Abstract

Dutch unconsolidated Quaternary and Tertiary deposits constitute major resources of sand, gravel and clay, exploited mainly for construction works and the building-materials industry. Limited surficial occurrences of Cretaceous chalk and Triassic limestone and dolomite are carbonate resources, used mainly for the production of cement. From 1999 to 2003, an average amount of 90 Mt of sand, 4.9 Mt of gravel, 3.9 Mt of clay and 1.6 Mt of carbonate rock was extracted annually. Between 10 and 14 Mt/a of the aggregates production was exported; imports of aggregates rose from 30 to 45 Mt/a. For reasons of sustainability, policy has been developed to stimulate the application of secondary building and construction materials, i.e. recyclable waste materials and industrial by-products, as alternatives for natural materials. Their total use rose from 7 Mt/a in the early 1980s to ~32 Mt/a in the early 2000s.
