Processes to reuse plastics from end-of-life vehicles are complicated by solid contaminants — including pre-embedded metal and rubber components of different sizes and reinforcing glass fiber. Currently, recycling solids-containing waste-plastic parts is accomplished by physical sorting processes. Honda (Tokyo, Japan;…
A hazardous-materials storage system with climate control The WHS hazardous-material storage system (photo) features intelligent air conditioning to combat extreme weather, and to allow storage of substances that must be stored under precise temperature conditions. The integrated heating and cooling…
Carbon-fiber reinforced plastics (CFRPs) are used in a broad range of products, including automotive parts, construction materials and many others. Economically recycling these materials has proven challenging due to their multi-material makeup. Typically, they are chopped into pellets or strips…
Plant Watch World-scale black pellet plant begins commercial operation in Vietnam October 14, 2025 — Idemitsu Kosan Co. (Tokyo; www.idemitsu.com) has commenced commercial operation of its newly constructed plant in Gia Lai Province, Vietnam, to produce black pellets (BP), a…
Eliminating the traditional electrolyte from electrolysis, a new electrolyzer design is aiming for higher efficiencies and lower costs in green hydrogen production. Tobe Energy (Oklahoma City, Okla.; www.tobe.energy) has developed a high-voltage all-stainless-steel electrolysis system that operates at much lower…
Polyvinyl chloride (PVC) is among the world’s most widely used polymers. Recycling PVC via mechanical and high-temperature chemical processes is challenging due to its chlorine content.The startup company Plastic Back (Tel Aviv, Israel; www.plastic-back.com) aims to raise the rates of…
Electrically conductive plastics, also known as conjugated polymers, bring many cutting-edge benefits for flexible sensors, medical devices, energy-storage systems and more. They are currently produced at relatively small volumes and come with extremely high prices. A novel technology discovered at…
Understanding the forces acting on agitator impeller blades during turbulent flow in a mixing vessel is essential for successful and efficient operation. Presented here is information on the hydraulic force, its source, and how to calculate it Mechanically agitated vessels…
As the hydrogen economy matures and production scales up, critical equipment like valves must evolve to ensure safe and optimized handling and transport According to the Energy Transition Council, the overall share of fossil fuels is expected to decrease significantly…
In October, the Royal Swedish Academy of Sciences awarded the 2025 Nobel Prize for chemistry to three pioneers who were instrumental in the development of metal-organic frameworks (MOFs). Richard Robson (University of Melbourne; www.unimelb.edu.au), Susumu Kitagawa (Kyoto University; www.kyoto-u.ac.jp and…
