Silicon Recovery
We develop routes to recover silicon-bearing fractions from PV recycling streams that are often not sufficiently utilized today.
Mining what solar leaves behind.
We process your silicon-rich PV waste streams to maximize material value recovery.
Circular Silicon
Recycling Solutions for End-of-Life Solar Materials
Recovering value from end-of-life solar
Silver & Copper Value
Our process targets not only silicon, but also silver- and copper-containing fractions from end-of-life solar materials.
Industrial Implementation
Circular Silicon combines process development, laminate processing and industrial scale-up with applied research.
Designed for real PV recycling streams
We work with a range of silicon-bearing PV materials, from larger laminate fractions to fine-grained powders and granulates. Our processes are designed to handle different feed formats, impurity profiles and material qualities.
Laminates
Whole or pre-treated PV laminates with various levels of glass adhesion or residual contamination.

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

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

Dusts & Fines
Fine silicon-based powders and dust fractions with varying levels of glass, polymer and inorganic contamination.
View detailsAdvancing silicon recovery from solar residues
Circular Silicon is involved in research and industrialisation projects focused on two key goals: industrialising the recovery of silicon from solar module residues and improving the separation of silicon and silver from silicon-rich powders.
More than a concept
Circular Silicon works at the intersection of recycling technology, industrial implementation and applied research. Our current setup combines laminate processing activities, development of a silicon recovery line and participation in industrialisation-focused research projects.
