The main mineral component of our bones and teeth — hydroxyapatite [HAP; Ca10(OH)2(PO4)6] — has been used by a Chinese team to develop a highly flexible paper with high antibacterial activity. The paper, made from silver nanoparticle-decorated ultra-long HAP nanowires…
Last month, Clariant AG (Muttenz, Switzerland; www.clariant.com) said that the pilot plant of a new process for making substitute natural gas (SNG) has been successfully tested, signifying that the technology is ready for commercial application. The process, called Vesta Once-through…
The Dow Chemical Co. (Midland, Mich.; www.dow.com) recently announced that it has completed validation of a new plastic film technology that can be recycled in existing processes for flexible polyethylene (PE) packaging, but that also performs well as an oxygen…
Each year, a large amount of plastic waste is generated, with 60% of the total plastic content of municipal solid waste composed of high-, low- and linear-low density polyethylene (HDPE, LDPE and LLDPE) and polypropylene (PP). Existing methods for degrading…
Making more ARA Arcadia Biosciences Inc. (Davis, Calif.; www.arcadiabio.com) and Dupont Pioneer (Des Moines, Iowa; www.pioneer.com) recently completed field-trial validation for new safflower plants that produce high levels of arachidonic acid (ARA) oil, a high-value, specialty nutritional oil. The field…
Colloidal glasses develop structural color through constructive interference. The color can be tuned by adjusting interparticle distance, making the colloidal glasses attractive for use as color pigments for use in coatings, displays, colorimetric sensors and optical barcodes. While colloidal crystals…
Computational technology from Arzeda Corp. (Seattle, Wash.; www.arzeda.com) can streamline the development of novel enzymes, as well as improve existing enzymes, for industrial fermentation. The company’s proprietary computational platform, known as Archytas, uses advanced algorithms to design and screen a…
Last April, a demonstration plant started up for the production of hydrogen from aluminum-based composite waste. The startup marks the culmination of a project, supported by NEDO, in which Alhytec Inc. (Takaoa City, Japan; www.alhytec.co.jp) developed the process to separate…
Last month at the IFAT trade fair (May 30–June 3; Munich, Germany), Huber SE (Berching: www.huber.de) and Microdyn-Nadir GmbH (Wiesbaden, both Germany: www.microdyn-nadir.de) unveiled a rotating membrane bioreactor (MBR) that utilizes membrane laminate technology. “By combining our two technologies we…
By the end of this year, a demonstration plant will start up in the U.S. that uses an electrochemical process to recover phosphorus from wastewater, producing a fertilizer as struvite (NH4MgPO4·6H2O). Although the location and capacity of the plant has…
