Post-consumer absorbent hygiene products (AHPs), such as infant diapers, feminine hygiene products and adult incontinence products, present unique challenges for recycling, because they contain compound materials like superabsorbent polymers and non-woven fabrics, as well as bio-hazardous waste, which are difficult…
In late December 2025, a system that uses electric fields — rather than mechanical means — to generate nanometer-sized gas bubbles entered operation at a commercial site in Saudi Arabia. The nanobubble-generating technology was developed by the startup company AquaB…
Diagnostics, self-monitoring and digital communication detect flowmeter issues, provide insight Accurate flow measurement is the backbone of chemical process optimization. Today’s flowmeters are being enhanced with smart technologies and other advances designed to overcome flow monitoring challenges in the chemical…
Electrochemical water-treatment technologies facilitate the adsorption of ions, effectively removing contaminants such as calcium, magnesium, bromine and more. Such processes, however, are often hampered by the high costs associated with electrode regeneration and the use of ion-exchange membranes. A new…
Buildings lose considerable heating and cooling energy through their windows, so window coatings with low thermal conductivity would improve efficiency. However, finding insulating materials that are also transparent is a challenge. A team of researchers at the University of Colorado…
Variable-frequency drives designed for ease-of-use The EZ VFD® family of variable-frequency drives (photo) for¼- to 2-horsepower (hp) applications are feature-rich models designed for ease of installation and usage. They are plug-and-play for most applications and include easily adjusted trimpots for…
Ozone is seen an a safer and more environmentally friendly alternative to chlorine for water disinfection, but the efficient generation of ozone on-demand and at commercially relevant scales has been hindered by catalytic degradation problems. A team of researchers from…
A new structural material builds upon the promise of enzyme-enhanced CO2 mineralization to overcome decarbonization challenges in the construction industry. Researchers from Worcester Polytechnic Institute (WPI; Worcester, Mass.; www.wpi.edu), led by Nima Rahbar, head of WPI’s Department of Civil, Environmental…
The rise of artificial intelligence (AI) and high-performance computing (HPC) technologies has presented the chemical process industries (CPI) with opportunities for improving process efficiency, asset maintenance, product development and plant safety. While not fully realized in the CPI, the potential…
The chemical and physical properties of some solid materials render them prone to restricted flow and flow stoppages when discharging from bins and hoppers. This one-page reference outlines common solids-flow problems, as well as strategies and devices that can aid…
