Energy from waste

After waste has been sorted via mechanical treatment and anaerobic digestion, any remaining rubbish is used as fuel in the Energy from Waste  - or EfW - part of the facility.

Energy from Waste is a process that allows the recovery of energy, created by burning waste, in the form of electricity and heat.

The energy from waste process involves burning waste at a minimum of 850C, with the combustion process creating steam which in turn powers turbines to create electricity.

Some of the electricity created is used at Allerton Waste Recovery Park but the majority is exported to the National Grid by underground cables.

Enough electricity will be created to power at least 40,000 homes each year (based on Office of National Statistics data).

In addition to incineration, the energy from waste facility includes comprehensive filter systems to capture and control emissions.

The bottom ash created by the process is used for construction aggregate and is likely to be used in road building. Around 70,000 tonnes of aggregate are produced each year.
