§ 78. Mr. ShersbyTo ask the Secretary of State for the Environment what is his policy for containing the emission of chlorofluorocarbons arising from dry cleaning establishments; what consultation has taken place with the dry cleaning business on this matter; and if he will make a statement.
§ Mrs. Virginia BottomleyOfficials of the Department of the Environment and of the Department of Trade and Industry hold regular meetings with representatives of the users of chlorofluorocarbons (CFCs). including the dry-cleaning sector, on the steps that they are taking to reduce use of CFCs to the maximum possible extent. The major dry cleaning solvent used in the United Kingdom is perchlorethylene rather than CFC113.
I am advised that all dry cleaning machines are sealed to be gas-tight, that solvent purification takes place within machines and that they are fitted with refrigeration units to condense solvent vapours and minimise potential emissions. Any solvent remaining in residues is recovered before exposure to the atmosphere. The industry is nevertheless looking at ways of developing even greater economy of use and has produced guidelines on machine operation, which includes proper use of solvents.
