ZeaChem Executes Joint Development Agreement with Procter & Gamble

ZeaChem Inc., a developer of biorefineries for the conversion of renewable feedstocks into sustainable fuels and chemicals, today announced a binding multi-year joint development agreement with Procter & Gamble (NYSE: PG). The agreement will accelerate development of ZeaChem's product platform beyond C2 through the commercialization of “drop-in” bio-based chemicals and other products.

“As part of its long-term environmental sustainability vision, P&G is committed to using 100% sustainably sourced renewable or recycled materials for all products and packaging,” said Len Sauers, P&G's vice president for global sustainability. “Novel innovations from our suppliers, such as ZeaChem's unique process to create bio-based chemicals, are critical to us achieving this vision.”

“We're very pleased to partner with Procter & Gamble, a global leader in consumer products and sustainable operations,” said Jim Imbler, president and CEO of ZeaChem. “This definitive agreement will accelerate the time to market for our new product platform and the commercial production of economical and sustainable biofuels and bio-based chemicals using ZeaChem's highly efficient technology.”

ZeaChem's process uses renewable feedstocks such as poplar trees and agricultural residues to produce the highest yield and lowest carbon emissions of any known biorefining technology. The company has begun fermentation work on this new product platform using the same processes and equipment that the company used to prove and scale up its C2 product platform. The new platform also enables ZeaChem to ultimately deploy its technology for the production of other bio-based chemicals as well as drop-in fuels. The two companies will utilize ZeaChem's existing infrastructure at its lab in Menlo Park, Calif., pilot facility at Hazen Research in Golden, Colo., and demonstration-scale biorefinery in Boardman, Ore. Together, P&G and ZeaChem will research, develop and demonstrate, scale-up, and commercialize this new product platform.

About ZeaChem Inc.

ZeaChem Inc. has developed a cellulose-based biorefinery platform capable of producing advanced fuels and intermediate chemicals. ZeaChem's indirect approach leapfrogs the yield and carbon dioxide (CO₂) problems associated with traditional and cellulosic based biorefinery processes. In addition, ZeaChem has a significant capital cost advantage compared to other cellulosic technologies. By efficiently extracting the most energy possible from biomass feedstocks, ZeaChem significantly increases output while reducing both production costs and environmental impacts. Incorporated in 2002, ZeaChem is headquartered in Lakewood, Colo. and operates a research and development laboratory facility in Menlo Park, Calif.
