Aggregates and the environment
Actions taken by the aggregate industry to reduce the environmental impact of aggregate production include the increased use of recycled concrete as aggregate and artificial aggregates made from by-products of other industries. All active UK quarries are required to have restoration plans. These include the use of worked-out quarries as landfill sites before landscaping and the use of gravel pits for recreational water sports, nature reserves, etc.
Where feasible rail or water transport is used in preference to road transport.
