The research group of professor Shiro Saka at the Dept. of Socio-Environmental Energy Science, Graduate School of Energy Science, Kyoto University (Kyoto, Japan; www.ecs.energy.kyoto-u.ac.jp) has developed a new process that efficiently produces bioethanol from non-edible lignocellulose resources, without generating carbon…
Mixtures of rare-earth metals (REMs) are notoriously difficult to separate, but a team of researchers from Harvard University (Cambridge, Ma.; www.seas.harvard.edu) has developed a method for efficiently extracting REMs with a high level of selectivity. By taking advantage of the…
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…
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…
Polylactic acid (PLA) is a versatile biopolymer, but its applications are somewhat limited due to its brittleness. Now, an alternative bio-based composite material has been developed that overcomes this limitation. Developed by the industry-university consortium of Hitachi Zosen Corp. (HITZ;…
A proprietary technology and patented process from GreenMantra Technologies (Brantford, Ont., Canada; www.greenmantra.ca) that produces synthetic waxes from underutilized plastic recycling streams, including films and bags, has reached commercialization. The company’s first industrial-scale manufacturing plant started up in May, and…
