Over the next decade, the number of unserviceable photovoltaic solar panels will increase dramatically, reasonably tens of millions only in Italy. How can we dispose of the dismissed solar panels and recover their most precious raw materials? This patent has developed a method and plant to effectively separate glass, silicon, aluminium, silver and copper from discarded photovoltaic solar panels. The recovery of raw materials from photovoltaic solar panels is difficult because they are composed of different layers of materials, tightly sandwiched together in order to resist to external weather conditions. The method and plant described in this patent are an effective means of separating the materials present in the panels, such as glass, copper, silver, aluminium and silicon. The panels go through a sequence of treatments that use easy to find and convenient reagents. It does not require sophisticated machinery. The use of such a process will make material recovery convenient and will avoid the disposal of the panels in landfills, where hazardous materials may be dispersed in the environment.

  • Radial discharge plasma for the treatment of contaminated liquids

    Removal of harmful recalcitrant organic substances (anthropogenic or otherwise) from water and aqueous matrices like leachate is indispensable for ensuring public health and safety, and for environmental protection. The choice of technology for contaminants removal is case specific and often[...]

  • Connector for timber walls

    This patented anchoring system is ideally used in timber construction. Its special shape and material are ideal to connect wood walls or to anchor them to concrete foundations, even in high seismic risk areas. This invention is an X-shaped steel[...]

  • Improved solar panel recycling

    Over the next decade the number of unserviceable photovoltaic solar panels will increase exponentially. More efficient methods designed to separate the many materials that make up a panel must be developed so that they do not end up discarded in[...]
