Science & Technology

Presidential Green Chemistry Challenge: 2008 Small Business Award

Presidential Green Chemistry Challenge 2008 award winner, SiGNa Chemistry, stabilized highly reactive sodium and lithium by encapsulating them in porous, sand-like powder, maintaining their usefulness in synthetic reactions.

Presidential Green Chemistry Challenge: 2008 Greener Synthetic Pathways Award

Presidential Green Chemistry Challenge 2008 award winner, Battelle, developed a biobased soy toner for laser printers and copiers. The technology saves energy and improves de-inking, allowing more paper fiber to be recycled.

Presidential Green Chemistry Challenge: 2005 Designing Greener Chemicals Award

Presidential Green Chemistry Challenge 2005 award winner, Archer Daniels Midland, developed Archer RC, a nonvolatile, biobased, reactive coalescent that replaces volatile organic coalescents in architectural latex paints.

Presidential Green Chemistry Challenge: 2004 Greener Reaction Conditions Award

Presidential Green Chemistry Challenge 2004 award winner, Buckman Laboratories International, developed Optimyze technology, which uses an esterase enzyme to remove sticky contaminants from paper products prior to recycling.

Presidential Green Chemistry Challenge: 2003 Designing Greener Chemicals Award

Presidential Green Chemistry Challenge 2003 award winner, Shaw Industries, developed EcoWorx carpet tiles with a backing that uses less toxic materials. The carpet tile fiber and backing are readily separated for recycling.

Presidential Green Chemistry Challenge: 2003 Greener Synthetic Pathways Award

Presidential Green Chemistry Challenge 2003 winner, Sud-Chemie, developed a synthesis for solid oxide catalysts used to make hydrogen and clean fuels. The process creates little wastewater, no nitrates, and no or little NOx.

Presidential Green Chemistry Challenge: 2003 Academic Award

Presidential Green Chemistry Challenge 2003 award winner, Professor Richard A. Gross, developed a transesterification to make polyol-containing polyesters using lipase, replacing heavy metal catalysts and hazardous solvents.

Presidential Green Chemistry Challenge: 2001 Designing Greener Chemicals Award

Presidential Green Chemistry Challenge 2001 award winner, PPG Industries, developed cationic electrodeposition coatings with yttrium that resist corrosion in automobiles. Yttrium is a safe replacement for lead in this use.

Presidential Green Chemistry Challenge: 2001 Academic Award

Presidential Green Chemistry Challenge 2001 award winner, Professor Chao-Jun Li, uses metal catalysts in water to carry out chemical reactions that used to need both an oxygen-free atmosphere and hazardous organic solvents.

Presidential Green Chemistry Challenge: 2002 Academic Award

Presidential Green Chemistry Challenge 2002 award winner, Professor Eric J. Beckman, developed fluorine-free detergents that help supercritical carbon dioxide (CO2) dissolve many chemicals, so it can be a solvent for industrial processes.

Presidential Green Chemistry Challenge: 2000 Greener Reaction Conditions Award

Presidential Green Chemistry Challenge 2000 award winners, Bayer and Bayer AG, Covestro, developed high-performance, water-based, two-component polyurethane (PU) coatings that eliminate most or all VOCs and HAPs in other PU coatings.

Presidential Green Chemistry Challenge: 1999 Small Business Award

Presidential Green Chemistry Challenge 1999 award winner, Biofine, developed a process to convert waste cellulose in paper mill sludge, municipal solid waste, etc. into levulinic acid (LA), a building block for other chemicals.
