Green honors

By Gerald Ondrey |

In June, the U.S. Environmental Protection Agency (EPA; Washington, D.C.; www.epa.gov) announced the winners of the 2011 Presidential Green Chemistry Challenge Awards. Winners of the Challenge, which promotes R&D of less hazardous alternatives to existing technologies that reduce or eliminate waste in industrial production, are selected by an independent panel convened by the Americal Chemical Soc. This years honorees include the following (source, EPA): Academic Award. Professor Bruce Lipshutz, University of California, Santa Barbara (www.chem.ucsb.edu), for the design of a safe surfactant, TPGS-750-M, which forms nanomicells (50-100-nm dia.) in water to serve as nanoreactors for organic reactions, such as cross couplings. Reactants and catalysts dissolve in the micells in high concentrations, which leads to increased reaction rates at room temperature. Small Business Award. BioAmber, Inc. (Minneapolis, Minn.; www.bio-amber.com), for the first large-scale production facility for biobased succinic acid (for process details, see CE, April 2007, p. 18). Greener Synthetic Pathways Award. Genomatica (San Diego, Calif.; www.genomatica.com), for developing a microbe that produces 1,4-butanediol by fermenting sugars. Greener Reaction…
