Electrochem Technologies & Materials Inc. (Montreal, Canada; www.electrochem-technologies.com) has recently patented a process for recovering rare-earth elements (REEs) from mercury phosphor powders — a byproduct from recyclers of fluorescent lamps and light bulbs. This technology offers a sound and profitable alternative for the production of REEs compared to the mining of low-grade ores, which...

With a separate algae-based technology, Algal Scientific has invented a sterile fermentation process for making beta-1,3-glucan from algae that has lower costs than those associated with fermenting the molecule with yeast. Beta-1,3-glucan is a polysaccharide that boosts immune-system function in humans and livestock animals. As a feed supplement, beta-glucan can eliminate the use of antibiotics as growth...

Conventional hydrogen-based systems designed to store electrical energy (from solar arrays, for example) typically feed electricity to a proton-exchange-membrane (PEM) electrolyzer to generate H2 from water. This H2 is then compressed and stored in a cylinder, or as a metal hydride in a canister containing a powdered metallic alloy. When electricity is required, H2 is supplied from the storage cylinder to...

In April, a demonstration plant started up that makes bioethanol from cassava residue — a byproduct of tapioca production. The demonstration plant, located at the cassava starch plant of EBP Ethanol Co. in Sa Kaeo Province, Thailand, is part of a four-year, $7-million project of New Energy and Industrial Technology Development Organization (NEDO) and Thailands National Innovation Agency. The project...

Last April, Siemens Energy (Erlangen, Germany; www.siemens.com/energy) introduced the Siemens organic Rankine cycle (ORC) modules, which enable operators of industrial plants to generate power from low-temperature (around 300°C) waste heat. Unlike a conventional Rankine cycle, which converts water to steam, the ORC vaporizes an organic fluid with a high molecular weight. The organic fluid has a boiling...

A new plastic made from CO2 and butadiene has been synthesized by Kyoko Nozaki and her research group at the University of Tokyo (Tokyo, Japan; www.chembio.t.u-tokyo.ac.jp/labs/nozaki). Although butadiene is already produced on a large scale for making synthetic rubber, it has previously been impossible to copolymerize CO2 and butadiene in a single-step reaction, because the...

A biomass torrefaction plant run by New Biomass Energy LLC (NBE; Quitman, Miss.; www.newbiomass.com) is currently undergoing an expansion that will increase its annual production capacity to 250,000 tons of torrefied wood product. The company expects the expansion to be completed by the end of 2014, says Alison Hunt, NBE’s VP of development. Torrefaction is the process of roasting wood or other...

Scientists from the A*STAR (Agency for Science, Technology and Research) Institute for Chemical and Engineering Sciences (Singapore; www.a-star.edu.sg) have shown that a copper catalyst can incorporate CO2 into organic molecules under mild conditions, opening the way to an inexpensive, nontoxic source of carbon for the synthesis of products such as plastics and pharmaceuticals. Normally, a lot of energy is...

North American production of crude oil, driven by a rapid increase in output of “tight oil” from U.S. shale deposits like Bakken and Eagle Ford, is surging. In many, but not all areas, petroleum refiners are incorporating an increasing amount of this cost-advantaged feedstock into their crude-oil-processing slates to capitalize on its discounted price, which is partly a result of a lack of...

A newly developed proprietary terpolymer from GE Water and Process Technologies (Trevose, Pa.; www.gewater.com) has been shown to provide improved scale control on heat-transfer surfaces in low- to intermediate- (up to 900 psig) pressure-steam boilers. Deposit formation on heat-transfer and steam-generating surfaces can result in reduced boiler efficiency and tube failures. Known as Solus AP, the GE...
