OUR COMMITMENT

Eliminate the concept of waste
 

WHO WE ARE

Our name is Nuvosil which means “new silicon”

CIRCULAR ECONOMY

By use of new technology, we reprocess silicon waste into high value materials

OUR GOAL

Trigger a transition from Minimizing to Monetizing waste

About Nuvosil

The solar industry consumes almost half of the silicon raw materials used in the production of solar cells. Nuvosil is focused on innovating the remanufacturing of the silicon waste to valuable end-market industrial applications.  Nuvosil aims to catalyze the solar industry to be a fully circular, or closed-loop ecosystem with all materials staying in endless cycles of value.

Problem

 

PRODUCTION OF SILICON WAFERS generates ~40% of the starting material as waste (swarf)

Silicon metal particle waste (swarf) results from the sawing process and is recovered by filtering.

Solution & Value Chain

NUVOSIL and our Partners have co-developed a low energy recycling process.
A patented and exclusive screw extruder technology allows silicon and aluminum waste to be remanufactured into Low Energy Master Alloy rods.

Product

Low Energy Master Alloy

Nuvosil’s Low Energy Master Alloy (LEMA) rods – are produced using an environmentally friendly and novel screw extrusion process eliminating the need for high energy intensity heating or re-melting. These master alloy rods are made up of silicon and aluminum. Compared to conventional alloying processes, the LEMA technology consumes 90% less energy, costs less per processed unit and offers a cleaner end-product.

CLEANER – higher purity & less CO2

CHEAPER – lower cost

GREENER – 90% less energy

Innovation

The key component of the Low Energy Recycling (LER) process is a screw extruder unit developed and patented by Hydro in collaboration with NTNU.  The technology was initially developed for use on different aluminum recyclable materials.  In 2018, Nuvosil, Hydro, SINTEF and NTNU engaged in a R&D project to test the LER process using a combination of aluminum and silicon and the lab-scale extruder at NTNU. This novel application was verified in 2019 with very promising results.  Consequently, in early 2020 Nuvosil and Hydro initiated the LER Pilot project.  The LER Pilot project aims to design, build, test and qualify an industrial-scale extruder unit and associated processes.  The Pilot project is the last development stage before the industrial phase and commercialization planned for 2022. Once launched, Nuvosil will focus on the combination of silicon and aluminum, while Hydro will focus on aluminum and other non-silicon materials applications.

News

Nuvosil and Hydro

In August 2020 Hydro and Nuvosil were granted financial support by ENOVA for the Low Energy Recycling (LER) Pilot project, in the amount of MNOK 9,6. The project is a collaboration between Hydro and Nuvosil aiming to verify scalability of the Low Energy Recycling process for use on a combination of silicon and aluminum, and aluminum either alone or in combination with non-silicon materials. The total budget is MNOK 18,3 and the project shall be completed by year end 2021. In addition to Nuvosil and Hydro resources, the LER Pilot project is supported by a strong team of technology and industry partners: SINTEF, NTNU, Reifenhauser GmbH and CEMTEC GmbH.
