Recycling sorting staff manually remove items that should not be included in recycling carts (contamination) from the recycling sorting line. In order to ensure recycling sorting staff don’t have to handle these materials directly, please only include acceptable items in your recycling cart.
To dispose of medical materials and the items listed above, please place medical materials in secured bags and include in garbage waste.
Also, please maintain a minimum social distance of two metres when interacting with waste collectors and wait for the truck to depart before removing your bins from the curb.
