==Residual Waste EfW==

Energy from Waste plants that use [[Waste Derived Fuel]] (WDF) but do not exclusively accept biomass will still have a portion of biomass in their feedstock. Often this is quantified as the amount of the C-14 isotope in the fuel compared to total carbon in the feedstock. This is an important parameter as the heat/electricity produced from an EfW plant that can be classified as renewable (and therefore eligible for subsidies e.g. [[ROC]], [[RHI]]) is derived from the biogenic portion of the feedstock. Moreover, the amount of biogenic content relates to landfill cost saved by diverting this waste away from landfill<ref>WRAP, 2019.

This quantity of biomass in the feedstock also forms the basis of the [[Renewable Qualifying Multiplier]] ([[RQM]]) to calculate the quantity of payments made to a generator in line with the [[Contract for Difference]] ([[CfD]]) scheme.<ref>LCCC, 2019.

The non-biomass portion of waste feedstock (e.g. plastics) produce a similar product gas to biomass-derived gas. Additionally, they both have similar fuel characteristics, like high volatile matter content and low fixed carbon content. Subsequently, this enables similar processing conditions and gas cleaning techniques to be used in waste and biomass [[EfW]] facilities. However, significant differences do still exist between these two feedstocks, for example, generally higher ash content and higher content of other contaminants in a mixed waste feedstock and these warrant specific changes in the [[EfW]] process.<ref>Waldheim, 2018.
