An Energy Recovery Facility (ERF) is an incineration/Energy from Waste Facility that meets the measurement of energy efficiency that qualifies it as an R1 Recovery Facility.

Context and Definition

In legal terms, a ‘waste incineration plant’ means any stationary or mobile technical unit and equipment dedicated to the thermal treatment of waste, with or without recovery of any energy generated, or whether the gases resulting from the thermal treatment are subsequently incinerated [2][3]. If the Incinerator can be shown to meet the energy efficiency measurement of R1 it can be classified as a recovery facility, if it cannot it is classified as a disposal facility[4]. This means that an incinerator that generates power, and is a net exporter of power, can be described as an Energy from Waste (EfW) facility. An incinerator that is an EfW facility that meets the R1 criteria is the only type of incinerator under the legislation that can legitimately describe itself as an Energy Recovery Facility (ERF).

The most recent recent BREF guidance[5] also sets out how incinerators can be described by:

  • waste origin (e.g. Municipal Incinerators), and in WikiWaste includes Residual Waste EFW and Biomass Waste EFW,
  • the nature of the waste (e.g. Hazardous Waste Incinerators),
  • the method/type of incineration (e.g. High Temperature Incinerators)

In WikiWaste these last two bullet points are covered in High Temperature and Clinical Waste Incineration.

However, there are a range of other terms used in the sector to describe different types of incineration and Energy from Waste, the kiln/furnace used, and the subsidy that may apply to them, and these are captured in the table below:

Definitions in Legislation   Types Temp. Range °C Category   Kiln/Furnace/Reactor
Incineration With Energy Recovery Combustion 800 - 1450 Thermal Treatment Grate
Fluidised Bed
Gasification 500 - 1600 Advanced Thermal Treatment (ATT and ACT) Rotary Kiln
Without Energy Recovery Plasma
Pyrolysis 250 - 700 Advanced Thermal Treatment (ATT and ACT) Heated Tube
Surface contact

The large majority of incinerators built and operating to date in the UK are based on 'conventional' Combustion type incineration, with some development of Gasification and Pyrolysis types over the last 10 to 15 years in the UK, with varying degrees of success. These ATT/ACT types of technology were encouraged by the subsidy available for power generation under the Renewables Obligation.

The three types of incineration'EfW can have a variety of different furnaces (also termed kilns and reactors) and associated systems to ensure the uniform treatment and residence time of the waste in the kiln/reactor. The most common kilns/furnaces are Grate based (there are at least five different type of Grate), with Fluidised Bed kilns/furnaces more commonly used in Gasification.

Current Energy Recovery Facilities

Those EfW facilities that received MSW waste in England that are considered to be an Energy Recovery Facility are listed on the R1 Recovery Facility page of WikiWaste.
