A novel approach, based on micro X-ray fluorescence (μXRF), was developed to define
an efficient and fast automatic recognition procedure finalized to detect and
topologically assess the presence of the different elements in waste electrical and
electronic equipment (WEEE). More specifically, selected end-of-life (EOL) iPhone
printed circuit boards (PCB) were investigated, whose technological improvement
during time, can dramatically influence the recycling strategies (i.e. presence of

Asbestos was largely used in the past by several countries all over the world. From 1900 to 1990 asbestos-containing materials (ACMs) were produced in large amounts for addressed to the production of insulation, flame retardant materials, as well as to improve mechanical and chemical characteristics of construction materials. The largest producer countries were Canada (chrysotile), South Africa (amosite, crocidolite), Russia (chrysotile), Finland (anthophyllite) and Italy (chrysotile). There are still some countries (e.g., Russia, China, Kazakhstan) where asbestos is mined and processed.
