Winners of the 2011 Green Chemistry Awards

For the past 16 years the US EPA has been giving out the awards that recognize the most innovative chemical technologies associated with pollution prevention in the US. The 2011 EPA Presidential Green Chemistry awards went to BioAmber, Genomatica, Kraton Performance Polymers and Sherwin Williams as well as Professor Bruce Lipshutz of University of California, Santa Barbara.

Green chemistry is a field of science that is of major importance in efforts to manage climate change. Scientific research and development in this field focuses on less-hazardous alternatives to existing technologies which reduce or eliminate waste particularly hazardous waste, in industrial production.

According to a recent Pike Research Green Chemistry study, the industry is expected to grow from $2.89bn in 2011 to $98.5bn by 2020.

"Green chemistry markets are currently nascent, with many technologies still at laboratory or pilot scale," says Pike Research president Clint Wheelock, "and many production-scale green chemical plants are not expected to be running at capacity for several more years. However, most green chemical companies are targeting large,existing chemical markets, so adoption of these products are limited less by market development issues than by the ability to feed extant markets at required levels of cost and performance."

Pike Research anticipates dramatic growth rates for green chemicals during the coming decade. The global chemical industry is currently valued at $4 trillion. By 2020, the firm expects that the total chemical industry will expand to $5.3 trillion in annual revenues.

BioAmber was given the Small Business Award for its "Integrated Production and Downstream Applications of Biobased Succinic Acid." BioAmber's technology produces succinic acid at a cost 40% below that of petroleum-based succinic acid and can even compete when oil prices are below $40 per barrel. The technology also sequesters carbon dioxide rather than emitting it.

Succinic acid, commonly referred to as amber acid, is a key building block for a wide range of secondary chemicals used in the chemical, pharmaceutical, food and agricultural industries. BioAmber's biosuccinic acid can also substitute for other chemicals like adipic acid in traditional polymers and serve as the starting material for the production of chemicals such as BDO and tetrahydrofuran (THF).

Genomatica, on the other hand, has been recognized for its production of high volume basic chemicals from renewable feedstocks at lower cost under the "Greener Synthetic Pathways Award." BDO, with a 2.8 billion pound, $3 billion worldwide market, is a high-volume chemical building block used to make many common polymers, such as spandex and in automotive plastics.

Genomatica expects its production expenses for bio-BDO should be 15-30% less than petroleum-based BDO and be competitive at oil prices of $45 per barrel or at natural gas prices of $3.50 per million Btu.

Kraton is already well known in the chemical industry and the company received this year's "Greener Reaction Conditions Award." for its NEXAR™ Polymer Membrane Technology. The technology is a family of halogen-free, high-flow, polymer membranes made using up to 50% less hydrocarbon solvent. The NEXAR™ membranes can purify hundreds of times more water than one using traditional membranes. The EPA noted that Kraton's technology also save 70% in membrane costs, and 50% in energy

The NEXAR polymers are reportedly made from block copolymers that provide strength toughness and flexibility, and water or ion transport.

The blog is actually very interested in Sherwin-William's water-based acrylic alkyd technology which was given the "Designing Greener Chemicals Award." Sherwin-Williams is said to have developed its water-based paints (sold under ProClassic Waterbased Acrylic Alkyd,ProMar 200 Waterbased Acrylic Alkyd, and ProIndustrial Waterborne Enamel) made from recycled soda plastic bottle (PET), acrylics and soybean oil.

Sherwin-Williams has used 320,000 pounds of soybean oil, 250,000 pounds of recycled PET, and eliminated 1,000 barrels of oil use as well as over 800,000 pounds of VOCs in 2010.

Professor Lipshutz received the Academic Award. He developed a novel, second-generation designer surfactant called TPGS-750-M made from inexpensive ingredients. The technology is said to offer opportunities for industrial processes to replace large amounts of organic solvents with very small amounts of a benign surfactant nanodispersed in water only. These reactions can even be run in seawater. Sigma-Aldrich is currently offering TPGS-750-M for sale, making it broadly available to research laboratories.

Nice Post...Demand of Chemical Products increasing day by day. It is because of the increasing population. We use chemical products in our daily life in the form of Soap, Polythene etc. Now the chemical companies applies the Principals of Green Chemicals. That is good for the safety of Nature.
