Currently, enhanced biological phosphorus removal (EBPR) techniques in municipal wastewater-treatment plants (WWTPs) do not work well at temperatures above 25°C, which is common in warm countries. This limitation is expected to extend to more countries with the advent of global…
Cyclopropane-functionalized hydrocarbons can be excellent fuels because of their high energy densities, but organic synthesis of such fuels is difficult. In work recently published in the journal Joule, a research team led by Jay Keasling at the Joint Bioenergy Institute…
Circular dichroism (CD) is the established method for distinguishing between enantiomers — the optical isomers of molecules that are mirror images of each other. In this approach, circularly polarized light is passed through the sample and is absorbed differently by…
The recent decision by the U.S. Supreme Court limiting the authority of the U.S. Environmental Protection Agency (EPA) to regulate emissions from power plants has many concerned about the effects the decision will have on efforts to address climate change…
Last month, operation began at Polar Night Energy Oy’s (Tampere, Finland; www.polarnightenergy.com) first commercial sand-based thermal-energy storage system. The thermal storage system, which is located at the Vatajankoski power plant, is now producing low-emission district heating to the city of…
A new class of adhesives being developed by the startup gluECO Adhesives LLC (Ashburnham, Mass.; www.glueco-adhesives.com) is based on corn proteins and has a host of environmentally friendly properties, such as biodegradability and the ability to be easily removed in…
Conventional gas-separation membranes normally exhibit a trade-off between selectivity and permeability — a practical limitation referred to as the Robeson upper bound. As a result, membranes designed to selectively remove relatively low concentrations of carbon dioxide from natural gas or…
Neste Corp. (Espoo, Finland) has agreed to acquire 100% of Walco Foods, an Irish trader of animal fats. The transaction is subject to the fulfillment of customary closing conditions and regulatory approval. “This is another important step for Neste in…
The Chemours Company (Wilmington, Del.) announced that it will be expanding its Chemours Opteon YF (HFO-1234yf) capacity to help meet customer needs as they continue transitioning to lower GWP refrigerants. The Opteon YF and YF blends refrigerants are now used…
On this edition of the Chemical Engineering Podcast, senior editor Scott Jenkins speaks with environmental policy expert Deborah Gordon, senior principal in the Climate Intelligence Program at RMI. Gordon heads the Oil and Gas Solutions Initiative at RMI, and is…
