Carbon Cycle’s gypsum purification process cleans up radioactive fertiliser waste
The patented process could prevent environmental damage and provide a new source of gypsum and rare-earth metals
A company called Carbon Cycle has developed a process that takes waste gypsum or chalk and purifies it so that it can be used as high-grade white filler in plasterboard and cement. This process could be used to clear up the unsightly, not to mention radioative, phosphogypsum stacks that result when the fertiliser industry produces of phosphoric acid.
