Alkaline thermal process generates hydrogen fuel from mixed plastic waste
A team of researchers from the Ewha Women’s University (Seoul, South Korea; www.ewha.ac.kr) and the University of California at Los Angeles (UCLA; www.ucla.edu) have taken a step toward addressing one of the main challenges in plastics recycling — economically processing…
Extending the Life of Legacy Rotary Dryers
Rotary dryers are often in operation for many decades after their initial commissioning. This article provides a decision framework to consider whether to upgrade, repair or replace an aging rotary dryer Rotary dryers are fundamental to ensuring product quality and…
Printable gel electrolytes support bespoke battery architectures
Unlike conventional liquid electrolytes used in lithium-ion batteries, gel polymer electrolytes (GPEs) are immobilized within a polymer network, which reduces leakage risks, thereby improving mechanical and thermal stability. However, current methods for GPE fabrication result only in two-dimensional planar films,…
Novel microwave method reshapes thermal regeneration for direct-air CO2 capture
Many direct-air capture (DAC) technologies employ sorbent materials to remove CO2 from ambient air. These sorbents require periodic thermal regeneration — typically using steam — to release bound CO2. This thermal regeneration step is often the largest cost and energy…
A more straightforward condensation route from bioethanol to linear alcohols
Linear alcohols, such as butanol, hexanol and octanol are widely used in coatings, adhesives, surfactants, detergents, lubricants, cosmetics and many other products, as well as fuels. Typical industrial methods for producing these alcohols rely on fossil resources and low-selectivity mechanisms…
Electro-extraction technique unlocks copper in waste streams
Initiatives to increase electrification and build digital infrastructure for artificial intelligence are among the trends increasing demand for copper (and other critical materials), prompting efforts to identify new sources of the metal. The startup company SiTration (Watertown, Mass.; www.sitration.com), a…
Focus On: Laboratory Equipment
This X-ray fluorescence analyzer has sub-ppm sensitivity The ALTRACE is a benchtop energy-dispersive X-ray fluorescence (EDXRF) spectrometer (photo) designed for rapid, non-destructive elemental analysis across a wide range of sample types. Featuring sub-ppm sensitivity, it provides screening for elements from…
Show Preview: POWTECH TECHNOPHARM
From September 29–October 1, the bulk solids and conveying technology industry will gather at the Nuremberg, Germany exhibition center. Powtech Technopharm is a leading trade fair for processing and bulk-solids technology, drawing exhibitors from across the chemical process industries (CPI)…
Self-Neutralization of Nitric Acid Wastewater in a Wastewater Treatment Plant
Harnessing the alkalinity generation during denitrification in the treatment of acidic wastewater from a chemical-manufacturing facility in a wastewater treatment plant (WWTP) results in self-neutralization, offering cost savings and other benefits Facilities throughout the chemical process industries (CPI) produce large…
Eco-friendly method for making MOF-encapsulated enzymes expands possibilities
Enzyme-based biocatalysts are a key aspect of industrial green-chemistry initiatives, but they often don’t have the required stability to perform in industrial settings. A strategy for allowing enzymes to function longer and under harsher conditions has been to encapsulate them…
