An Australian research team has solved one of the worlds big industrial waste headaches - what to do with spent pot lining (SPL) from aluminium smelters.
In a major advance for sustainable mineral production, the "Alcoa Portland SPL Process" developed jointly by Portland Aluminium, Alcoa, Ausmelt and CSIRO renders the hazardous waste harmless and at the same time produces two commercial by-products.
Aluminium smelters worldwide produce about half a million tones a year of the toxic byproduct which, in many cases, simply has to be stored on site because local regulations prevent its disposal in landfill.
Now the Australian breakthrough has turned what was an intractable problem into economically useful products.

Waveguides are widely used for filtering, confining, guiding, coupling or splitting beams of visible light. However, creating waveguides that could do the same for X-rays has posed tremendous challenges in fabrication, so they are still only in an early stage of development.
In the latest issue of Acta Crystallographica Section A: Foundations and Advances , Sarah Hoffmann-Urlaub and Tim Salditt report the fabrication and testing of...
