Waste reporting works best when streams are measured at the bin, not estimated at the invoice.
Waste reporting built from contractor invoices tends to flatter everyone. Weighing at the point of collection, by stream, is slower to set up and far harder to argue with.
Tracking general, dry mixed recycling and food streams separately, with diversion from landfill reported alongside the operational figures rather than in a separate annex, keeps the conversation honest.
The operational benefit is immediate: once a site can see its own contamination rate, segregation improves without any new equipment.
