Sustainable Source Studios (S3), an independent sustainability research and strategy practice, today announced the publication of its white paper “SOLAR RECYCLING REALITY — Millions of Old Panels Are Being Replaced. Where Does This Hazardous Waste Actually Go?” — a market survey of U.S. solar panel end-of-life practices. The paper’s central finding: almost none of what the United States calls “solar recycling” is closed-loop recovery. The dominant pathways, the paper concludes, are landfilling, offshoring, and what the author terms “camouflaging” — disposal disguised as recycling.

This infographic breaks down the core findings of the Solar Recycling Reality report, and includes citations.
The white paper, authored by sustainability-industry veteran Isaac Nichelson and built exclusively on regulatory records, independent market assessments, peer-reviewed research, and operators’ own public disclosures, documents seven findings, each footnoted in the paper to its public source:
- The U.S. cannot finish the job at home. The last domestic primary lead smelter closed in 2013. No U.S. facility today refines primary heavy metals from solar panel residues at industrial scale.
- The dominant U.S. pathway is foreign-owned end to end. Korea Zinc, through PedalPoint Holdings, operates four U.S. shredding facilities via evTerra Recycling. Metal-bearing concentrates from shredded American panels ship roughly 5,500 nautical miles to Korea for smelting, per corporate disclosures cited in the paper.
- The arithmetic requires American waste. Korea Zinc targets 120,000 tons per year of solar processing by 2030 at its Onsan smelter. Korea’s own projected solar waste is approximately 1,222 tons in 2025. The paper concludes the gap is filled with U.S. panels.
- The smelting endpoint has a documented contamination record. Peer-reviewed studies cited in the paper report stream sediments near the Onsan industrial complex with heavy-metal concentrations 3 to 1,302 times higher than urban areas, road-deposited sediment values among the highest reported in the world, and elevated blood-lead and urinary-cadmium levels in residents near the Seokpo smelter.
- Shredding releases what lamination contained. Studies cited in the paper found crushed panel material leached lead at 9.3 mg/L against a 5 mg/L regulatory limit; cadmium-telluride panels released approximately 73 percent of their cadmium in 30 days under simulated landfill conditions.
- Enforcement has begun on U.S. soil. The Texas Commission on Environmental Quality issued an April 30, 2026 Notice of Violation (TCEQ Complaint No. 455069) to a major solar recycler’s Odessa facility for failure to monitor stormwater discharges.
- A verification standard exists — and becomes mandatory in January 2027. Per the SERI R2 registry, only two North American facilities hold R2v3 Appendix G certification for solar panel recycling; only one operates at industrial scale. In January 2027, Appendix G becomes mandatory for every R2-certified solar recycler.
The paper also flags an economic-security dimension: silver, copper, aluminum, and silicon — all U.S. federal critical minerals as of November 2025 — consistently and permanently exit U.S. jurisdiction under the export model. Silicon is not recovered at all.
“This is not an anti-solar argument — it is the opposite,” said Isaac Nichelson, the paper’s author and founder of Sustainable Source Studios. “Solar has always been one of the most logical and elegant forms of energy production, and its efficiency keeps improving. That is exactly why the industry cannot afford an end-of-life chain that, as the cited record shows, leaches lead into groundwater and sends toxic material to overseas communities under the label of recycling. Our team was greatly encouraged to find that certified, traceable domestic recycling now operates at industrial scale, and that the R2 standard will require downstream traceability beginning in January 2027. We expect the next six months to define the leaders in solar’s end-of-life segment — and we believe the polluter-pays principle should apply here as it does everywhere else.”
The white paper closes with specific recommendations for solar asset owners, procurement teams, capital allocators, regulators, and ESG investors — including mandatory Appendix G certification in supplier contracts, per-shipment chain-of-custody documentation, and treating any recycling bid priced at or below landfill cost as a red flag for sham recycling.

About the research: The white paper is a documentary review of publicly available records, conducted in 2026 and current as of its July 22, 2026 publication. Sources comprise federal and state regulatory records (including Texas Commission on Environmental Quality enforcement filings and a Korean Ministry of Environment administrative order), the IEA PVPS Task 12 life-cycle inventory dataset (Report T12-32:2026, April 2026), the SERI R2 certification registry, peer-reviewed environmental studies, and the public disclosures of the operators discussed. No proprietary data, surveys, or interviews were used; every figure is footnoted to its source in the published paper. The research was self-commissioned and self-funded by S3; no third party commissioned, funded, or reviewed it prior to publication.
