ROSI

What ROSI does

ROSI is a French deep-tech and industrial recycling company founded in 2017 in Grenoble that operates the world's first commercial-scale end-of-life photovoltaic (PV) module recycling line. The company applies a proprietary combination of pyrolysis, mechanical sorting, and mild chemical processes to recover high-purity silicon, silver, copper, aluminum, and high-transparency glass from decommissioned solar panels and from PV manufacturing scrap, including kerf silicon powder lost during wafer sawing. Recovery rates are reported at up to 95-99% across the active materials, with less than 1% disposable waste. The company's technology platform underpins both its recycling service operations and its broader ambition to enable a European circular economy for PV and adjacent materials industries.

ROSI serves a diversified industrial B2B customer base: PV manufacturers (e.g., Solarge, Yingli Solar) seeking sustainable manufacturing-scrap recycling; glass manufacturers (AGC Glass Europe) sourcing recycled glass cullets; precious metals refiners (METALOR) receiving recycled silver; and national eco-organizations and collection partners (Soren in France, SENS eRecycling in Switzerland, Waste Experts and CEF in the UK) channeling end-of-life panels into ROSI facilities. The company generates revenue through transaction-fee-based recycling services and the sale of recovered circular materials (silicon, silver, copper, aluminum, glass), with multi-year enterprise contracts and quote-based pricing rather than published price lists.

The operating footprint comprises ROSI Alpes (operational since June 2023, Saint-Honoré, France, ramping to 10,000 tonnes/year), ROSI Iberia (under development in Teruel, Spain, 10,000 tonnes/year target under the EU Innovation Fund's INSPIRE-PV project), ROSI Elbe (Germany, site director appointed March 2024), and the planned ROSI@RHE project at Evonik's Rheinfelden site. ROSI has raised over €30 million cumulatively across EIC grants, Bpifrance, a Series A in 2022, and a €20M+ Series B in April 2026 led by InnoEnergy with CMA CGM, EIC, and G3T. The company is recognized as one of Europe's highest-potential deep-tech scale-ups (EIC Scaling Club, French Tech 2030, World CleanTech StartUPs Awards 2024) and operates in a structurally expanding market projected to reach 60 million tonnes of cumulative global PV waste by 2050.

Revenue model

1. Recycling Services for End-of-Life Solar Panels: ROSI charges fees for recycling end-of-life photovoltaic panels collected by partner organizations. Revenue comes from processing fees paid by eco-organizations (Soren), collection partners (SENS eRecycling, Waste Experts), and direct industrial customers. The company recovers high-purity materials that are sold as secondary raw materials.
2. Recycling of Manufacturing Scrap: Provides high-value recycling solutions for PV manufacturers to improve sustainability of their production by reducing scrap materials and out-of-specification products. Generates revenue from processing fees and material recovery.
3. Sales of Circular Materials: ROSI sells recovered high-value raw materials including high-purity silicon, silver, copper, aluminum frames, and high-transparency glass cullets to industrial customers. Materials are compatible with high purity requirements and low impact targets of PV manufacturers and other industries.

Core offering

ROSI develops and operates proprietary industrial recycling processes that recover high-purity silicon, silver, copper, aluminum, and glass from end-of-life photovoltaic modules and PV manufacturing scrap (including kerf loss). The company sells these recovered secondary raw materials back to PV manufacturers, glass producers, and precious-metals refiners while offering paid recycling services to eco-organizations and PV asset operators across Europe.

Product overview

ROSI offers a comprehensive circular economy platform for the photovoltaic industry, consisting of recycling services (end-of-life solar panels and manufacturing scrap) and a portfolio of recycled material products. The platform is supported by multiple industrial facilities across Europe (ROSI Alpes in France, ROSI Iberia in Spain, ROSI Elbe in Germany) and the INSPIRE-PV project. The product portfolio includes circular materials: high-purity silicon, silver, copper, aluminium, glass, and advanced materials. ROSI operates the world's first industrial-scale plant capable of recovering high-purity silicon and silver from end-of-life photovoltaic modules.
