Eco-innovative products and technologies based on the recycling of certainwastes from tanneries and nonferrous metals industry for the transition of the leather industry to a circular economy model

Abstract

This paper presents experiments of recovery/recycling/reuse of as much tannery waste as possible to obtain new auxiliary materials with high added value and low eco-aggressiveness intended for leather processing. The paper also deals with conversion of waste difficult to manage (some of which is unrecyclable) from the non-ferrous metal industry into factors for increasing the ecoefficiency of the leather industry.
