§ Mr. SheermanTo ask the Secretary of State for the Environment how many tons of(a) mining and 533W (b) quarrying waste is produced in the United Kingdom every year. [21734]
§ Mr. ClappisonThe best available estimates of production of waste materials from mineral extraction in the United Kingdom between 1985 and 1994 are summarised below. Wastes produced by deep mining of coal have fallen steadily since 1985 and in 1994 amounted to only 40 per cent. of the weight produced in 1985. Wastes from other mining and quarrying activity rose by 38 per cent. between 1985 and 1988 and then fell back to 1985 levels by 1992. Since 1992 they have risen again.
