§ Mr. WigleyTo ask the Secretary of State for Energy what action has been undertaken by his Department to promote the use of colliery spoil, slate waste, power station ash and slag as substitute materials.
§ Mr. YeoI have been asked to reply.
The Government are fully committed to the use of these materials as alternatives to primary aggregates. A report commissioned by the Department of the Environment into the "Occurrence and Utilisation of Mineral and Construction Wastes", was published in 1991. This showed major supplies of these wastes were available for use as construction aggregates and recommended how usage could be increased. The Government are actively examining these ideas and will make an announcement later this year.
