Circular Silicon stands for a sustainable production of metallurgical silicon.
We produce our green silicon by
recycling silicon waste from the solar industry.
We recylce silicon from PV-waste in Europe and Silicon Kerf in Asia. Our Products is metallurgical silicon, which we sell as pellets, powder or lumps.
40% production waste as Kerf
Quartz + Carbon
Ingots & Crystals
(purity > 60%)
solar panel waste
We produce metallurgical silicon with the lowest carbon-footprint in the industry. Our product portfolio includes powders, pellets, and lumps. Our products serve the complete range of silicon applications.
To guarantee the quality of our products, we are in close contact with our customers.
For chemical products, ceramics, and lithium-ion batteries.
Sizing: < 1mm
Silicon content: 98.5 - 99.99%
As an alloying element for aluminum alloys and ferro-alloys. Our pellets have high solubility and can substitute ferrosilicon (FeSi) as well as silicon lumps.
Sizing: 15-50 mm
Silicon content: 98.5-99%
The standard commodity for every industry.
Sizing: 10-100 mm
Silicon content: 98.5-99%
Silicon is an indispensable raw material for our society: As an alloying element, in chemical products or in solar cells and computer chips. Yet production is energy-intensive and associated with indirect and direct CO2 emissions. Our goal is to save CO2 emissions from primary production by recycling silicon waste streams.
Circular Silicon was founded in the year 2023 by a group of environmentally conscious engineers and economists, with the goal to build a silicon recycling plant in Europe.
We saw an opportunity to adress the growing issue of solar panel waste while also reducing the demand for low carbon silicon. By developing our own technology, Circular Silicon is able to effectively recylcle and recover silicon from end-of-life panels. We are currently building our first pilot line in Germany and are aiming to establish an industrial line in 2023.
We are also localted in Hong Kong, which offers us a strategic positition to access the Chinese Kerf Waste Market and use the opportunities offered by the government initiative to promote the recycling of PV module waste.
With a strong commitment to reducing waste and promoting sustainable energy, Circular Silicon is at the forefront of the movement towards a greener future.
