Linde Gases (Murray Hill, N.J.; www.linde-gases.com) has developed a novel cryogenic technology that promotes uniformity in the formation of ice crystals during freeze-drying (lyophilization) processes for proteins, vaccines and other injectable pharmaceutical products. Lyophilization involves freezing a solution of the product, then reducing the surrounding pressure to allow the water to sublimate...

This month, Borregaard Industries Ltd. (Sarpsborg, Norway; www.borregaard.com) will start up an integrated, pilot-demonstration plant to further develop a new pretreatment process for converting biomass into lignin and fermentable sugars. Located at the company’s R&D Center in Sarpsborg, the pilot plant will convert up to two metric tons (m.t.) of feedstock per day. The fully integrated facility...

A new yeast strain that could one day substitute for petroleum as a source of surfactants for detergents, soaps and cosmetics has been identified by researchers at the U.S. Dept. of Agriculture’s National Center for Agricultural Utilization Research (Peoria, Ill.; ars.usda.gov). The yeast, not yet named, is a member of the Candida genus of yeasts and produces sophorolipids (a sugar-based...

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...

Graphene from dry ice Researchers at Northern Illinois University (NIU; DeKalb, Ill.; www.niu.edu) discovered a new method for producing graphene that involves burning pure magnesium metal in dry ice. The method, which is capable of producing large quantities of graphene in sheets less than ten atoms thick, is simpler than conventional methods for generating graphene, and avoids hazardous chemicals...

A process for making polyols from soybean oil and glycerin has been licensed by its developer, Battelle (Columbus, Ohio; www.battelle.org), to Emery Oleochemicals Americas (Cincinnati, Ohio; www.emeryoleo.com), who intends to produce the renewably sourced polyols at prices similar to those of petroleum-based polyols. As multifunctional alcohols, polyols are widely used in industry, especially for making...

Hiroshi Abe and colleagues at Biochemical Group of Research Institute for Innovation in Sustainable Chemistry, National Institute of Advanced Industrial Science and Technology (Tsukuba, Japan; www.aist.go.jp) have discovered a strain of acetic-acid bacteria (which normally oxidize ethanol into acetic acid) that effectively converts highly concentrated (22%) glycerin into D-glyceric acid. The researchers...
