TPA from PET bottles A chemical method previously developed for recovering monomers from polyester blend fabrics and textiles has now been adapted for use with waste plastic bottles made from polyethylene terephthalate (PET). The BCD Group (Cincinnati, Ohio; www.bcdinternational.com) developed…
Sunvapor Inc. (Livermore, Calif.; www.sunvapor.net) was awarded a grant from the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov) last month to scale up its Green Parabolic Trough Collector, a solar thermal technology that cuts construction costs by half compared…
Flexible micro light-emitting diodes (LEDs) — a sub-100-µm light source for red, green and blue light — have become a strong candidate for the next-generation display due to their low power consumption, fast response, and flexibility. The previous micro-LED technology…
Last month, MOL Group (Budapest, Hungary: www.mol.hu) entered into a strategic partnership with Inovacat (Amersfoort, the Netherlands; www.inovacat.com) to further upscale and commercialize Inovacat’s Gasolfin gasoline-to-olefins technology, which converts low-valued gasoline and naphthas into high-value propylene, butylene and BTX (benzene,…
Nordic Blue Crude A/S (NBC; Porsgrunn, Norway; www.nordicbluecrude.no) intends to build the first power-to-liquids (PtL) plant in the Norwegian industrial park of Heroya, located 140 km southeast of Oslo. Although the date for the startup has not yet been released,…
Each year, more than 1 billion automobile tires are replaced worldwide. Together, the used tires contain 4.4 million metric tons of valuable products, such as carbon black, metals, fuels and chemicals. In an effort to recover these materials, the University…
Amine-containing solids have been investigated as promising adsorbents for CO2 capture, but existing amine-containing adsorbents degrade by oxidation, making them unreliable for repeated CO2 adsorption-desorption cycles over a long period. The low stability requires the continuous addition of fresh adsorbents,…
Forward Osmosis Last month, Bioindustrial Innovation Canada (BIC; Sarnia, Ont.; www.bincanada.ca), Forward Water Technologies (FWT; www.forwardwater.com) and GreenCentre Canada (GCC; Kingston, Ont.; www.greencentrecanada.com) announced a private investment into FWT, supporting the commercial scaleup of a proprietary forward-osmosis technology. The initial…
A filter for water purification that can replace, with a single step, the complex, time-consuming and multi-stage processes currently needed, has been developed by a team from CSIRO Manufacturing (Sydney, Australia; www.csiro.au), led by Dong Han Seo. The team has…
Many methods have been developed to remove spilled oil and organic pollutants from water, but they all entail shortcomings, such as low absorption ability and poor buoyancy. Now, a team from the School of Light Industry and Chemical Engineering, Dalian…
