How we calculate

We estimate weekly waste by combining trash bag count, average bag size, food waste level, and composting behavior. Recycling is shown as a simple share of total household waste flow.

  • Small bag: ~4 kg
  • Medium bag: ~7 kg
  • Large bag: ~10 kg
  • Food waste adjustment: low ×0.9, medium ×1.0, high ×1.15
  • Compost adjustment: yes ×0.85 on mixed waste
