Tire recycling The Mitsubishi Chemical Group (MCG; Tokyo, Japan; www.mcgc.com) has demonstrated chemical recycling of end-of-life tires (ELTs) using the coke ovens at its Kagawa Plant (Sakaide City, Kagawa Prefecture). The company is able to feed crushed ELTs as raw…
Industrial electrolysis involves passing a direct electric current through an electrolyte to elicit a range of chemical reactions. Electrolyzers are key pieces of technology for producing many important industrial chemicals. This one-page reference reviews the basic general operation of an…
As wind energy takes a prominent role in the energy transition, researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL: www.nrel.gov) have focused on manufacturing sustainable turbine blades that can be made from bio-derivable resources and then…
Last month, the U.S. Department of Energy (DOE, www.energy.gov) announced that two Energy Innovation Hub teams would receive a total of $125 million ($62.5 million to each team) in funding over five years to “seed and accelerate next-generation technologies beyond…
A significant contributor to the cost, energy consumption and carbon footprint of silver production is in the refining steps to remove, recover and recycle zinc from Parkes Crust silver-zinc intermetallic compounds. A fundamental redesign of the silver process to improve…
Currently, medical waste streams are complicated to recycle because these single-use products — such as facemasks, syringes, nitrile gloves and non-woven gowns — consist of multiple materials and must be considered contaminated with potentially infectious particles. Now, researchers at Chalmers…
This compressor extends horsepower and flow range The newly launched SFC 110M variable-frequency-drive compressor (photo) extends the SFC product series to 150 hp, with a 110-kW permanent-magnet motor, and enhances the flow range up to 742 ft3 /min at 100…
Seemingly small component changes can make a large impact on the productivity of electrochemistry systems, such as electrolyzers used for producing “green” hydrogen. For example, a new coating technology developed by Oxford nanoSystems Ltd. (OnS; Abingdon, U.K.; www.oxfordnanosystems.com), when applied…
Metal-organic frameworks (MOFs) have shown great potential for a number of applications, including as carbon-capture materials, but their use commercially has been limited by production methods, which are generally expensive batch processes. With the development of a continuous process for…
Plant Watch SK Energy to start commercial production of SAF September 16, 2024 — SK Energy, a subsidiary of SK Innovation Co. (Seoul, South Korea; www.skinnovation.com), announced the completion of South Korea’s first dedicated production line for sustainable aviation fuel…
