Avantium again in the Global Cleantech 100

List Recognizes the Top Private Companies in Clean Technology Industry

Avantium, a leading technology company, announced it has been listed for 2nd year in a row in the prestigious Global Cleantech 100, produced by Cleantech Group, a leading research firm focused on global cleantech innovation. The Global Cleantech 100 program is produced in collaboration with the UK's Guardian News and Media.

The Global Cleantech 100 list is unique in the sector because it highlights the promise of private clean technology companies from all around the world, focusing on those companies, which are most likely to make the most significant market impact over the next 5-10 years.

"Being named again in the Global Cleantech 100 list is a fantastic confirmation of our YXY technology. We made enormous progress since the 2010 Global Cleantech 100. We successfully completed a Euro 30 mio financing round. We have signed two new partnerships, with Teijin and Solvay, to develop a broad range of applications. Furthermore we are finalizing a number of exciting joint development agreements with large brand owners for PEF applications, including PEF bottles for water, soft drinks and beer, PEF fibers for apparel and carpets, and engineering plastics for automotive and electronic materials. We are on track with the construction and operation of our YXY pilot plant to prove our process on a larger scale and to do application testing in collaboration with our partners. We are getting closer to create a truly the green economy." said Tom van Aken, CEO Avantium.

The list is derived from Cleantech Group's own data and research combined with the weighted qualitative judgments of hundreds of nominations and the viewpoints of a global panel of 70 cleantech experts. To qualify for the list, companies must be independent, for-profit, cleantech companies that are not listed on any major stock exchange.

"We are proud of how quickly the Global Cleantech 100 list has gained recognition as a leading resource in the cleantech sector," said Sheeraz Haji, Cleantech Group CEO. "Stakeholders including members of the corporate community, investors, and regulators now watch the Global Cleantech 100 list closely to gauge which sectors look most promising and which companies are poised for growth."

4,274 companies were nominated this year from more than 45 countries. These companies were weighted and scored to create a short list of 213 companies presented to the expert panel for final input. The end result was 100 companies from 16 countries.

The 70-strong expert panel is drawn from well-respected organisations in cleantech innovation from around the world, including leading investors in global cleantech and from a wide variety of corporations across many different industries, such as ABB, BASF, BP, Coca-Cola Company, DuPont, GE, General Motors, Procter and Gamble, and Vestas.

"The third Global Cleantech 100 exemplifies the best in cleantech innovation across the world," said Richard Youngman, Managing Director, Europe & Asia, Cleantech Group and the founder of the Global Cleantech 100. "This list is based on the collective wisdom and experience of the world's cleantech leaders and this year it truly reflects not only the most interesting companies, but also the mainstreaming of this dynamic industry."

The complete list of 100 companies is being revealed today at the Global Cleantech 100 Summit & Gala in Washington, D.C. http://events.cleantech.com/global100/. Global Cleantech 100 companies will be featured at this event as well as at the Guardian's Cleantech Summit in London on 22 November 2011 (http://www.guardian.co.uk/cleantech-summit).
