§ 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.
