Science & Technology

Presidential Green Chemistry Challenge: 2009 Small Business Award

Presidential Green Chemistry Challenge 2009 award winner, Virent, developed a water-based, catalytic method to make gasoline, diesel, or jet fuel from plant sugar, starch, or cellulose that requires little external energy.

Presidential Green Chemistry Challenge: 2012 Small Business Award

Presidential Green Chemistry Challenge 2012 award winner, Elevance Renewable Sciences, used Nobel-prize-winning metathesis catalysis to produce high-value difunctional chemicals from renewable feedstocks including natural oils.

Presidential Green Chemistry Challenge: 2012 Academic Award (Waymouth and Hedrick)

Presidential Green Chemistry Challenge 2012 award winners, Professor Robert M. Waymouth and Dr. James L. Hedrick, developed a broad class of highly active, environmentally benign, metal-free catalysts for synthesizing plastics.

Presidential Green Chemistry Challenge: 2007 Designing Greener Chemicals Award

Presidential Green Chemistry Challenge 2007 award winner, Cargill, developed biobased polyols for polyurethane applications, including flexible foams. Cargill makes BiOH polyols from vegetable oils, not petroleum products.

Presidential Green Chemistry Challenge: 2006 Designing Greener Chemicals Award

Presidential Green Chemistry Challenge 2006 award winner, S.C. Johnson & Son, developed Greenlist, a rating system for environmental and health effects of ingredients. SC Johnson uses it to reformulate many of its products.

Information and resources on how green infrastructure can help reduce the heat island effect.

Presidential Green Chemistry Challenge: 2003 Greener Reaction Conditions Award

Presidential Green Chemistry Challenge 2003 award winner, DuPont, developed a genetically engineered microorganism jointly with Genencor International to manufacture 1,3-propanediol, a building block for Sorona polyester.

Presidential Green Chemistry Challenge: 1998 Academic Award (Draths and Frost)

Presidential Green Chemistry Challenge 1998 award winners, Dr. Karen M. Draths and Professor John W. Frost, used benign, genetically engineered microbes and sugars (instead of benzene) to synthesize adipic acid and catechol.

Presidential Green Chemistry Challenge: 2000 Greener Synthetic Pathways Award

Presidential Green Chemistry Challenge 2000 award winner, Roche Colorado, developed a greener synthesis for gancyclovir (Cytovene, a potent antiviral drug) that uses a second-generation Guanine Triester (GTE) process.

Presidential Green Chemistry Challenge: 2011 Small Business Award

Presidential Green Chemistry Challenge 2011 award winner, BioAmber, developed an integrated technology to produce large, commercial quantities of succinic acid by bacterial fermentation, replacing petroleum-based feedstocks.
