Granite scraps and abandoned quarries for future eco-innovative scenarios in Sardinia 

Within the framework of the Redirect research project and, more specifically, of the study strand carried out by UNISS, the article entitled 'Granite scraps and abandoned quarries for future eco-innovative scenarios in Sardinia' was presented. The publication summarises the first results and presents the next steps to achieve the project's objectives (WP 7). In particular, it highlights the reuse potential of granite scraps that, if properly processed, could feed

a)  the ceramics industry for the feldspathic component of granite obtained after crushing and magnetic separation;

b) the construction industry, through building components for high value-added construction solutions, such as thin slabs for open-jointed ventilated façades;

c)  production chains in industrial symbiosis aimed at the recovery, recycling and reuse of waste materials.

The valorisation of secondary raw materials is an opportunity to reduce the erosion of natural resources through new scenarios for eco-innovative production processes and to regenerate, from an environmental, aesthetic and functional point of view, the landscape wounds of mining.
