Historically, the UK has been very dependent on [[Landfill]] or [[Incineration without Energy Recovery]] for [[Disposal]] of [[Residual Waste]]. The landfill diversion targets set in the mid 1990s promoted [[EfW]] developments. The diversion of residual waste away from [[Landfill]] and into [[EfW]] processes was intended to reduce emissions of methane and pollution originating from [[Landfill]] sites and increase production of renewable energy<ref name="foo" />. [[Energy from Waste]] is the now the main method for dealing with [[Residual Waste]], with [[Landfill]] of [[Residual Waste]] being the least preferred method, as outlined in the [[Waste Hierarchy]]<ref name="foo" />. | Historically, the UK has been very dependent on [[Landfill]] or [[Incineration without Energy Recovery]] for [[Disposal]] of [[Residual Waste]].

In | In 2021, the amount of residual waste that was sent to [[EfW]] processes in the UK increased by 5.5%, amounting to a total of 14,850 kt being sent to 53 operational EfW facilities across the UK<ref name="foo2> [https://www.tolvik.com/published-reports/view/uk-energy-from-waste-statistics-2021/ Derived from Tolvik EFW Statistics 2021, Published May 2022]</ref>. This was against a headline/plated capacity of 16,370 kt of operational capacity and a further 5,310 kt of late stage commissioning and in construction 'plated' capacity at that time. This represented 56% of the total [[Residual Waste]] produced in the UK in 2021 (increasing from 52% in 2020)<ref name="foo2" />. The total net power exported from [[EfW]] facilities in 2019 was 8,643 GWh, this supplied 2.9% of the total UK power generation, and gives an average of 591 kWh of power generated per tonne of residual waste treated at UK [[EfW]] facilities<ref name="foo2" />. | ||
