The annual usage rate of a technology may either be equal to
the annual capacity of said technology or a fraction of the annual
capacity if a facility operates below its design capacity as a consequence
of the waste scenario. Determining the annual usage rate
depends on the specific technology in use (see details provided
in the Supplementary materials); for example, the thermal capacity
of an incinerator limits the amount of waste to be treated. Thus,
the annual usage rate of an incinerator (AURWtE) [tonne/year] in a
specific waste scenario is inversely proportional to the calorific
value of the waste, i.e. with increasing Lower Heating Values
(LHV) [MJ/tonne], less waste can be incinerated. The Annual Mass
Capacity (AMC) [tonne/year] of a plant was multiplied by the ratio
Design Heating Value (DHV) [MJ/tonne] over the Lower Heating
Value of the waste (LHVw) [MJ/tonne], in order to adjust the annual
tonnage, as shown in Eq. (6).
