Many wastewater-treatment plants rely on iron-based coagulation to remove phosphorus from water. Following treatment with iron-based coagulants, most iron present in the sewage sludge is in the form of an iron-phosphate mineral known as vivianite. A patented technology called ViviMag…
Hydrogen fuel cells, which use hydrogen and oxygen to generate clean electricity and pure water, are considered among the most promising clean energy sources. However, the accumulation of liquid water inside hydrogen fuel cells is a major roadblock to efficient…
Demand for synthetic graphite, a top-priority critical material in the U.S., is increasing because of its use in lithium-ion battery anodes and in steel-making. To meet the increased demand, while also cultivating a domestic source of synthetic graphite (most of…
Batteries with solid-state electrolyte materials, rather than liquids or gels, are a goal of technology developers because of their advantages for battery safety, durability and reduced charge times. Certain ceramic-based electrolytes have shown the ability to transport ions quickly, but…
The final investment decision (FID) for a plant in Baytown, Tex. that will convert polyolefin waste into fuels and petrochemical feedstocks is anticipated near the end of 2026. The facility, operated by Abundia Global Impact Group Inc. (AGIG; Houston, Tex., www.abundiaimpact.com),…
A team of researchers at the Korea Research Institute of Chemical Technology (KRICT; Daejeon, South Korea; www.krict.re.kr), along with industry partners, has developed catalyst and process technology that converts carbon dioxide into liquid hydrocarbons, such as gasoline and naphtha, without…
Lubrizol (Cleveland, Ohio; www.lubrizol.com) recently began producing chlorinated polyvinyl chloride (CPVC) resin in commercial reactors equipped with light-emitting diodes (LEDs) as the light source, instead of the conventional mercury lamps. The company’s LED reactor technology enhances the thermal stability of…
Direct battery-recycling methods, such as re-lithiation — where depleted lithium is replenished directly onto cathodes via a solid-state reaction — hold many benefits over indirect methods, such as those relying on hydrometallurgy or pyrometallurgy, where cathodic structures are destroyed in…
Lithium-iron-phosphate (LFP) batteries offer a compelling combination of performance characteristics for stationary energy storage, including improved safety and longevity, when compared to other lithium battery chemistries, such as nickel- and cobalt-based formulations. However, there are limited recycling pathways dedicated to…
Synthesis of methanol from carbon dioxide is among the key goals for net-zero-CO2 production of chemicals and fuels. Previous investigation has suggested that indium oxide could serve as an effective catalyst for this reaction, but the structural details of the…
