HC Deb 01 July 1991 vol 194 c26W
Mr. William Ross

To ask the Secretary of State for Northern Ireland what is his estimate of the percentage of chemical waste produced by (1) Du Pont and (2) the rest of Northern Ireland which could be rendered safe by a digestion process.

Mr. Needham

Chemical waste produced by Du Pont and other similar industries in Northern Ireland is, by its nature, not digestible by any known process. The only possible methods of disposal are in hazardous waste landfill or by high temperature incineration.
