These bins are designed to store rubbish that can be recycled. Each bin is colour coded so you know which type of rubbish should go in each bin. Glass, plastic and paper are the main types of rubbish that can be recycled. The lid of the bin is designed with 2 flaps, one small and one large. The small flap, when lifted will cause the large flap to dip inside the bin. The large one when lifted will not affect the small one.
