Cilydiffer waste sorting bins feature a round base and simple and compact shapes made of sturdy and wear-resistant materials, which makes them especially suited to support waste sorting schemes in most public and private settings. Bins are made of concrete with marble grit, fitting colour inserts to facilitate their use and proper waste sorting or separation; they can be arranged in a straight line or in a hub-like configuration, and allow for the collection of paper, plastic, glass and cans.
