UV-sterilized bioreactor could reduce costs for bioproducts
Capital intensity is among the current constraints on industrial-scale fermentation, because the hardware for steam sterilization of bioreactors is complex and expensive. After recently emerging from stealth status, the startup company Biosphere (Oakland, Calif.; www.biosphere.io) has launched a new reactor…
Plasma plays a part in cleaner ammonia production
Despite the abundance of nitrogen and hydrogen, industrial ammonia synthesis remains an energy-intensive process. Electrochemical methods have been suggested as potentially lower-energy alternatives to traditional ammonia synthesis, but these newer technologies often struggle with achieving key performance metrics. By integrating…
Facts At Your Fingertips: Mass Transfer: Absorption and Stripping
Absorption and stripping are important mass-transfer operations within the chemical process industries (CPI). This one-page reference provides some basic information on the principles and applications of stripping and absorption in industrial chemistry settings. General operation In absorption, a solute from…
Efficient cavitation-based method for challenging oil separations
Many separation processes depend on chemical or thermal principles, such as solvent extraction or distillation, but in some cases, mechanical methods can provide effective separations with lower cost and energy requirements. Eirex (Vaughan, Ont., Canada; www.eirex.ca) has developed a proprietary…
New screening method reveals microbial enzymes for breaking down PET
Breaking down polyethylene terephthalate (PET) into its constituent monomers under mild conditions is a key goal of plastics recycling. Knowledge of how many naturally occurring enzymes are capable of breaking down PET, and which would be most effective in industrial…
Expanded database tool for olivine samples
Olivine, a magnesium-iron silicate mineral, is common in the earth’s subsurface, and can sometimes contain other valuable elements, such as cobalt, manganese and nickel. Olivine has been explored as a possible sink for atmospheric carbon dioxide in carbon-capture methods that…
Recycling fiber-reinforced polymers with oxygen-free static thermolysis
A new thermolysis technology developed by Composite Recycling (Ecublens, Switzerland; www.composite-recycling.ch) breaks down fiber-reinforced polymers (FRPs) into their fundamental constituents, enabling reuse as valuable feedstock for the creation of new composite materials. “Past efforts to recycle composites have allowed waste…
