Which bin for plate scrapings and leftovers?
Usual answer in the UK
Food waste Food waste caddy
All cooked food leftovers, including rice, pasta and dairy, go in the food waste caddy.
Does every council do this?
Most councils follow the answer above, but bins and sorting rules are set locally, and a few councils still do things differently. If your bin has a sticker, or your council sent a leaflet, follow that. Enter your postcode to go straight to your council's guidance.
