This process can fully mineralize PFAS with no toxic byproducts
Breaking the stable carbon-fluorine bonds within per- and polyfluoroalkyl substances (PFAS) is one of the most significant challenges in mitigating persistent PFAS pollution. The Hydrothermal Alkaline Technology (HALT; diagram), invented at the Colorado School of Mines (Golden, Colo.; www.mines.edu) and…
Valves for use in Sanitary Processes and High-Purity Applications
Sanitary valves are essential for applications that demand product purity, process integrity and regulatory compliance. This article discusses valve types, working principles and components, and provides considerations for selection and specification Sanitary valves are essential components for applications in the…
Novel reactor addresses limitations of pyrolysis for plastics recycling
Pyrolysis has received much attention as a technology capable of breaking down waste plastics in recycling processes, but existing pyrolysis approaches often give rise to products with broad molar mass distributions and poor yields. Catalysts can improve yield and selectivity,…
Avenues for Decarbonizing the Steel Industry
Energy- and carbon-intensive, steel production is categorized as one of the most “hard-to-abate” industries, making the scaleup of decarbonization technologies crucial not only for steelmakers themselves, but for every downstream industry in the supply chain Responsible for some 9% of…
Switchable solvent supports freshwater extraction from hypersaline brine
Extremely high-salinity water streams present difficulties for many types of processing equipment, such as membranes and filters, and most commercial treatment methods involve thermal evaporators or crystallization, which are energy-intensive and require special anti-corrosion materials. A new membrane-less, non-evaporative process…

Plant Watch Chevron Phillips Chemical completes LV PAO expansion in Belgium August 12, 2025 — Chevron Phillips Chemical L.P. (CPChem; The Woodlands, Tex.; www.cpchem.com) has completed the expansion of its low-viscosity polyalphaolefins (LV PAO) production unit in Beringen, Belgium, significantly…
Carbon dioxide removal combined with desalination
Most existing carbon-dioxide removal (CDR) approaches have focused on air, but the volumetric concentration of dissolved inorganic CO2 in surface water is much higher (150X) than its concentration in the atmosphere. Removing CO2 from water could prove to be a…
Air Classification of Powdered Materials
Air classification of powdered materials offers a way to control particle size distribution in solids-handling operations. Information on key performance metrics and operating practices of size classification equipment is presented here The handling and processing of solid particulate materials are…
New reactor supports organic-assisted electrolysis for green hydrogen
The production of “green” hydrogen via electrolysis is seen as a key decarbonization pathway for certain industry sectors, but its efficiency can be hampered by a number of factors, including the accumulation of gas bubbles on electrode surfaces within electrolyzers…
World’s first grid-connected iron-air battery now operational in the Netherlands
The Netherlands-based startup company Ore Energy (Amsterdam, the Netherlands; www.oreenergy.com) recently announced that it has successfully connected its flagship iron-air battery system to the electric grid in the city of Delft, the Netherlands. It is the first iron-air battery system…
