The Stokkermill Automatic Series
Solar3000

The recycling line for solar and photovoltaic modules allows for the recovery and reuse of materials found in discarded panels, such as silicon, glass, aluminum, plastic, and wiring. Thanks to an automated and advanced industrial process, each module is precisely dismantled, yielding reusable resources such as glass, silicon powder, aluminum, plastic, and copper. The system minimizes manual intervention and energy consumption (less than 1 kWh per module), ensuring high efficiency and reduced environmental impact. The technology allows for the treatment of polycrystalline, monocrystalline, and even non-standard sized modules, optimizing operating costs and improving the quality of recovered materials.
Efficient recovery, minimal impact.

XRS Delaminator Mill
The Stokkermill XRS delaminator mill allows for the mechanical separation of layered materials, releasing the silicon/glass fraction trapped in the EVA layer. Thanks to a controlled crushing process, the silicon is recovered in fine form together with a fraction of thin glass and any precious metals. Thanks to its specific design and the use of special materials, wear is extremely low, with minimal downtime and high operational continuity.

Recovered Materials

Turning Solar Panels into New Resources

Aluminum - Glass - Silicon - EVA - Copper

Aluminum

Stokkermill eliminates the need to remove the aluminum frame, speeding up processing. The aluminum output is furnace-ready, clean, and compliant with End of Waste standards, maximizing value while minimizing energy use.

High Recyclability Low Environmental Impact

Glass

Recovered glass comes in multiple grain sizes and qualities. The larger fraction is very clean, while finer particles are still suitable for use in the ceramics industry. Both fractions have low iron content.

Primary Volume Consistent Quality

Silicon

The finest glass fraction contains silicon along with traces of silver and other metals. It is already used across various industrial sectors and still represents a high-value opportunity for further recovery.

High-Tech Value Fine Fractions

EVA

Polymer fractions, including back-sheet and EVA, are recovered free of glass and contaminants. Thanks to their good calorific value, they are used as alternative fuels.

Encapsulant Controlled Separation

Copper

Copper is a strategic, valuable, and reusable metal. Stokkermill leverages 20 years of experience and specialized technologies to maximize recovery and produce high-quality material efficiently.

High Yield Proven Supply Chain

alluminum

The Stokkermilll recycling system does not require removal of the aluminum frame, drastically reducing panel processing time. The quality of the output materials is excellent.Aluminum, for example, will be oven-ready free of any pollutants and of the correct size, suitable for downstream metallurgical processing. Thus, maximumvalorization of the material and minimal energy impact during the final processing.

glass

The glass resulting from the treatment operations is of different grain size and quality. Larger size glass is clean, has a low iron content and is reused by the glass industry. A smaller size fraction still finds use in the glass or steel industry, where it can be used for the production of high quality silicon steels.

silicon

The thinnest fraction of glass will contain silicon, traces of silver and other metals. While it already finds wide application in a variety of industries, it is a fraction yet to be discovered in terms of value and recovery opportunities.

plastic

The polymeric back-sheet and EVA (Ethylene Vinyl Acetate) fractions, are recovered at the end of the process. They are fractions substantially free of glass and other pollutants and characterized by good calorific value such that they find applications as alternative fuels.

copper

During the solar panel recycling process, copper represents one of the strategic recoverable metals, mainly found in electrical conductors and, to a less significant extent, in the module's internal connections. Although it constitutes only about 1.2 percent of the total weight of a standard panel (about 12 kg out of a ton of treated panels), copper has high economic value and high potential for reuse in industry.

Recycling Process

Load → Shear → HMS → Separation → Magnetic → MFS → XRS → Final output

Load

Feeding of panels with or without frames and dosing to the shearing machine. Removal of junction box if present.

Shear

First volumetric reduction, panel opening, and partial or total detachment of the aluminum frame.

HMS

Delamination of glass–EVA–cells, release of metals, production of main fractions: coarse/fine glass and aluminum proler.

Separation

Separation of heavy fractions (glass) and light fractions (EVA, powders, fine glass).

Magnetic

Removal of ferrous residues using an Overbelt magnetic system.

Final Output

EOW aluminum dross, coarse/fine glass, glass+EVA mixture, micro-metal residues, and silicon powders.
