How many can you name?
The blue-lidded bin. We all have access to one - but how many of us can name the eleven different types of rubbish that can be recycled in it?
Paper - yes, that's obvious. Plastic bottles - those too.
But what about aerosols? And what definitely doesn't go in?
Dale Garwood from Veolia Watford has the answers, and he's made a series of short films to address your recycling queries.
