Cost-effective LGF-PP process
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…
Chementator Briefs
Cotton dyes Cotton Inc. (Cary, N.C.; www.cottoninc.com) and Archroma (Reinach, Switzerland) have collaborated to present what they believe is the first ever dye derived from cotton-plant residues. EarthColors is Archroma’s method of creating dyes in warm, ternary shades from natural…
Ethanol from CO2
Scientists at the U.S. DOE’s Oak Ridge National Laboratory (ORNL; Tenn.; www.ornl.gov) have developed an electrochemical process that directly produces ethanol from CO2. The researchers used a catalyst consisting of copper nanoparticles embedded in carbon spikes, and applied voltage to…
Commercial MOFs on the horizon
A partnership between materials company NuMat Technologies (Skokie, Ill.; www.numat-tech.com) and The Linde Group (Munich, Germany; www.the-linde-group.com) is set to bring metal-organic-framework (MOF) materials into the mainstream industrial-gas sector. Touted for their extremely high surface area and adsorption capacity, MOFs…
Plasma oxidation disinfects water without the addition of chemicals
A new technology that uses plasma to kill bacteria and simultaneously oxidize organic material in water systems offers a non-chemical alternative to water treatment in several industry sectors, such as food and beverage, power generation, oil and gas and others.…
Tin-based catalyst for photodecomposition
Daylight-driven photocatalysts have attracted much attention in the context of “green” technology for reducing pollutants. Although a number of active materials have been reported and their applications are rapidly increasing, many are discovered after enormous experimental efforts. Now, Isao Tanaka…
Making ammonia at milder conditions
Ammonia is a crucial chemical feedstock for fertilizer production, as well as a potential energy carrier. However, the current, century-old method of synthesizing ammonia, the Haber–Bosch process, consumes a great deal of energy, operating at high pressures (several hundred atmospheres)…
This desalination process uses much less energy than RO
An adsorption desalination and cooling (ADC) plant has been implemented at Solar Village near the Saudi Arabian capital of Riyadh, by King Abdulaziz City of Science and Technology (KACST; www.kacst.edu.sa). The project to build the plant resulted from a collaboration…
This alkylation process uses an ionic liquid catalyst
A new alkylation technology that uses ionic liquids as a catalyst has been licensed by Honeywell UOP (Des Plaines, Ill.; www.uop.com), and will be marketed under the tradename Isoalkyl. The technology — developed by Chevron U.S.A. Inc., a subsidiary of…
Recycling textiles into reusable cotton, polyesters and silver
Millions of tons of cotton-polyester-blend material that would normally be discarded in landfills could be recycled using a newly patented method for removing dyes from textiles, separating cotton from fabric blends, and depolymerizing polyesters. The process, developed and demonstrated by…
