Waste materials – power stations
The energy power stations of Nuon produce waste materials. These are re-used, incinerated or deposited in landfill facilities.
The burning or gasification of coal at installations (Hemweg 8 and Willem-Alexander power stations) leaves residual materials. These can still be put to good use as a raw material for other products. The sulphur released from coal during the incineration process at the Hemweg power station is captured and then transformed via a chemical process into plaster for application as a building material. At the Willem-Alexander power station the sulphur compounds are converted into elementary sulphur. This is used in the chemical industry as a raw material. Fly ash and bottom ash are applied in e.g. the cement industry and road-building sector.
