New industrial plant concept for end-of-life PV panel recycling

Equipment moves the treated panel to one of two glass detachment lines, where the glass is heated up by infrared lights and then removed through a vibrating steel blade. “The action of the vibrating knife and the detachment from the sandwich crush the glass that falls on a lifter and moves on to the next area,” described Tialpis Ramon.
After this process is finished, a rubberized cup belt transfers the glass to the screening department. The purpose of the screening is to eliminate fine ( > 10 mm) glass elements and any sandwich residues to obtain glass sized in between 2 mm and 10 mm. These two products are then bagged straight into big bags on a pallet to be then moved to the stock with a forklift.
In order to get a premium glass, the 2 products should then be properly kept and optically sorted to identify and decline non-transparent particles. “After the optical sorting, the final top quality glass with a 2-10 mm size is straight stored in a 50-ton capability silo. From here, it is possible to fill straight the trucks for final delivery to the consumers,” stated Ramon.
The last action consists of an offline maker that is manually fed cabling at as much as 150kg/hour to deal with and draw out copper with 99% pureness, and plastics that can be used for extrusion. The entire procedure, according to the company, is environmentally suitable, as it is carried out without emissions into the environment and without making use of water. The recovered aluminum can be used in remelting procedures for different markets such as automotive and building and construction, while the top quality extra-clear glass can be used in the container glass and flat extra-clear glass industry.
According to its designers, the whole procedure has a low energy consumption of about 1kW per panel. “It is performed with only two employees and the payback time is about 2 years,” the spokesperson explained.

” We have actually established a brand-new innovation to recover the most considerable components of photovoltaic panels such as aluminium profiles, copper cables, and glass,” Vera Ramon, who is accountable for energy at Tialpi Srl, told pv publication. “Our next action, which is the second stage of our task, will be completing the advancement of the processes for dividing the backsheets from the wafer of silicon, which will make it possible to recuperate 100% of a modules weight. For the very first stage, the business has actually currently secured a patent while for the second the patent is still pending.”
The 2nd phase of the task is presently under advancement at the businesss facility in Mottalciata, in the Italian northern province of Biella. The commercial plant will recycle photovoltaic panels throughout numerous steps.
The procedure at first moves the panels into the line from two vertical stock containing about 25 panels each via a gripping system with pneumatic pistons that presses on the four aluminum boundary profiles, which are then moved through wheeled containers to the stock with a forklift. “The port cables are cut by hand with a simple scissor and the cable televisions will be bagged manually directly into huge bags on a pallet to be then transferred to the stock with forklift,” said Ramon. “Then the edges of the aluminum frame are cut by methods of four miter saws ran instantly and the dust generated will be drawn up with a vacuum and bagged straight into 25 kg bags.”

” We have established a new technology to recuperate the most substantial parts of photovoltaic panels such as aluminium profiles, copper cable televisions, and glass,” Vera Ramon, who is responsible for energy at Tialpi Srl, informed pv magazine. The procedure initially moves the panels into the line from two vertical stock consisting of about 25 panels each through a gripping system with pneumatic pistons that presses on the 4 aluminum boundary profiles, which are then moved through wheeled containers to the stock with a forklift. Machinery moves the treated panel to one of two glass detachment lines, where the glass is heated by infrared lamps and then removed by means of a vibrating steel blade. The recuperated aluminum can be utilized in remelting processes for different industries such as automobile and building and construction, while the high-quality extra-clear glass can be utilized in the container glass and flat extra-clear glass industry.
The job started in 2012 with the objective of screening and developing innovative technologies for 100% recycling of end-of-life photovoltaic panels in an economically and ecologically sustainable method.

The job began in 2012 with the aim of screening and developing innovative technologies for 100% recycling of end-of-life photovoltaic panels in an economically and environmentally sustainable method. The project leader was Tialpis moms and dad company, Sasil, a system of Italian mining business Minerali Industriali, in collaboration with glass maker Stazione Sperimentale del Vetro di Murano (SSV) and the consortium PV Cycle.

Italian startup Tialpi is establishing a process to recycle end-of-life solar panels that guarantees to recover 100% of a PV modules weight. The new plant style is currently being checked at the companys center in the Italian northern province of Biella.Italian start-up Tialpi Srl has established a brand-new principle for photovoltaic panel recycling plants that may supposedly help recycle a minimum of 85% of a photovoltaic panels weight.
