Greener chemistries and equipment advances provide more sustainable water-treatment options for chemical processors Chemical processors face tough challenges when it comes to the water used in the facility — namely, water scarcity and ever-increasing regulatory requirements associated with discharging effluent.…
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…
Last month, Evonik Industries AG (Essen, Germany; www.evonik.com) and Siemens AG (Munich, both Germany; www.siemens.com) launched a second phase of their joint research project, Rheticus II, which aims to develop a test plant that will use CO2 and water, as…
Carbon fibers are typically fabricated by the oxidation of a polymeric fiber, such as polyacrylonitrile (PAN) at 200–300°C, which generates a large amount of exhaust air containing several hundred parts per million (ppm) of hydrogen cyanide and ammonia. This is…
A new carbon-utilization technology developed by SeeO2 Energy Inc. (Calgary, Alta., Canada; www.seeo2energy.com) takes advantage of thermodynamics in a high-temperature electrolyzer to efficiently convert carbon dioxide into CO and O2 with 100% selectivity. Based on the principle of a reversible…
Phenolic compounds, such as chloro- and nitrophenols, are potentially hazardous when found in soils and the workplace. Normally, such compounds are detected with techniques such as mass spectrometry. There are several mechanisms for degrading and detoxifying contaminants: bacteria use specialized…
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…
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…
Removal of phosphorus and other nutrients from wastewater is critical to preventing harmful algal blooms in coastal waters. Enhanced biological phosphorus removal (EBPR) — which relies on microbial communities that consume phosphate, reducing its concentration in the wastewater — has…
