Waste to energy
There are several plants at the site in Doel which mainly process non-hazardous waste products. Their size and capacity make this a site of global proportions. There are
- 3 grate incinerators;
- 3 fluidized bed incinerators;
- a pre-treatment plant for energy-rich waste;
- a processing centre for lamps and other mercurial waste;
- an ash treatment plant;
- a dispatch warehouse;
- a category 2 landfill;
- a category 1 landfill;
Doel site: steam and power for 170,000 families
The largest and most important plants are Indaver’s three grate incinerators and SLECO’s three fluidized bed incinerators. Together they process more than one million tonnes of waste per annum. This waste consists of household waste, similar industrial waste and sludge. Formerly the steam released during incineration was converted into electricity via three turbines and fed into the electricity grid, enough to meet the electricity needs of 170,000 households. Only part of the steam was supplied directly to a neighbouring company Ineos Phenol. Today, the steam is fed primarily into the ECLUSE-steamnetwork to meet the demand of steam of 5 industrial companies in Waasland Port. The remainder is converted into electricity.
Approximately half of the waste that is processed in these plants is bio-organic. Therefore half of the recovered energy is considered renewable.
