One of the challenges for biofuels manufacturing is reliably feeding low-density feedstocks into high-pressure reactors, because it is difficult to feed agricultural and forest residue, as well as municipal solid waste, into pressurized systems without bridging, compaction and flow instability.…
The nanomaterial graphene oxide (GO) has been investigated as a way to improve concrete strength, but reported results of GO’s effects have been inconsistent and detailed understanding of the mechanisms of its strength-enhancing effects has been elusive. New studies by…
Disposable baby diapers are a challenging waste stream, because the absorbent polymers, non-woven fibers and organic material prevent them from mechanical-recycling processes. However, a three-way partnership has demonstrated a circular system for chemical recycling of disposable diapers. The project, involving…
Hydrogen production is expanding across the globe, but hydrogen gas remains difficult and costly to store and transport, restricting its broader use. A pilot project in Germany is demonstrating for the first time a salt-based process for long-term hydrogen storage.…
An ongoing large-scale demonstration project in Australia is the world’s first to apply a foam-fractionation technology to remove per- and polyfluoroalkyl substances (PFAS) in a sewage-treatment plant. The Surface-Active Foam Fractionation (SAFF®) technology developed by EPOC Enviro (Emu Plains, NSW,…
The production of salable co-products can substantially improve the economics for CO2 conversion processes. A new electrified thermochemical process developed by startup Reduciner Oy (Espoo, Finland; www.reduciner.com) combines captured CO2 streams with biochar to produce carbon monoxide, along with activated…
Researchers at the University of Birmingham (www.birmingham.ac.uk) have demonstrated a new production method for ultra-thin catalysts, unlocking new capabilities for the catalytic breakdown of persistent water pollutants. “The production method takes layered materials as the precursor, disperses them in a…
The leadership expert Ken Blanchard said “None of us is as smart as all of us” — a phrase that applies to Chemical Engineering's process of editorial decision-making. One source of intelligence is the CE Editorial Advisory Board. We have…
Plant Watch Air Liquide starts up CO2-capture pilot unit at Holcim cement facility June 11, 2026 — Air Liquide S.A. (Paris, France; www.airliquide.com) started up its first industrial-scale pilot unit specifically designed for the cement sector, based on its proprietary…
INEOS Enterprises announced the completion of the sale of INEOS Calabrian, its ultra-pure sulfur dioxide and derivatives business, to Ecovyst Inc. (Malvern, Pa.). The transaction, valued at $190 million, marks the successful conclusion of a strategic divestment first announced in…
