Twelve ‘hi vis’ residents had a very interesting visit to FCC ‘Energy from Waste’ site near Aylesbury where BCC send all our ‘grey bin’ waste to generate electricity rather than landfill. Currently about 300 tonnes of waste/annum generates 26MW/hour is electricity, enough for 40,000 homes.
Waste is delivered by lorries where large grabs drop it into a moving grate where it is incinerated into heat, flue gases and ash.
The heat drives a steam turbine and generated electricity added to the ‘national grid’.
Flue gases are cleaned to within safe limits and essentially only water vapour and carbon dioxide released. Extractable metals are separated from remaining ash.
