A new study has proposed a cost-effective way to recycle solar panels to help
In an article published by a group from the UniversityNew South Wales last week, researchers described the process of collecting and extracting valuable materials from solar panels to test whether it is technically, economically and environmentally feasible.
The process includes collecting solar panels,removing the aluminum frame from them, shredding the cells and using electrostatic separation to collect valuable materials including silver and copper, reducing the weight of the panels to 2-3% of their original weight.
The recovered material will then be sent directly to the refinery for cleaning and processing.
Dr. Pablo Diaz, lead author of the study,said it showed the possibility of launching a small enterprise capable of operating 1,000 tons of solar panels per year. This is roughly equivalent to 50,000 panels per year, or about 4,100 panels per month.
This method does not include the useno chemicals, it does not emit any pollutants or hazardous pollutants. It produces dust from crushing panels, but there are dust collectors,” Diaz said.
There are currently very few in Australiaopportunities to recycle and recycle solar panels when they reach the end of their useful life. This is seen as a growing issue as high levels of rooftop solar and proposals for large-scale solar farms mean that more panels will reach the end of their useful life.
In a report by the International Agency forRenewable Energy Report 2016 found that large and early users of solar PV can expect the most waste from older systems.
Australia is projected to generate 145,000 tons of photovoltaic waste per year by 2030, with the US expected to produce 1 million tons per year and China to 1.5 million tons.
