By Cordelia Hsu and Helen Clark NEWCASTLE/PERTH, June 18 (Reuters) – Australia’s first carbon refinery opened in New South Wales, capturing carbon dioxide from explosives giant Orica’s ammonia-making operations on Kooragang Island and turning it into products such as concrete, paper and glass. MCI Carbon has been developing the Myrtle Carbon Capture Utilisation and Storage technology for 15 years and the demonstration plant can potentially capture 2,500 metric tons of CO2 a year.
