Materials

Materials We Accept

Our process is designed for a range of PV waste streams, from whole laminates to fine-grained silicon-bearing fractions. We work with different feed formats, impurity profiles and material qualities to recover valuable fractions for further processing.

Laminates

Whole or partially pre-treated PV laminates with different levels of glass adhesion and residual contamination.

With glass impurities Low-impurity Dismantling fractions
Laminates with glass impurities

Laminate sheets after pre-recycling or dismantling steps with partially attached glass residues and remaining contamination.

Typical condition:
Glass-bearing, partially pre-treated, residual contamination

Laminates without glass impurities

Laminates from pre-recycling stages with no or only minor glass residues attached. This category represents cleaner laminate fractions with lower surface contamination and more direct suitability for downstream processing.

Typical condition:
Low-glass, cleaner laminate fraction

Flakes

Shredded laminate flakes ranging from glass-bearing fractions to cleaner polymer-silicon material.

Glass-bearing Low glass Polymer-silicon flakes
Flakes with glass adhesion

Shredded laminate flakes with visible glassy adhesions and residual contamination. These fractions typically originate from early recycling or shredding stages and still contain mixed material characteristics. 

Typical condition:
Glass-bearing, mixed flake fraction

Cleaner flakes / low-glass flakes

Shredded laminate flakes with no or only minor glass adhesion. These fractions represent a cleaner polymer-silicon material stream with lower contamination and improved downstream suitability. 

Typical condition:
Low-glass, lower contamination

Granulates

Silicon-bearing granulates from mixed recycling streams to cleaner silicon-rich fractions.

Mixed granulates Silicon-rich Pre-recycling fractions
Mixed granulates

Shredded solar module material with residual glass and/or organic contamination, or granulates generated in upstream recycling steps.

Typical condition:
Mixed, glass-bearing, organic residues possible

Silicon granulates

Silicon-rich granulates with no or only minor glass and organic content. 

Typical condition:
Silicon-rich, lower contamination

Dusts & Fines

Fine silicon-based powders and dusts with varying levels of glass, polymer and inorganic contamination.

Mixed fines Silicon-rich dusts Process dusts
Mixed fines & dusts

Fine silicon-based powders with polymer and glass contamination, including exhaust or process dusts from PV recycling streams. 

Typical condition:
Mixed, glass-bearing, polymer contamination possible

Silicon-rich dusts & fines

Fine silicon-based powders without major glass or polymer contamination. 

Typical condition:
Silicon-rich, low contamination
