A “plug-and-play” microbial technology enables the recovery of additional copper from low-grade ores when used alongside traditional sulfuric-acid heap-leach methods. Working synergistically within the existing heap-leach infrastructure, the unique microbial communities that have been cultivated by Endolith (Westminster, Colo.; www.endolithmining.com)…
Water contamination from per- and polyfluoroalkyl substances (PFAS) compounds is one of the most significant environmental and health issues globally. In particular, effectively breaking the carbon-fluorine bonds that are paramount to the stability and persistent nature of PFAS is extremely…
The market for lithium-ion batteries continues to grow, driven by demands for consumer electronics, renewable energy storage and electric vehicles. The manufacture of these batteries is itself energy-intensive, with production steps that typically involve creating a slurry for a wet-coating…
Thin-film polymer membranes have been very effective for industrial-scale desalination of seawater, but have not been used for separation of liquid hydrocarbon mixtures because oil-separation membranes tend to absorb oil components and swell, which eliminates their size-sieving ability to separate…
Operations are planned to start up soon at a first-of-its-kind recycling demonstration plant in Monthey, Switzerland. Employing a proprietary reaction technology developed by DePoly S.A. (Sion, Switzerland; www.depoly.co), the plant is set to treat up to 500 tons/yr of polyethylene…
The CO2 electrochemical reduction reaction (CO2RR) has intrigued scientists for decades as a way to make fuel and chemicals from the greenhouse gas CO2. Prior research identified copper as a CO2RR catalyst, and has revealed the active sites where electrocatalysis…
One method used to deliver drugs in a controlled manner is to encapsulate them in an injectable gel. Microgels — hydrogel particles made of synthetic or natural polymers with a high water content that measure about 1 to 100 micrometers…
Recycling vehicle tires is complicated because the rubbers used (including butadiene and polyisoprene) are highly cross-linked, and because pyrolysis-based recycling of the rubbers generates environmentally hazardous compounds like benzene and dioxins. Now, researchers at the University of North Carolina at…
As industries and consumers have shown an increasing preference for water and oil repellents that do not include any fluorinated materials, significant efforts and years of research and testing have gone into developing non-fluorinated alternatives. AGC Chemicals Americas, Inc. (AGCCA;…
Safe and cost-effective storage represents one of the major hurdles in the widespread adoption of “clean” hydrogen in energy applications. A hydrogen-storage approach called cryo-compression is being poised as a bridge between high-density (but expensive) hydrogen liquefaction and cheaper (but…
