In November 2023, the first commercial test was initiated for a novel, fouling-immune membrane for brackish-water reverse osmosis (BWRO) applications through an early-access program. Membrane developer ZwitterCo (Woburn, Mass.; www.zwitterco.com) says its membrane is fouling-immune in cases where fouling of…
One of the major hindrances in saltwater electrolysis for “green”-hydrogen production is the cost of materials to construct electrolyzer components that can withstand an extremely corrosive saltwater environment. Currently, titanium coated with platinum or gold is usually required for such…
An evolving threat landscape for plant security is attracting more attention to the development of operational technology (OT)-specific cybersecurity programs, underlining the importance of collaboration and blurring the line between cyber- and physical security Cybersecurity threats against critical infrastructure sites,…
Direct-air capture (DAC) of atmospheric carbon dioxide presents promise for helping to reach global-warming reduction goals. However, many DAC technologies are hindered by high costs and inefficiency. RepAir Carbon (Yokne-am Illit, Israel; www.repair-carbon.com) recently launched a field prototype of its…
In traditional beer brewing, the progress of the fermentation process is typically checked manually, by inserting a hydrometer (beer spindle) that measures the density, from which the extract content of the wort can be derived — a procedure that not…
Researchers at Eidgenössische Technische Hochschule Zürich (ETH Zurich; Switzerland; www.ethz.ch) and Nanyang Technological University Singapore (NTU; www.ntu.edu.sg) developed a process to utilize industrial chicken feathers for making proton-conductive membranes that can be used in fuel cells, protonic transistors and water-splitting…
A new ammonia-recovery plant has begun steady-state operation to demonstrate a patented process to upcycle the ammonia content from cattle manure into stabilized fertilizer ingredients. The Ammonia Recovery System (ARS) was developed by Bion Environmental Technologies, Inc. (Old Bethpage, N.Y.;…
A new plasma-based technology is being touted as a more sustainable method for textile finishing, including water-intensive dyeing and coating processes. The Ausora process, developed by Xefco Pty. Ltd. (Eveleigh, Australia; www.xefco.com), in partnership with the Recycling and Clean Energy…
Metal components made with laser powder-bed fusion — an important additive manufacturing process — must be qualified for use in critical applications, but the qualification relies on expensive non-destructive evaluation (NDE) techniques. In-process monitoring offers a less expensive alternative, but…
Leather Tanning Trumpler GmbH & Co. KG (Worms, Germany; www.trumpler.com) and Archroma (Pratteln, Switzerland; www.archroma.com) have developed a new leather-production process that can be used to produce high-performance leather in a more eco-friendly and cost-efficient way. The new process, DyTan,…
