Recycling crews cannot empty a contaminated bin. If this goes into the recycling wagon then the entire wagon-load becomes contaminated and it may have to be diverted to landfill rather than its proper recycling channels.
If your recycling bin (grey or brown) has been contaminated the crews will sticker your bin as contaminated and leave you with some recycling sacks to tide you over until next collection day.
You can either remove the contaminated waste yourself and it will be collected as normal on the next collection day or you can request a fresh start where a refuse vehicle will empty your bin and leave you with an empty bin ready to recycle correctly.
The cost of this service will be £7.50 per bin.
