In order to handle the growing volume of waste textile materials, recycling processes must begin significantly scaling up. Lenzing AG (Lenzing, Austria; www.lenzing.com) and Södra (Växjö, Sweden; www.sodra.com) are joining forces to scale up the OnceMore textile-recycling process, which is…
A cyclic activated-sludge (AS) process, trademarked te-cyc, combines biological treatment and solids settlement in a single treatment step, thereby significantly reducing the footprint compared to a conventional AS plant, which requires three separate processes — primary settlement tanks, aeration tanks…
Lufthansa Technik AG (Hamburg; www.lufthansa-technik.com) and BASF SE (Ludwigshafen, Germany; www.basf.com) have developed a surface film, tradenamed AeroSHARK, that mimics the fine structure of a shark’s skin for reducing friction. The technology is to be rolled out on Lufthansa Cargo…
Construction has begun on a market demonstration facility for manufacturing chloromethyl furfural (CMF) and hydrothermal carbon (HTC) from a variety of waste biomass feedstocks. With subsequent chemical transformation, these flexible intermediates can be converted into final products, such as polyethylene…
Biomass Corn stover is among the major feedstocks for biorefineries, and can be converted to bioethanol. When corn stover contains moisture above certain levels, it can clog conveyers and chutes during processing, leading to operational problems and process stoppages. To…
A newly launched modular waste-to-energy system is capable of delivering off-grid heat and power with competitive economics to a variety of locations, including military bases, remote sites and commercial installations, according to creator Enexor BioEnergy LLC (Franklin, Tenn.; www.enexor.com). Under…
Industrial heat pumps (diagram) are a relatively mature technology that converts low-temperature waste heat into a more usable heat at a higher temperature (above the “pinch point”). However, the technology has been limited to applications of up to 100°C. Now,…
Researchers from the Biological Systems Unit at the Okinawa Institute of Science and Technology Graduate University (OIST; Japan; www.oist.jp) have developed a bioelectrochemical system that uses bacterial communities to break down organic material from raw wastewater, and removes both nitrates…
Redox flow batteries (RFBs) are a promising alternative to lithium-ion batteries for storing large quantities of renewable energy (see Chem. Eng., September 2016, pp. 14–20), but they have always been too expensive for the mass market. Now, researchers at the…
The purification of seawater and wastewater for agriculture and human consumption is becoming increasingly important in water-scarce regions. Along with the removal of salt, rendering ocean water and wastewater suitable for humans and plants also involves removal of elements that…
