Sewage and wastewater often contain pollutants and environmental hormones (endocrine disruptors) that can have a negative effect on the environment and on human health. Catalysts currently used to destroy such pollutants involve high costs. And up to now, research has…
Plant Watch Arkema to expand PVDF plant in Changshu October 15, 2019 — Arkema (Colombes, France; www.arkema.com) will increase the capacity of polyvinylidene difluoride (PVDF) at its Changshu, China plant by approximately 50%. The expanded capacity is scheduled to come…
To improve sustainability, materials manufacturers are welcoming new digital technologies and process innovations into their global supply chains From palm oil to plastics, the global supply chains of many critical raw materials are evolving as consumers and manufacturers increasingly seek…
Natural wax coating Researchers from Aalto University (Finland; www.aalto.fi) have developed a new way of making garments water-resistant, without using toxic chemicals. The treatment is non-toxic, and does not impair breathability. The coating uses carnauba wax from Brazilian palm-tree leaves.…
Researchers at the City University of New York Energy Institute (ccny.cuny.edu) have developed a low-cost battery based on manganese dioxide and zinc that reaches voltages of greater than 2 V, a first-time achievement that could allow batteries with these low-cost…
On September 19, Focus-On (Dordrecht, the Netherlands; www.focus-on-process.com) — a new, 50:50 joint-venture (JV) of Samson AG (Frankfurt am Main; www.samson.de) and Krohne GmbH & Co. KG (Duisburg, both Germany; www.krohne.com) — introduced its new “intelligent process node,” a device…
Scientists at Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg) have developed a device for atmospheric monitoring that can identify a wide range of airborne gases and chemicals instantly. The prototype device is portable and suitable for rapid deployment by agencies to…
Carbyne transfer Marcos G. Suero and his research group at the Institute of Chemical Research of Catalonia (ICIQ; Tarragona, Spain; www.iciq.es) have reported a new reaction that inserts a monovalent carbon unit between both sp2-hybridized carbons of alkenes. For the…
A process for in-situ oxidation of hydrocarbons in low-quality oilfields, and subsequent gas separation, offers a path to generating hydrogen for fuel and chemicals that avoids any greenhouse gas emissions. Known as Hygienic Earth Energy (HEE), the process has been…
Electrochemical reduction of carbon dioxide to hydrocarbons and oxygenates on copper involves reduction to a carbon monoxide adsorbate followed by transformation to hydrocarbons and oxygenates. To ensure the sustainability of the process, the electrochemical CO2 reduction is typically conducted in…
