It's important that you put the correct things in each bin. That's because green, brown and black bins and sacks are disposed of differently.
On collection day, if you use wheeled bins, your recycling and general waste are picked up by separate vehicles. Each vehicle goes to different locations and they're treated differently.
If you’re on sack collections, your recycling sacks and your general waste sacks are picked up by the same vehicle. This vehicle has two separate compartments. Recycling sacks goes in one, and refuse sacks goes in the other. We empty each of these compartments in a different location and they're also treated differently.
Your food bin (brown caddy if you live in a house, or grey communal bin if you live in a purpose-built flat) is collected by a different vehicle.
