Li2CO3 from brine Purities of greater than 99.9% for battery-quality lithium carbonate have been achieved using a proprietary artificial-intelligence-powered crystallization technology developed by Standard Lithium Ltd. (Vancouver, B.C.; www.standardlithium.com). The total cation contaminant levels were reduced from nearly 2,500 parts…
Conversion of plastic packaging to BTX and olefins is demonstrated
Anellotech (Pearl River, N.Y.; www.anellotech.com) recently announced a successful laboratory demonstration of a process to convert mixed plastic waste into a host of useful starting materials for new plastics. The process (diagram), known as Plas-T-Cat, would take place in a…
Progress towards lithium-sulfur batteries
An international team, led by Mahdokht Shaibani from Monash University (Melbourne, Australia; www.monash.edu), has developed an ultra-high capacity lithium-sulfur battery with better performance and lower environmental impact than current Li-ion batteries. The team includes people from Monash University, University of…
Batteryless machine-health monitor enabled by low-power computer chips
Everactive (Charlottesville, Va.; www.everactive.com) has just launched its Machine Health Monitor (MHM) product for batteryless vibration and temperature sensing of process machinery (photo). The MHM harvests waste energy from small temperature differentials (10°F or greater) and ambient light (100 lux…
Oxidative precipitation recovers nickel and cobalt from ore
An alternative method for processing mixed nickel-cobalt hydroxide precipitate to separate the nickel from cobalt and manganese has been proposed by a team from the Bandung Institute of Technology (Bandung, Indonesia; www.itb.ac.id), the Indonesian Institute of Sciences (Bandung) and the…
Chementator Briefs
Caprolactam Genomatica (San Diego, Calif.; www.genomatica.com) recently announced the production of the world’s first renewably sourced ton of caprolactam, the key ingredient for nylon-6. The company made the caprolactam by fermenting plant sugars with engineered microbes, departing from the conventional…
Bio-inspired textiles recover oil from water
A technology that removes oil from the surface of water without pumps or chemicals has been developed by German researchers at the Universities of Bonn (www.uni-bonn.de) and Aachen (www.uni-aachen.de) and textile-manufacturer Heimbach GmbH (Düren, Germany; www.heimbach.com). Textiles with special surface…
Converting solid waste to ketones
Researchers at Lawrence Berkeley National Laboratory (Berkeley, Calif.; www.lbl.gov) recently reported a process for converting various blends of cellulosic biomass and municipal solid waste (MSW) into aliphatic methyl ketones. The team used bio-derived ionic liquids to first break down the…
Simultaneously treat many mixed-waste streams
A team of researchers at Worcester Polytechnic Institute (WPI; Worcester, Mass.; www.wpi.edu) are investigating hydrothermal liquefaction (HTL) to simultaneously treat a variety of municipal waste streams and create biofuels. “HTL is an emerging technology for the conversion of various types…
Validating hydrogen embrittlement models for steel tanks
Hydrogen is transported in steel tanks and pipelines. However, H2 causes embrittlement of steels by accumulating at microstructures called dislocations and at the boundaries between the individual crystals of which the steel is composed. The accumulation of hydrogen weakens the…
