HC Deb 04 July 1983 vol 45 c32W
Mr. Skeet

asked the Secretary of State for the Environment what methods of disposal of calcium sulphate slurry from scrubbers or fluidised bed combustion operations has been assessed.

Mr. Waldegrave

No detailed assessment has yet been made, but the CEGB is looking into the question. The wet process produces a difficult acidic slurry, but other processes exist which could produce a usuable waste. No information is yet available on the disposal of wastes from fluidised bed plant.
