Circular-loop recycling for disposable baby diapers demonstrated in Europe
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…
Pilot project debuts integrated hydrogen storage and transport using aqueous-salt technology
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.…
World-first sewage-treatment trial proves comprehensive dual-phase PFAS removal
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,…
Electrified process converts CO2 and biochar into industrial products
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…
Atomically thin photocatalysts unlock new pollution-degradation capabilities
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…
