Clariant to Scale-Up Catalysts for Gevo’s Ethanol-to-Olefins (ETO) Technology

ENGLEWOOD, Colo., May 19, 2016 (GLOBE NEWSWIRE) -- Gevo, Inc. (NASDAQ:GEVO), announced today that it has entered into an agreement with Clariant Corp., one of the world’s leading specialty chemical companies, to develop catalysts to enable Gevo’s ETO technology. As previously disclosed, Gevo’s ETO technology, which uses ethanol as a feedstock, produces tailored mixes of propylene, isobutylene and hydrogen, which are valuable as standalone molecules, or as feedstocks to produce other products such as diesel fuel and commodity plastics, that would be drop-in replacements for their fossil-based equivalents.

Underpinning the ETO technology was Gevo’s invention of proprietary mixed metal oxide catalysts that produce polymer grade propylene or high purity isobutylene, along with hydrogen in high yields in a single processing step from conventional fuel grade specification ethanol. Clariant is committed to the development and scale-up of the catalyst, which is expected to continue the advancement of the ETO technology, while Gevo focuses the majority of its internal resources on the ongoing optimization of its core isobutanol technology. Once the ETO technology has been successfully developed and scaled-up, Clariant will be in a position to produce quantities of the catalyst needed to meet commercial production requirements. As with its isobutanol technology, Gevo anticipates growing its ETO business through licensing.

Gevo has filed a series of patent applications related to this technology. The ETO technology has the potential to provide the estimated 25 billion gallon global ethanol industry a much broader set of end-product market and margin opportunities, beyond the use of ethanol as a gasoline blendstock. It has the potential to address a variety of markets in the chemicals and fuels fields, such as automobile parts, packaging, durable goods made of plastic, renewable diesel fuel and renewable hydrogen for the chemical, energy and fuel cell markets.

"We see the opportunity for Clariant catalysts to convert ethanol, produced from cellulosic or other carbohydrate sources, into more value-added products to create greater growth potential for the ethanol industry," said Stefan Brejc, Head of Specialty Catalysts Business Segment at Clariant.

"We are pleased to be working with Clariant. They have tremendous capability and know-how to scale-up developmental, customized catalysts to enable commercialization of new, large-scale processes. We see the potential with this technology to address several major opportunities cutting across chemicals, plastics, fuels and hydrogen," said Dr. Patrick Gruber, Chief Executive Officer of Gevo.

About Gevo

Gevo is a leading renewable technology, chemical products, and next generation biofuels company. Gevo has developed proprietary technology that uses a combination of synthetic biology, metabolic engineering, chemistry and chemical engineering to focus primarily on the production of isobutanol, as well as related products from renewable feedstocks. Gevo’s strategy is to commercialize biobased alternatives to petroleum-based products to allow for the optimization of fermentation facilities’ assets, with the ultimate goal of maximizing cash flows from the operation of those assets. Gevo produces isobutanol, ethanol and high-value animal feed at its fermentation plant in Luverne, Minn. Gevo has also developed technology to produce hydrocarbon products from renewable alcohols. Gevo currently operates a biorefinery in Silsbee, Texas, in collaboration with South Hampton Resources Inc., to produce renewable jet fuel, octane, and ingredients for plastics like polyester. Gevo has a marquee list of partners including The Coca-Cola Company, Toray Industries Inc. and Total SA, among others. Gevo is committed to a sustainable bio-based economy that meets society’s needs for plentiful food and clean air and water.
