Decorative Plates from Epoxydic Composites

Leather waste obtained in the leather industry represents a potential source of pollution for the environment, for plants and animals. The ecological treatment of this waste involves quite high costs and only companies with large production capacities can afford them. This paper proposes a method of transforming this waste into ash rich in chromium III and using it as a pigment (green), together with other substances, to obtain new materials. In this sense, it is proposed to use compounds that can incorporate and block the diffusion of the substances back into the environment. To achieve this, a mixture of epoxy polymers, biphenol A and biphenol F, will be used, in a 1:1 ratio, which after the polymerization reaction, with Ancamine 2686, will result in an inert mass. The polymer tiles can then be used as decorative elements for the facades of some buildings.
