Using algae to clean wastewater
Technology developed by Algal Scientific Corp. (Northville, Mich.; www.algalscientific.com) uses algae to remove soluble organics, nitrogen and phosphorous from medium- to high-strength wastewaters in a single step. The technology is an alternative to multistep treatment processes involving the use of…
This PEM fuel cell has H2 storage built-in
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…
This demonstration plant makes bioethanol from tapioca residue
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…
June Chementator Briefs
Pilot bioreactor A next-generation photobioreactor is scheduled to be installed in June at the Orlando, Fla. pilot facility of biofeedstock company Proterro (Ewing, N.J.; www.proterro.com). Proterro is working with advanced fabrics and engineering firm ILC Dover (Dover, Del.; www.ilcdover.com)…
Recover waste heat with ORC technology
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,…
Tight-oil Tightrope for U.S. Refiners
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…
First in-situ refractive-index sensor for bioreactor monitoring
Process monitoring in biotechnology processes is critical to maximizing product yield and optimizing nutrient consumption. Startup company Stratophase Ltd. (Romsey, U.K.; www.stratophase.com) is now offering the first realtime, in-situ micro-optical sensor for monitoring and control of bioprocesses involving both microbes…
A new class of polymers that utilize CO2
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…
Biomass torrefaction plant undergoing expansion
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…
A copper catalyst with promise for utilizing CO2 in organic synthesis
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…
