Material made from 65% recycled shells such as oysters, mussels or scallops from marine waste, coupled with a mineral matrix without the addition of elements of petroleum origin. The molluscs are recovered, minced and used to make slabs. Depending on the type of shell or the size of the sequins, the material can thus take on different textures. It is mainly used in the production of worktops and can be customised by adding natural pigments.
