These processes are designed not only for efficiency but also for environmental responsibility, ensuring that end-of-life photovoltaic modules are treated with minimal ecological impact while maximizing resource recovery.
At the core of this capability is the ability to recover high-purity materials—including glass, metals, silver, copper, and solar-grade silicon—through fully integrated process design. From furnace technology to advanced separation systems and IP-driven know-how, the German foundation ensures precision, consistency, and scalability. This strong technology backbone directly impacts India by enabling the deployment of globally proven recycling solutions that can be localized and industrialized at scale, supporting the country’s growing solar capacity while building a sustainable, circular ecosystem for the future.
Requisimus has built strong on-ground capabilities in India through over three years of strategic partnership, focused on enabling seamless technology transfer and effective localization of advanced PV recycling solutions. This is supported by comprehensive EPC expertise covering engineering, project management, software integration, commissioning, and ongoing operations and maintenance. By aligning global technology with local execution frameworks, Requisimus ensures that complex recycling systems can be deployed efficiently within India’s industrial landscape.
A key strength lies in the localization of critical equipment and systems—including pellet press units, furnaces, dryers, crushers, belt conveyors, and rare-material separation technologies—supported by a robust vendor development network. This enables competitive pricing while ensuring manufacturing readiness within India. With a single-window execution model, Requisimus offers end-to-end project delivery, facilitating industrial-scale deployment of complete recycling lines for Indian PV manufacturers. This integrated approach not only accelerates adoption but also strengthens India’s capability to build a self-reliant, circular solar ecosystem.
Requisimus has developed a robust PV recycling ecosystem by integrating multiple advanced, proven, and scalable technologies, built on more than a decade of German R&D and adapted for industrial deployment in India. At the core of this system is a combination of thermo-mechanical, chemical-free processes that enable efficient dismantling and high-purity recovery of materials. Controlled low-energy delamination softens encapsulant layers such as EVA and POE, allowing clean separation of glass, cells, and back-sheet without the use of solvents. This is complemented by precision glass separation systems that ensure minimal micro-fractures, enabling recovered glass to be directly reused in industrial applications.
The process flow further incorporates silicon recovery and refinement through mechanical separation and proprietary purification methods, making the recovered material suitable for downstream wafer and ingot production. Multi-stage metals extraction techniques—including shredding, magnetic sorting, eddy-current separation, and fine-particle recovery—ensure efficient extraction of copper, silver, aluminium, and other valuable materials at high purity levels. Specialized back-sheet processing technologies enable safe handling of fluorinated materials, while localized India-ready systems for rare-material separation enhance recovery of fine particles such as silver. Integrated automation and IoT-enabled monitoring bring consistency to operations, ensuring high throughput, recovery rates of up to 98%, and minimal downtime.
With a clear focus on closing the loop in the solar value chain, Requisimus is enabling a circular economy for photovoltaic modules, ensuring that solar energy remains not only renewable but also resource-efficient and environmentally responsible.
