Metabolix, Inc. (Cambridge, Mass.; www.metabolix.com) has demonstrated, in recently completed greenhouse trials, that switchgrass plants engineered using the firm’s multi-gene expression technology produced significant amounts polyhydroxybutyrate (a polyhydroxyalkanoate; PHA) bioplastics in leaf tissues. The result is said to be the…
BHR Biofuels, a subsidiary of BHR Group (Cranfield, U.K., www.bhrgroup.co.uk), has installed and demonstrated two process-intensified, full-size Biodiesel Reactor Systems at a chemical plant producing biodiesel from waste and virgin oils. The reactor systems are said to consume some 70%…
Rentech, Inc. (Los Angeles, Calif.; www.rentechinc.com) has produced its first run of jet fuel from its Fischer-Tropsch (F-T) product demonstration unit (PDU) in Commerce City, Colo. The plant produces a synthesis gas of hydrogen and carbon monoxide by steam-reforming of…
Conventional cooling systems rely on the properties of gases to cool, but common coolants are either harmful to people or the environment. A different approach is being investigated by researchers at the Dept. of Electrical Engineering, Penn State University (University…
QuantumSphere, Inc. (Santa Ana, Calif.; www.qsinano.com) has commercialized electrodes coated with the firm’s Nano NiFe catalysts for making hydrogen in water electrolyzers. Available in production quantities, the electrodes effectively increase the surface area used in commercial electrolysis by about 1,000…
Time consuming and prone to error, microscopy — the manual counting of yeast cells with a hemocytometer — has long been the primary method for determining the progress of ethanol fermentation. However, a new joint development agreement between Fluid Imaging…
Flowserve Corp. (Dallas, Tex.; www.flowserve.com) has introduced the Valtek Valdisk high-cycle seat, claimed to be a "breakthrough" seat design for Valtek butterfly valves. The new seat design is made of ultra-high molecular weight polyethylene, and offers an ANSI/FCI 7-0-2 class…
Researchers at the University of Surrey (U.K., www.surrey.ac.uk) have discovered a method to make ultra-small, pure crystals of buckminsterfullerene (C60). Lozenge-shaped crystals can be made with widths of 80 nm — much smaller than the 400 nm minimum size predicted…
The global market for carbon-capture technologies was worth $88.7 billion in 2007, and is expected to increase to over $236.3 billion by 2012, according to a report published last month by BCC Research (Wellesley, Mass.; www.bccresearch.com). Postcombustion, the absorption of…
On July 11, the U.S. Environmental Protection Agency (EPA; Washington, D.C.) released an Advanced Notice of Proposed Rulemaking (ANPR) soliciting public input on the effects of climate change and the potential ramifications of the Clean Air Act in relation to…
