Recycling rates for post-consumer textile waste are very low (<0.5%) because the fabrics often consist of tightly interlaced synthetic and natural fibers that require costly sorting and separation processes, and because they often contain dyes and additives that must be…
Electrolyzers are the key technology for producing “green” hydrogen using renewable energy. However, a new reactor platform aims to facilitate electrolysis without the need for any external electricity. The Electroless Coupled Exchange Reduction Oxidation technology platform (eXERO), developed by Utility…
Co-fermentation processes that can consume both sugars and CO2 are emerging as a promising technology to enhance product yield and reduce emissions in biofuels production. A team of scientists at Oklahoma State University (Stillwater, Okla.; www.okstate.edu) are working to accelerate…
The purchase price of an electric motor is generally thought to end up as a small fraction (2–3%) of the motor’s total lifetime cost, with the majority of costs resulting from the electricity used by the motor. This makes motor…
Reducing carbon dioxide emissions has taken center stage in efforts to reduce concentrations of greenhouse gases in the environment. Much effort is going into limiting the use of fossil fuels through increased use of renewable energy sources, switching to alternate…
Methane pyrolysis catalyst Catalytic methane pyrolysis (CMP) is an attractive route to producing hydrogen, because rather than generating CO2, the process produces solid carbon, which can be made in valuable forms that could offset the cost of hydrogen production. However,…
Using halide perovskites for photovoltaic (PV) solar-energy cells could dramatically reduce production costs compared to silicon-based PV cells, because perovskites are solution-processible at relatively low temperatures. However, long-term stability of these materials has been a significant challenge. Now, a research…
PPG (Pittsburgh, Pa.) announced that it has reached a definitive agreement to sell its silicas products business for approximately $310 million in pre-tax proceeds to QEMETICA S.A., a Warsaw, Poland-based, privately held manufacturer of soda ash, silicates and other specialty…
Green hydrogen company Lhyfe (Paris, France), OX2 (Stockholm, Sweden), one of Europe’s largest onshore wind developers, and green-fertilizer firm Velarion Group are joining forces to create a hydrogen-based industrial cluster in the Ånge municipality in Sweden. This project, situated in…
Evonik Industries AG (Essen, Germany) announced that its expansion of MetAMINO (DL-methionine) production facilities in Singapore has been completed. The MetAMINO production on Jurong Island is again running at full capacity, after shutdowns in Q4/2023 and Q2/2024. The production capacity…
