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) — stems from a patent portfolio initially established by Proctor and Gamble. The microbial...

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 for typical polyimide thermosets), along with many other characteristics that make it a suitable thermosetting material. However, unlike...

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...

A new plastic made from CO2 and butadiene has been synthesized by Kyoko Nozaki and her research group at the University of Tokyo (Tokyo, Japan; www.chembio.t.u-tokyo.ac.jp/labs/nozaki). Although butadiene is already produced on a large scale for making synthetic rubber, it has previously been impossible to copolymerize CO2 and butadiene in a single-step reaction, because the...

A new process for producing monoethylene glycol (MEG) from synthesis-gas-based feedstocks is nearing completion of extensive pilot plant operation, according to developers Eastman Chemical Co. (Kingsport, Tenn.; www.eastman.com) and Johnson Matthey Davy Technologies Ltd. (London, U.K.; www.davyprotech.com). The technology enables MEG production from a variety of...

JX Nippon Oil & Energy Corp. (JX_NOE; Tokyo, Japan; www.noe.jx-group.co.jp) has demonstrated enhanced propylene and butenes yields by its high-severity, fluid-catalytic cracking (HS-FCC) technology. In a 3,000-bbl/d semi-commercial plant, which has been operating at the company’s Mizushima Refinery since May 2011, propylene yields have been...

Cationic polymers have been used in the petroleum industry as shale-control agents, demulsifiers, blocking agents, and filtrate reducers for drilling fluids, but process complexity and high cost have limited their application. Now researchers from Zhejiang Normal University (Jinhua; www.zjnu.edu.cn) and Shandong University (Jinhua, both China; www.sdu.edu.cn) have reported the preparation of a...

Newlight Technologies (Irvine, Calif.; www.newlight.com) has launched commercial production of a polyhydroxyalkanoate (PHA) thermoplastic made from air and greenhouse gases, such as methane, that can be manufactured less expensively than conventional petroleum-derived alternatives, using a novel high-efficiency biocatalyst and bioreactor system. While considerable effort has previously been directed toward...

A test method developed by SABIC (Saudi Basic Industries Corp.; Riyadh, Saudi Arabia; www.sabic.com) scientists drastically reduces the time needed to evaluate slow-crack growth resistance in high-density polyethylene (HDPE) that is used in pressure pipes. The strain-hardening test method allows HDPE producers to speed product development and improve quality control by offering an alternative to...
