A device for the mass production of lactic acid oligomers, polylactic acid (PLA) and other polymers has been developed by Japanese researchers from the Renewable Plastics Group of the Research Institute for Innovation in Sustainable Chemistry, National Institute of Advanced…
Haldor Topsøe (Lyngby, Denmark; www.topsoe.com) will demonstrate a new technology that converts wood to liquid fuels, as part of a $25-million project funded by the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov). Among the partners in the project are…
Aiding crystal growth Scientists at Brookhaven National Laboratory (BNL; Upton, N.Y.; www.bnl.gov) have patented a method for absorbing hydrogen fluoride gas to enhance crystal growth. HF is commonly added to precursors to transfer crystalline order from a substrate to…
The power of osmosis Last month, Statkraft (Oslo, Norway; www.statkraft.com) opened what is claimed to be the world's first osmotic power plant. Although the prototype is very small (designed for 10 kW), the company believes data gained from the…
A multi-stage wet scrubber that combines the removal of sulfur, hydrogen chloride, sulfuric acid mist (SAM) and particulate matter (PM) in a single unit has reduced sulfur dioxide emissions by an average of 99.7% in its first large-scale commercial installation…
Changes in the rate of corrosion in water tubes have been detected within minutes by an externally mounted monitor developed by the Center for Nuclear Energy Research (CNER, Fredericton, NB, Canada; www.unb.ca/cner). The data were obtained in online tests over…
A process that produces 75–85 gal of ethanol per dry ton of mixed cellulosic waste feed will be commercialized by BlueFire Ethanol (Irvine, Calif.; www.bluefireethanol.com). The plant, to be built in Lancaster, Calif., will convert 130 dry ton/d of feed…
Haldor Topsøe A/S (Lyngby, Denmark; www.topsoe.com) has signed a design contract with an undisclosed client in China for a new plant that will produce substitute natural gas (SNG). When the plant comes on stream in 2011, it will produce close…
Incineration is becoming the only viable method for sewage sludge disposal as landfilling or spreading sludge onto farmland is no longer permitted in some countries. Today, sludge is commonly incinerated in large, centralized incinerators or as an additive in coal-fired…
Last month, a photocatalytic water-cleaning system that removes organic and inorganic contaminants that are difficult to breakdown from wastewater was inaugurated at the German Aerospace Center (DLR; Stuttgart; www.dlr.de) facility in Lampildshausem. The so-called RayWOx system features a new type…
