US: Elixsys has completed a 100hr continuous pilot test to extract ammonium sulphate and calcium carbonate from flue gas desulphurisation solids at a coal-fired power plant in Pennsylvania. Products made using the company’s proprietary process meet the specifications for fertiliser-quality ammonium sulphate and technical-grade calcium carbonate.

The company intends to start a commercial-scale project of its technology in 2019 once it finds a utility partner. Full-scale operations are planned by 2022. The company is also starting pilot testing on another process to extract metals from coal ash.
