Comstock, the only fully integrated end-to-end solar panel processor in the United States, has achieved a significant industry milestone by earning both the R2v3 to Appendix G and RIOS certifications. This accomplishment positions Comstock Metals as the first solar panel processor in the world to be certified under the newly added Appendix G standard, which was introduced in January 2024. Due to the recent availability of accreditation for this addition, Comstock’s recognition reflects both its leadership and early adoption of the highest recycling standards.
Fortunato Villamagna, President at Comstock Metals LLC, stated, “Our company is dedicated to environmental sustainability and has achieved high standard certifications. We have developed a closed-loop model where even floor sweepings and employee PPE are processed into market-ready products. I am very proud of what we have achieved.”
Evelyn Butler, Vice President of Technical Services at the Solar Energy Industries Association (SEIA), stated, “Solar panel recycling is a win-win-win – good for consumers, the economy, and our planet. We congratulate Comstock Metals on this achievement – one of our Preferred Recycling Partners – and we look forward to continuing this partnership for the benefit of the entire solar energy industry.”
The company is known for pioneering advanced solar panel processing through its proprietary delamination methods, enabling it to recover and recycle 100% of each panel into commodity-ready materials. This includes the complete recovery of glass, aluminum, and fines, setting a new benchmark for sustainable solar waste management. These certifications further validate Comstock’s commitment to responsible recycling and reinforce its role as a leader in the circular economy for clean energy technologies.
