How it works

Food waste comes to our Deerdykes recycling facility from all around Scotland’s Central Belt.

This waste is transported to our site and screened to find out it’s contents. This is important so that we know how much we can accept, how the chemicals will affect the digestion process and if there is anything in the waste that might harm the recycling technology.

Once screened, the waste is fed into the pasteurisation process and then sent to our anaerobic digester where biological treatment begins. During this stage, micro-organisms and heat break down the wasted food in sealed, oxygen-depleted tanks to produce an energy-rich biogas.

This biogas is then converted into low carbon heat and electricity as well as a natural fertiliser for use in agricultural land spreading.
