Abstract: 
In the Netherlands, the use of secondary raw materials is strongly promoted by the authorities and by industry. This is for the most part a direct result of the rising cost of waste disposal and the limitations on the extraction of primary raw materials from Dutch soil. The demand for raw materials for construction purpose in the Netherlands is estimated at 150 Mtonnes/year.

More than 90% of secondary raw materials are currently used in road construction. Use in concrete is only marginal because of higher cost compared to primary raw materials. Exceptions are blast furnace slag used for blast furnace cement (a more than 50% share in the Dutch market) and E-fly ash. The application of crushed concrete mixed with masonry for the manufacture of sandlimestone bricks, and aerated concrete is being investigated but seems problematic because current specifications concerning strength, colour, and leaching can not always be met.

Building, renovation and demolition operations in the Netherlands currently produce approximately 14 million tonnes of construction and demolition wastes (CDW). After dredged materials (65Mt) and surplus manure (14.5 Mt) this is therefore the largest waste stream in the Netherlands. For comparison, the total household waste production in the Netherlands is 5.5 million tonnes per annum. Figure 21 describes the source and waste volumes in the three sectors of the building industry.
