How energy recovery works

Incineration of waste is among the most tightly regulated industrial processes in Europe, and our facility has been designed to satisfy the strict standards of the European Union’s Industrial Emissions Directive.

As well as generating electricity, by-products of the process can be recycled, such as metals and ash.

Energy-from-waste process

Waste collection vehicles discharge their waste into a bunker where the waste is mixed to ensure an even burn in the furnace. Water sprays and induction fans are used in the reception hall to reduce levels of dust and smell.

The waste is loaded by crane into a feed hopper, then travels down the feed chute into the furnace.

Inside the furnace, a series of rollers move the waste through the furnace where it is dried and burned at temperatures of around 1,000Ā°C.

Burning waste in the furnace creates hot flue gases which travel through a boiler transferring heat to water that runs through the boiler pipes.

The hot water creates steam and the steam drives a turbine which then generates electricity.

Ash created by burning the waste drops into a quench tank, then along a conveyor. Ferrous and non ferrous metals are separated within the ash treatment plant and the remainingĀ  product can be used in the construction industry.

The gases from the burned waste are thoroughly cleaned to neutralise acid gases and remove dioxins and heavy metals. The gases are then passed through a fine fabric filter to capture particles before being released through a chimney, which is continuously monitored.
