Ultra-rapid electron curing streamlines electrode manufacturing

A new electron-curing system has demonstrated a high-speed, solvent-free production process for powerful battery electrodes at industrial scale. The production process, operated by Kodak Co. (Rochester, N.Y.; www.kodak.com) using the RaiCure™ platform developed by Ateios Systems Inc. (Newberry, Ind.; www.ateios.com),…

Novel electrolyzer reshapes power conversion and efficiency for green-hydrogen production

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…

Considerable scaleup underway for continuous carbon-fiber recycling

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…

“Chemical sorting” process improves separation rate of solid contaminants from automotive waste

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;…

First continuous and scalable ambient pathway to electrically conductive plastics

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…

Improved version of PFAS capture-and-destruction technology commissioned in Germany

Following regulations for drinking water, increasingly stringent limits for per- and polyfluoroalkyl substances (PFAS) in industrial wastewater are anticipated, necessitating improved technology to handle higher rates of removal, as well as to destroy the compounds in concentrated samples. Gradiant (Boston,…

CO2-utilization technology makes renewable acrylonitrile

Nearly all of the currently produced building-block chemical acrylonitrile (AN) results from the ammoxidation of propylene, a process that requires precise heat control and generates several toxic side products, such as hydrogen cyanide. The startup company Mars Materials (Houston, Tex.;…

Novel PVC-recycling process piloted in Ohio

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…

Fibrous MOFs significantly accelerate CO2-adsorption kinetics

Solid adsorbents, including metal-organic frameworks (MOFs), have shown great promise in carbon-capture applications as an alternative to traditional amine-based processes. Typically, adsorbent materials are manufactured as powders and converted into beads or pellets to make them more suitable for large-scale…

Destroy PFAS and remove perchlorate in a single process

A new water-treatment process is said to be the first to comprehensively destroy per- and polyfluoroalkyl substances (PFAS) while also eliminating perchlorates. The PFASER technology, developed by WSP Global (Montreal, Que., Canada; www.wsp.com) is an advanced electro-oxidation (EO) treatment system…
