Cascade approach on recycling for marble and granite product design

The present article presents the main results of a research project that aimed to establish guidelines on sustainable design for marble and granite products, a non-renewable material. The study was carried out within an association of 13 small and medium companies in Brazil. During the investigation it was identified a significant lack of literature on these materials which could support the design process, particularly regarding the issue of recycling. The study has unveiled the potential of applying in this sector the "cascade approach for recycling" where it is anticipated destinations to all possible wastage for the entire life cycle of a given product.
