The release of silver from industrial wastewater has caused serious environmental problems. Many methods have been developed to remove silver ions from industrial wastewater, including chemical precipitation, ion exchange, electrolysis, replacement, membrane and reverse osmosis. Several adsorbents have been used…
A new commercial manufacturing process for carbon nanotubes (CNTs) produces tubes in the range of 1–10 mm in length (5–12-nm dia.), two orders of magnitude longer than currently available CNTs, which typically have lengths from 5–20µm. “Despite attractive mechanical and…
Gas Innovations (La Porte, Tex.; www.gasinnovations.com) has signed a 15-year, pay-per-use agreement with Haldor Topsøe A/S (Topsøe; Lyngby, Denmark; www.topsoe.com) for a second on-site carbon-monoxide production unit, using Topsøe’s electrolytic Carbon Monoxide solution (eCOs) technology. The first eCOs unit in…
The Karlsruhe Institute of Technology (KIT; Germany; www.kit.edu) is cooperating with research institutions and industry partners to develop a novel process chain for the synthesis of methanol, either without the use of fossil resources or by reusing CO2 from undesired…
A group of organizations, lead by the Southwest Research Institute (SWRI; San Antonio, Tex.; www.swri.org) has begun a project to design a power-generation pilot plant featuring a flameless, pressurized oxyfuel combustion technology that allows the capture of 100% of the…
Starch is essential for imparting strength to corrugated cardboard boxes, but millions of tons of starch are lost in cardboard recycling processes annually because conditions are ripe for bacteria to thrive, and the microorganisms degrade starch by converting it to…
A new process for making long glass fiber polypropylene (LGF-PP) concentrates (glass-fiber-containing plastic pellets) allows a higher glass-fiber content than is possible with conventional processes. Plastics maker Trinseo (Berwyn, Pa.; www.trinseo.com) has developed the process, which is capable of making…
Bio foam control Last month, Novozymes A/S (Bagsvaerd, Denmark; www.novozymes.com) introduced Fermax, an enzyme protease that prevents foam development during the sugarcane ethanol fermentation process, while delivering improved control and replacing chemicals. For an average size plant, trialing partners experienced…
Scandium International Mining Corp. (Sparks, Nev.; www.scandiummining.com) is about to become the first company to achieve production from a primary scandium mine, with its project near the small town of Nyngan, New South Wales, Australia. The production of scandium from…
Demand for carbon fiber (CF), which can be used to make strong, lightweight composite materials for improving vehicle fuel economy and wind-power generation, has been growing. However, widespread use of these advanced composites has been limited by the high production…
