HC Deb 19 December 1972 vol 848 cc337-8W
Mr. Skeet

asked the Secretary of State for the Environment what information he has about a commercial process for removing fluorine from stack gases; and if he will make a statement on the state of research to date.

Mr. Eldon Griffiths

The Alkali and Clean Air Inspectorate, together with the management of the Fletton Brickworks, is seeking to develop a practicable method of removing fluorides from the stack emissions of this industry. The problem is a difficult one and at present I cannot predict a date for its solution, but I can assure my hon. Friend that it is being tackled energetically.
