Using Waste Heat To convert large amounts of waste heat into electricity as efficiently as possible, turbines with a high degree of efficiency are required that work with a special conversion process — the organic Rankine cycle (ORC). In a…
A hydrogen-fired furnace for ceramics
This month, a demonstration experiment will begin on a new firing furnace for ceramics that is being developed by NGK Insulators, Ltd. (NGK; www.ngk.co.jp). The furnace is fired with hydrogen instead of fossil fuels, thereby reducing CO2 emissions. H2-fired combustion…
These nonwovens are electrically conductive, but thermally insulating
Researchers at the University of Bayreuth (Germany; www.uni-bayreuth.de) have developed nonwoven materials that exhibit an unusual combination of high electrical conductivity and extremely low thermal conductivity. These composites of carbon and silicon-based ceramic can be manufactured and processed cost-effectively by…
Scaleup for a hydro-organic-metallurgical process
Following a successful proof-of-concept to recycle spent lithium-ion batteries (LIBs) using reagent extracted from fruit peel waste, Nanyang Technological University, Singapore (NTU; www.ntu.edu.sg) has partnered with Se-cure Waste Management Pte. Ltd. (SWM; Singapore; www.se-curewaste.com) to scale up the technology in…
Converting algae shells into ‘tunable’ perovskites
A research team, led by scientists at the Center for Molecular Bioengineering (B CUBE) at the Technical University of Dresden (Germany; www.tu-dresden.de), has converted mineral shells of single-celled algae into lead-halide perovskites with tunable physical properties. The new perovskites have…

PS Recycling INEOS Styrolution America LLC (Aurora, Ill.; www.ineos-styrolution.com) and Agilyx ASA (Oslo, Norway; www.agilyx.com) are advancing the development of a previously announced 100-ton/d TruStyrenyx chemical-recycling facility in Channahon, Illinois. TruStyrenyx is a partnership between Agilyx and Technip Energies N.V.…
Bio-inspired synthesis leads to new hydrogen-reaction mechanism
In synthesizing a new molecule that mimics the nickel-iron (NiFe) hydrogenase enzyme, a team of researchers from University of Illinois Urbana-Champaign (www.illinois.edu) may have uncovered a promising alternative to the platinum-based catalysts typically used in the electrolysis of water to…
Optimizing CIP for membrane filtration plants
Membrane filtration plants are often used in the food and dairy industry to separate or concentrate substances without thermal stress. Until now, cleaning-in-place (CIP) operations for this equipment was energy- and water-intensive, requiring three or four individual cleaning steps with…
Technology launched for enhancing propane recovery in GSP
The gas subcooled process (GSP) is a method for low-temperature separation of natural-gas liquids (ethane, propane) from natural gas. Depending on the current market prices of ethane and propane, gas processors extract ethane from the natural gas or reject it…
New compressor design for H2 is leak-proof and improves efficiency
A newly developed hydrogen compressor has a linear motor design and is hermetically sealed to increase the efficiency of H2 compression while avoiding potential problems associated with H2, such as leaks and embrittlement. The linear motor-driven reciprocating compressor (LMRC), developed…
