Electrostatic separation can assist in the recycling of waste photovoltaics, but the parameters for an optimal separation are still uncertain. Zuser A, Rechberger H (2011) Considerations of resource availability in technology development strategies: the case study of photovoltaics.
Electrostatic separation has an influence in most of the materials present in waste silicon photovoltaics. This process may assist in the recycling of waste PV.
Moreover, the mass distributions in the three pans as a function of the tested parameters are shown in Supplementary Table 7. The key conclusions from this study are as follows: Electrostatic separation is able to segregate the metallic fraction of waste photovoltaic panels. Metals tend to concentrate in the first separation fraction (conductor).
The objective of this study is to evaluate the use of electrostatic separation technique to segregate some of the main materials present in silicon-based photovoltaic modules: silver, copper, silicon, glass, and polymers from the back sheet and encapsulating material.
As early as 2012, the latest revision of the EU Waste Electrical and Electronic Products Management Regulations took the lead in bringing solar PV modules into the scope of management. Solar cells are officially classified as electronic waste and require efficient recycling [24, 25].
Solar cells have been classified as electronic waste in the revised Waste Electrical and Electronic Equipment (WEEE) Directive published by the European Union in July 2012 . Therefore, the problem of the electronic waste generated by scrapped solar cells cannot be ignored. Solar-cell scrap and cumulative scrap in China in 2005–34
