Outotec Oyj (Espoo, Finland; www.outotec.com) has developed a new chloride-based leaching process for recovering nickel from nickel matte — a commercial intermediate product of nickel smelting that contains about 65% of nickel. Developed since the 1980s, originally for Cu recovery…
A new remediation approach for industrial heavy-metal waste has been developed by Lewis Environmental Services, Inc. (LES; Pittsburgh, Pa.; www.lesvc.com). The patented Enviro-Clean process adsorbs heavy metals from liquid waste streams onto a bed of specially treated granular activated carbon.…
Advance in UF module The latest offering of ultrafiltration systems from Evoqua Water Technologies (Alpharetta, Ga.; www.evoqua.com) incorporates an advanced polyvinylidene fluoride (PVDF) membrane into a hydraulically balanced, modular filtration system. Known as Memcor CPII, the product employs a…
A Korean team has developed a carbon material that is as effective as graphene in applications, such as solar cells and semiconductor chips, using a process that requires only two steps instead of the usual eight. High-quality graphene is usually…
Scientists at the National Energy Technology Laboratory (NETL; Morgantown, W. Va.; www.netl.doe.gov) have demonstrated a process for enhancing the efficiency of the water-gas shift (WGS) reaction. The process revolves around a magnesium hydroxide sorbent material that can remove CO2 from…
The potential usefulness of 1,1-di-substituted alkenes for making performance polymers has been recognized for some time, but commercialization has been elusive because of the reactive nature of the monomers. Startup company Sirrus Inc. (Loveland, Ohio; www.sirruschemistry.com) has developed technology to…
A less expensive process for producing biodegradeable polyhydroxyalkanoate (PHA) plastics from renewable feedstocks is being scaled up by a factor of six, resulting in a 30,000–60,000-lb/mo pilot facility. The improved PHA process — developed by Meredian Inc. (Bainbridge, Ga.; www.meredianpha.com)…
New bio-based polyimides (PIs) that withstand temperatures up to 390°C — the highest ever reported for a bioplastic — have been developed by Tatsuo Kaneko at the Japan Advanced Institute of Science and Technology (JAIST, Nomi City; www.jaist.ac.jp), in collaboration…
A new thermoset polymer has been discovered by researchers at IBM Research Almaden (San Jose, Calif.; www.research.ibm.com). The new material, polyhexahydrotriazine (PHT), has a very high Young’s Modulus (up to 14 GPa, compared with a Young’s Modulus of 4 GPa…
NEC Corp. (Tokyo, Japan; www.nec.com) has developed a two-stage, heterogeneous synthesis for making a high-functionality bioplastic (70 wt.% plant content) from non-edible plant cellulose. The new bioplastic is said to have excellent thermo-plasticity (275 MFR), heat resistance (140°C glass transition…
