Zero-CO2 ethane cracker technology is available commercially

A next-generation ethane-feed steam cracker designed by Lummus Technology (Houston; www.lummus.com) has the ability to achieve zero carbon dioxide emissions in the production of ethylene. The zero-CO2 design utilizes Lummus SRT pyrolysis furnaces and a state-of-the-art product-recovery system. Lummus improved…

Biodegradable corn-based adhesive is non-toxic, with tunable properties

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…

Chementator Briefs

Biomethane Last month, NextChem, a subsidiary of Maire Tecnimont S.p.A. (Rome, Italy; www.mairetecnimont.com) was awarded a contract by ENGIE subsidiary Storengy (Bois-Colombes Cedex, France; www.storengy.com) to perform an advanced basic-engineering study for a plant that will produce second-generation biomethane from…

A more-sensitive way to differentiate chiral compounds

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…

Commercial debut for sand-based thermal-energy storage

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…

Upcycling of waste ABS into 3D-printable material with enhanced properties

In an advancement toward circularity for commodity plastics, researchers at the Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) have developed a method for upcycling the commodity thermoplastic acrylonitrile butadiene styrene (ABS) into an ABS-vitrimer material that can be…

Extending the operating temperature of biological phosphorus removal

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…

Limpet tooth inspires strongest biomaterial

An interdisciplinary team of biologists, chemists and engineers from the University of Portsmouth (U.K.; www.port.ac.uk) have become the first to successfully grow a limpet-inspired biomaterial with extreme strength. The common limpet (Patella vulgata) is a small, snail-like mollusk with a…

Biosynthesis of renewable, high-energy-density, cyclopropane-based fuels

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…

Hybrid membrane separates CO2 with both high permeability and selectivity

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…
