Sircular

Mission

Transform semiconductor waste into high-value silicon powder, driving a circular economy and sustainable innovation.

The challenge

The semiconductor industry faces a significant silicon waste problem, with nearly 75% of the material lost during production. Current recycling rates for Si and SiC are extremely low (around 5%), and existing recycling methods are costly and inefficient. Europe’s heavy reliance on imported Si and SiC from Southeast Asia creates supply chain vulnerabilities, exacerbating risks during global semiconductor shortages. A sustainable, circular approach to silicon waste recovery is urgently needed to enhance resource efficiency, reduce environmental impact, and secure a stable supply of critical raw materials.

The solution

We are developing an innovative method to recycle and repurpose silicon waste into high-quality silicon powder, leveraging ball milling and plasma techniques for controlled purity and composition. This Si-powder is in rising demand for laser-based additive manufacturing and high-tech applications. By utilizing existing waste streams, we aim to reduce resource consumption, enhance supply chain resilience, and create new market opportunities. Our approach transforms semiconductor waste into a valuable feedstock, enabling a circular economy and positioning us as a leading supplier of sustainable Si-powder.
