CONTRACTORS in Europe are using more power station waste products in construction projects than ever before, the latest industry figures show.
More than 30 million tonnes of waste ash, slag and flue gas by-products were used by the industry in 2002. This accounted for over 52 per cent of the total power station waste, said the European Coal Combustion Products Association.
Power stations produced 63.3 million tonnes of waste material in 2002, up 5 per cent on the previous year, thanks to an increased used of coal in power production.
Most of the material was used as concrete admixtures in the form of pulverised fly ash, bottom ash and boiler slag.But the installation of new desulphurisation plants at power stations saw the amount of flue gas gypsum used in construction leap to 10.5 million tonnes.
