Venetian innovation for a more sustainable future
In the overview of renewable energy, an important turning point comes from Italy. The Venetian company 9Tech has developed a revolutionary method for recycling solar panels, achieving 99% efficiency without using toxic chemicals. This innovation could be a turning point both for the photovoltaic industry and for environmental protection.
Why is it necessary to recycle solar panels?
Solar panels are designed to last for over 30 years, despite adverse weather conditions. However, at the end of their life cycle, getting rid of them is a big challenge. Mainly made up of crystalline siliconthey also contain silver and copper conductors, as well as adhesive polymers to protect them from moisture. These materials make the recycling process complex and expensive.
According to recent data fromInternational Renewable Energy Agency (IRENA)by 2050, waste from solar panels is expected to reach 78 million tons universe. It is therefore essential that recycling is dealt with effectively to avoid negative environmental impacts.
The innovative process of 9Tech
The 9Tech pilot site, based in Venice, has implemented a process that begins by removing the aluminum frames and tempered glass from the panels. This leaves a structure made up of silicon wafers, metal conductors and adhesive polymers. After that, this “sandwich” is heated in a combustion oven at a temperature above 400 degrees Celsius. This allows the transfer of polymers without releasing toxic gases.
An advanced filtration system captures combustion residues, while the heat generated is recovered and reused in the process. This procedure avoids the use of aggressive chemicals, often used in traditional methods, which can release harmful substances into the environment.
Recovery of precious metals
After the burning stage, the remaining materials are subjected to a series of sieves and mechanical separation. The copper produced through physical processes, while theargento it is separated from silicon using organic acids and ultrasonic methods. This method avoids the use of toxic acids such as nitric or hydrofluoric acid, which are commonly used in industry.
Second Marco Bianchiexpert in renewable energy, “This technology not only reduces the environmental impact of recycling processes, but also allows us to recover materials of high economic value, helping to make solar energy even more stable.“.
Impact and future opportunities
The innovation proposed by 9Tech offers a concrete solution to the growing problem of photovoltaic waste. In addition to reducing the environmental impact, this method could have a positive effect on the circular economy, encouraging the reuse of valuable materials and reducing dependence on virgin mineral resources.
The financial implications are significant. With the increasing demand for solar energy and the increase in panels coming out gradually, companies like 9Tech could be in a strategic position in the recycling market , attracting investments and creating new jobs in the green sector.
Collaboration and expansion opportunities
The method resourceful with 9Tech has raised the interest of other companies in the renewable energy sector, as well as public institutions and investors who are aware of sustainable technologies. The company is evaluating the possibility of expanding its activities, repeating the recycling model in other sectors both in Italy and abroad.
In addition, partnerships with research centers and universities could accelerate the development of further technological developments, making the process even more efficient and competitive.
Conclusions
The solution proposed by 9Tech represents a major step forward in the field of renewable energy. By reducing waste almost completely and eliminating the use of hazardous chemicals, this technology could become a benchmark for the global photovoltaic industry.
For investors and real estate operators interested in renewable energy, this innovation offers new opportunities. Investing in companies that promote sustainable technologies not only contributes to the protection of the environment, but can also guarantee attractive returns in the medium and long term.
As he says Laura Rossifinancial analyst specializing in renewable energy, “the adoption of these technologies can have a positive impact on both the environment and investors’ portfolios.” It is essential to monitor these developments to seize emerging opportunities in the market.”
