DNP Green Technology and GreenField Ethanol are Partnering to build a Biobased Succinic Acid Deicer Plant Princeton, New Jersey, March 25, 2010, DNP Green Technology and GreenField Ethanol announced a partnership to build a $ 50 million biobased succinic acid refinery that will produce a new generation of environmentally friendly deicing solutions. The succinic acid technology will be licensed from Bioamber. This innovative, biorenewable deicer has a negative carbon footprint and is less corrosive than traditional deicers. Under the terms of the Letter of Intent, DNP Green and GreenField will select a location to build the succinic acid refinery, secure government support and finalize commercial agreements. The partners plan to form a joint venture later this year and negotiate a license from Bioamber. GreenField will build and operate the refinery and DNP Green will hold a significant equity stake. The preferred location is GreenField’s shovelready site in Hensall, Ontario, Canada. The joint venture will produce its next generation deicer from grain derived glucose. This biobased deicer dramatically reduces corrosion to roads, airport runways and aircraft carbon brakes than currently available deicer solutions. This patent protected deicer also meets FAA standards (AMS 1435) and has a negative carbon footprint. The joint venture plans to work with distributors in the various market segments, including Basic Solutions, a provider of innovative runway deicing solutions. “We are pleased to announce our intentions with DNP Green Technology. Adding a biobased deicer refinery to our operations is the start of the realization of the biorefinery potential of GreenField’s extensive grain ethanol operations,” said Bob Gallant President and CEO, of GreenField Ethanol. “Biorefineries will be the 21 st century, futurefriendly equivalent of a traditional oil refinery. Succinic acid deicers and fuel ethanol are just a few of the solutions biorefineries will create to meet some of the greatest challenges our world faces. This new de icer refinery will help decrease greenhouse gas emissions, reduce our fossil fuel dependence and will create economic benefits to the community of Hensall, Ontario, Canada,” added Gallant. GreenField operates four ethanol refineries in Canada. “This is an important milestone in the evolution of biobased chemicals”, said JeanFrancois Huc, President of DNP Green. “We will be North America’s first commercial venture to produce renewable succinic acid. Our initiative illustrates that biobased chemicals are complementary to renewable fuels and a natural evolution for ethanol companies committed to reducing oil
