Chementator: Taking Advantage of Landfill Gas
Dow Chemical (Midland, Mich; www.dow.com) has started using a renewable energy source — methane from landfill gas — at its Dalton, Ga., plant where carpet latex is manufactured. As a result, carpet-backing products manufactured with the so-called Dow Lomax technology,…
Chementator: A New Process for Making Solar-Cell-Grade Silicon Slated for Commercialization
Chisso Corp. (Tokyo, Japan; www.chisso.co.jp) has established a new joint-venture (JV) company to produce solar grade silicon using a new process that was first developed by Chisso and subsequently refined, jointly, by the three JV partners: Chisso (50% share), Nippon…
Chementator: Plastics: A New Use for an Ethanol Coproduct
Corn residue left in fermenters after ethanol production could find a future use as a filler in plastics through research being done at the U.S. Dept. of Agriculture’s North Central Agricultural Research Laboratory (Brookings, S.D.; www.ars.usda.gov). The granular residue, called…
Chementator: More H2 from H2O
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…
Chementator: Monitoring Fermentation
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…
Chementator: A New Valve Seat
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…
Chementator: Tiny Buckyball Crystals
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…
Chementator: Carbon-Capture Market
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…
Chementator: EPA Delays GHG Action
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…
Chementator: PEEK Bioreactor Parts
The high salt concentrations, extreme pH values and high temperatures required in biotechnological research on extremophiles and marine organisms cause corrosion in the stainless-steel components of common fermenters. To enable further process development in these areas, Bioengineering AG (Wald, Switzerland;…
