RECOVER

Energy recovery – The waste is burnt at Allerton Waste Recovery Park to produce electricity.

Key Facts:

320 000 tonnes of Waste processed every year.

All general waste and waste that is non-recyclable waste from Household Waste Recycling Centre come to Allerton Waste Recovery Park

Up to 70 tonnes per hour is processed in the:

Mechanical Treatment Hall

Features various sorting technologies including:

• Trommels – 40cm and second set 30cm, 17cm and 7cm
• Shredders – open the bin bags.
• Ballistic separators – sort 2D waste from 3D waste
• X-ray sorting units - picks out glass and rubble.
• Magnets and eddy current separators for metals – for ferrous metals and aluminum.
• Near infra-red separators for plastic types
• Hand sorting cabin
• Recyclate bales – square bales that are exported for recycling.

Anaerobic Digester (AD)

• 40,000 tonnes a year - or 114 tonnes daily – of organic waste is transferred to the AD.
• Fermented under carefully controlled conditions for 20 to 25 days.
• Generates renewable biogas which is exported to the National Grid up to 1mw.
• Produces digestate – this is transferred and used as a fuel in the EfW.

Energy From Waste (EfW)

• The Energy from Waste plant treats waste from the Mechanical Treatment Hall and digestate from Anaerobic Digestor
• Waste is burned at a minimum of 850°C
• Left over ash is recycled and used as construction aggregate.

Air Pollution Control Residue (APCR)

• Strict emissions limits in place – standard throughout Europe
• Limits are deemed safe by the World Health Organisation
• Pollution control system consists of:

• Selective non-catalytic reaction - reduces nitrogen oxides to into nitrogen.
• Dry lime to neutralise acid gases.
• Activated carbon to neutralise dioxins, furans, and mercury.
• Filter system to capture particulates.
