The path is inserted in the “Raw Matter Ambassadors at Schools” project (RM@ Schools).

More than 20 dissemination products collected along 4 years of activity are examined. Due to the general character of the lesson, the related dissemination products deal with several topics including ethical and geopolitical issues consequent to the exploitation of natural resources, the analysis of the materials composing mobile and recycling strategies, and the researches on the substitution of critical materials with environmentally friendly alternatives.
