Nowadays, energy recovery goes hand-by-hand with waste elimination. There are different ways of getting energy from waste: incineration, gasification, methanisation,…. Traditionally, the most used one has been incineration, although the other treatments are emerging technologies that are being quickly extended.
Incineration allows obtaining energy at the same time that the volume of waste is reduced, as well as the use of landfill. The high combustion temperature makes it possible to recover energy from the waste and use it for heating, industrial applications and electricity production.
Three different kind of waste are accepted in an incineration facility:
| > |
Household waste |
| > |
Non-hazardous industrial waste |
| > |
Rejects from sorting centres |
|
|
Waste collection vehicles dump the waste in vast trenches where it is mixed and transferred to an oven. The waste is then burnt at temperatures reaching 1000°C, producing steam that turns turbines, which in their turn produce electricity. The fumes produced in the combustion are treated by a dry or wet method. Ashes can be reused in civil engineering. |
