Cardboard waste management systems are a customised, neat and environmentally friendly solution to encourage vending users to separate their waste. They are made of cardboard, fully printable and surface-treated to be water-repellent (both internally and externally). They are therefore wear-resistant and made to last. Each internal space of the differentiators contains a solid waste bin, easily accessible from the back of the structure itself. The structure rests on wheels, making it easy to empty the bins, and the holes for waste collection are protected by metal seals.
