The R1 status of an Energy from Waste (EFW) facility determines whether that facility is regarded as Disposal or classifies it as an Energy Recovery Facility. The EU standard sets a requirement to meet high levels of power conversion efficiency to classify it as an R1 (and may need to be a CHP facility to fully meet the guidance).

To qualify as R1 status the EFW facility must :

Only R1 facilities can receive WDF from other EU countries for processing – export to other EU countries for Disposal (for example to an Incinerator that does not have R1 status) is illegal[2].

The formula for calculating the R1 status is given below:

P1 ef = (Oexp - (Ef + Eimp))/(Ef + Eimp + Ecirc)

all figures as equivalents in accordance to BREF,Chapter 3.5.6

  • Ef = annual energy input to the system by fuels with steam production (GJ/y)
  • Eimp = annual imported energy (Note: energy from the treated waste (Ew) is not included)
  • Ecirc = annual energy circulated
  • Oexp = annual exported energy (combined total of heat plus electricity as equivalents)

"If the result is higher than 1: This shows that the plant minus imported energy with steam production is exporting (BREF) or producing (ECJ C-228/00) more energy than that which is required to operate the total waste incineration process."[2]
