Narrator: Dr. Richard Engler, US EPA
I'm Dr. Richard Engler of EPA's Office of Pollution Prevention and Toxics. The Dow Chemical Company and BASF were selected as the 2010 winners of EPA's Presidential Green Chemistry Challenge Award in the Greener Synthetic Pathways category. The title of this project is: Innovative, Environmentally Benign Production of Propylene Oxide via Hydrogen Peroxide.
Let me tell you about this award-winning technology. Propylene oxide is one of the biggest volume industrial chemicals in the world. It is a chemical building block for a vast array of products including detergents, polyurethanes, de-icers, food additives, and personal care items and many others. Its manufacture creates byproducts, including a significant amount of waste. Dow and BASF have jointly developed a new route to make propylene oxide via hydrogen peroxide that eliminates most of the waste, and greatly reduces water and energy use.

Narrator: Dr. Richard Engler, US EPA
I'm Dr. Richard Engler of EPA's Office of Pollution Prevention and Toxics. Merck and Codexis were selected together as the 2010 winners of EPA's Presidential Green Chemistry Challenge Award in the Greener Reaction Conditions category. The title of this project is: Greener Manufacturing of Sitagliptin Enabled by an Evolved Transaminase.
Let me tell you about this award-winning technology. Merck and Codexis have developed a second-generation green synthesis of sitagliptin, the active ingredient in JanuviaTM, a treatment for type 2 diabetes. This collaboration has lead to an enzymatic process that reduces waste, improves yield and safety, and eliminates the need for a metal catalyst. Early research suggests that the new biocatalysts will be useful in manufacturing other drugs as well.

Designing Greener Chemicals Award
- Environmentally Friendly Mosquito Larvicide

Narrator: Dr. Richard Engler, US EPA
I'm Dr. Richard Engler of EPA's Office of Pollution Prevention and Toxics. Clarke was selected as the 2010 winner of EPA's Presidential Green Chemistry Challenge Award in the Designing Greener Chemicals category. The title of this project is: NatularTM Larvicide: Adapting Spinosad for Next-Generation Mosquito Control.
Let me tell you about this award-winning technology. Spinosad is an environmentally safe pesticide but is not stable in water and so therefore cannot be used to control mosquito larvae. Clarke has developed a way to encapsulate spinosad in a plaster matrix, allowing it to be released slowly in water and provide effective control of mosquito larvae. This pesticide, NatularTM, replaces organophosphates and other traditional, toxic pesticides and is approved for use in certified organic farming.

Small Business Award
- Engineered Biorefineries
Audio Program (MP3): (284 KB, 57 seconds) Right-click the link to download the MP3 file.
Narrator: Dr. Richard Engler, US EPA
I'm Dr. Richard Engler of EPA's Office of Pollution Prevention and Toxics. LS9, Incorporated was selected as the 2010 winner of EPA's Presidential Green Chemistry Challenge Award in the Small Business category. The title of this project is: Microbial Production of Renewable Petroleum Fuels and Chemicals.
Let me tell you about this award-winning technology. Industrial microbes usually make a single substance, such as triglycerides, much like vegetable oil. That single substance is then purified and converted into other chemicals, such as biodiesel fuel. LS9 has genetically engineered a variety of microorganisms to act like refineries. Each microbe makes a specific, final chemical product. Among these products is UltraCleanTM diesel. This fuel, produced from biomass, eliminates the benzene, sulfur, and heavy metals found in petroleum-based diesel.

Academic Award
- Converting Carbon Dioxide to Fuels
Audio Program (MP3): (320 KB, 1:04 minutes) Right-click the link to download the MP3 file.
Narrator: Dr. Richard Engler, US EPA
I'm Dr. Richard Engler of EPA's Office of Pollution Prevention and Toxics. Dr. James C. Liao of Easel Biotechnologies, LLC and the University of California, Los Angeles was selected as the 2010 winner of EPA's Presidential Green Chemistry Challenge Award in the Academic category. The title of this project is: Recycling Carbon Dioxide to Biosynthesize Higher Alcohols.
Let me tell you about this award-winning technology. Ethanol made by fermentation can be used as a fuel additive, but its use is limited by its low energy content. "Higher" alcohols (those with more than two carbons in the molecule) have higher energy content, but naturally occurring microorganisms do not produce them. Dr. Liao and his colleagues have genetically engineered microorganisms to make higher alcohols from glucose or directly from carbon dioxide. His work makes renewable higher alcohols available for use as chemical building blocks or as fuel.
