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 distiller’s dried grains (DDGs), is now used mainly for animal feed. Plastics would provide an additional market...

  Much as the chemical process industries (CPI) themselves are always evolving, so too are the engineering materials that play a role behind the scenes. While they may not always make headlines as groundbreaking scientific technologies tend to do, new and improved engineering materials are constantly emerging to enhance and advance the practice of chemistry. A few of the latest materials are...

Ethanol could be produced for less than $1/gal through a new process developed by ZeaChem, Inc. (Lakewood, Colo.; edlinks.che.com/7374-531). The company has piloted the process (flowsheet) and plans to start up a 1.5-million-gal/yr full-scale demonstration plant at the end of 2009, says Jim Imbler, chief executive officer. The process starts with acid hydrolysis of biomass to obtain sugars, as in standard...

Alkylglyceryl ethers (AGEs) are biodegradable nonionic surfactants with excellent foaming and moisturizing properties. Up to now, AGEs have been made in batch reactors whereby the corresponding alkyl glycidyl ether (GE) is hydrolyzed in a solvent (alcohol or ethyleneglycol monoalkyl ether) with a homogeneous acid or base as a catalyst. Such conventional routes leave catalyst residue and solvent in the product...

Current silks tend to lose performance in water and yellow in sunlight. Few of the silk-producing species of insect or spider are amenable to domestication, their silks are difficult to produce using biotechnology, and it is difficult to spin those recombinant silk proteins. The difficulty of reproducing those silks is due to factors...

Titanium, the ninth most abundant metal in the world, has some desirable properties — the highest strength-to-weight ratio of any metal and high-temperature and corrosion resistance. However, its high production cost has so far restricted its use mainly to aerospace applications. A combination of process steps that promises to cut the cost by 50% is being developed by Oak Ridge National Laboratory...
