Energy from Waste (EfW)




Energy from Waste (EfW)


The recovery of energy from waste has a major part to play within the waste hierarchy. Once the preferred options of reducing, re-using and recycle waste resources have been exhausted, Energy from Waste (EfW) is one of the best available techniques for recovering residual energy from the waste that remains.

As one of the UK’s leading suppliers of integrated waste management and environmental services, Grundon was quick to recognise the significance of Energy from Waste technologies. Energy from Waste facilities divert huge volumes of waste from landfill and provide a sustainable option for energy recovery. They can generate substantial amounts of energy, helping to reduce the dependence on unsustainable fossil fuels. In doing so, Energy form Waste facilities make a vital contribution to both the sustainable energy generation capacity and the energy security of the UK.



Our Lakeside Energy from Waste facility at Colnbrook, a joint venture with Viridor, has been fully operational since January 2010. The facility, close to Slough and Heathrow Airport, is capable of recovering energy from over 410,000 tonnes of residual (non-recyclable) waste per year from local authorities and businesses, and diverting 100% of waste from landfill. The Lakeside Energy from Waste facility generates 37 MW of electricity, a small amount of which is used to power the plant itself, with the vast majority being exported to the National Grid. Lakeside produces enough electricity to power approximately 50,000 homes, which is equivalent to a town the size of Slough.

The Lakeside Energy from Waste facility has been designed with the potential to export surplus heat, making it a combined heat and power (CHP) plant.

Lakeside Energy from Waste remains one of the most modern facilities of its type in the UK, operating under strict environmental controls under a permit administered by the Environment Agency.

What are the benefits of using an Energy from Waste technology and facilities such as Lakeside EfW?


Energy from Waste complements Grundon’s existing Materials Recovery Facilities for recovery and recycling. It offers the Best Practical Environmental Option (BPEO) for the minimisation and treatment of residual (non-recyclable) waste.

Our Lakeside Energy from Waste facility is strategically located close to major sources of waste, with a catchment area that includes Berkshire, parts of Buckinghamshire, London and Surrey. There are many good reasons that you should consider using Lakeside Energy from Waste for the disposal of your residual waste:

The process is compatible with and is complementary to our high levels of recycling:

It is a cost effective option which minimises your exposure to continually increasing Landfill Tax
It offers a sustainable solution for both waste management and energy generation
It meets Waste Framework Directive requirements by diverting 100% of your waste from landfill
It reduces the amount of harmful greenhouse gases, such as methane, generated via landfill sites
The Energy from Waste process displaces carbon dioxide produced by the burning of conventional fossil fuels
It reduces the reliance on non-renewable energy sources
It reduces the strategic dependence on imported energy
It helps customers, such as local authorities, to meet their landfill diversion targets and avoid significant fines arising from non-compliance

How does the process of Energy from Waste work?


Residual waste, which is the waste left when the recyclable materials have been removed and recovered, is fed into the twin furnaces at Lakeside. The heat that is generated through the incineration process is used to power a steam turbine which generates electricity.

Any ferrous and non-ferrous metals (typically 3-5% by volume) are extracted from the inert bottom ash which results from the combustion process.

The Incinerator Bottom Ash (IBA) can be recovered and recycled for used as a substitute for natural aggregate. Recycling IBA replaces the need to use non-renewable materials as aggregates and reduces the environmental impact of their extraction. This means that Lakeside Energy from Waste operates with zero waste to landfill.
Air Pollution Control residues (APCr) – the residual ash remaining after stringent filtering and scrubbing is usually disposed of at hazardous waste landfill. Grundon has invested in innovative and pioneering technology that uses these residues in the production of carbon-negative building blocks.

The Energy from Waste plant emissions are regulated through the Integrated Pollution Prevention and Control regime and are currently monitored by the Environment Agency. Emissions from the stack comply with the most stringent UK and European pollution control standards.

Lakeside Energy from Waste processes over 410,000 tonees of residual waste every year, generating 37 MW of renewable electicity for distribution to the National Grid – enough to power approximately 50,000 homes.
