofuels market in Bulgaria. This undertaking will allow us to further diversify our business portfolio, as well as strengthen our position in the agricultural sector”, highlighted Hristo Pavlov, who co-manages the agricultural business of the group.

For Bulgaria, this constitutes an essential investment in green, sustainable technologies. The produced cellulosic ethanol will be used as a gasoline additive to fulfill the country’s blending mandate for advanced biofuels, as laid out in the Renewable Energy Directive (Red) II.

The project is comprised of a license of a sunliquid basic engineering package, the provision of technical services, as well as the supply of starter cultures from Clariant’s proprietary enzyme and yeast platform to process Eta Bio’s feedstock into cellulosic ethanol.
