Where the uncertainty lives
The largest σ contribution in this category is general waste (residual, to landfill) (99.0% of the category's variance). Waste is weighed at the venue weighbridge, so the σ sits in the disposal-route factors. DEFRA's waste factors cover collection and treatment only, so recycled and digested streams come out close to zero and landfill carries almost all of the category. Reduction levers that move this line will tighten the band the most.
