  CO2-to-syngas . . . Scientists from the University of Illinois at Chicago ( www.uic.edu) have developed a catalytic system — molybdenum disulfide and an ionic liquid — to convert CO2 into synthesis gas, (syngas; a mixture of CO and H2 that is used for making liquid fuels and chemicals, such as methanol). Unlike alternative CO2-reduction processes, which only generate CO, the new catalyst...

Water and wastewater treatment are extremely important at liquefied natural gas (LNG) facilities and other industries that are blossoming due to the shale-gas boom. Engineering concerns are similar to those of other industrial water-treatment and power-generation systems, but with the added issue of adequate treatment for entrained hydrocarbons. With proper system design and operation, plant personnel can...

What is said to be the world’s first fermentation pathway from methane to lactic acid has been demonstrated by Calysta, Inc. (Menlo Park, Calif.; www.calysta.com). The fermentation process begins with an organism that feeds off of methane rather than typical sugar-based feedstocks and, through synthetic biology, has been altered to convert that methane to high levels of lactic acid. This lactic acid...
