As China's photovoltaic (PV) industry enters a phase of large-scale decommissioning, the environmental disposal and resource recycling of waste PV modules have become critical issues to be addressed urgently in the industry. Relying on independently developed PV panel crushing and recycling technology, Jiangxi Mingxin has achieved full-value recycling of core components such as glass, metals, and silicon materials, providing a replicable circular economy model for the green and low-carbon development of the new energy industry.
According to industry data, China's PV installed capacity has exceeded 1000 gigawatts. Based on a 25-year design lifespan, the country will face a decommissioning peak in 2025, and the cumulative scale of decommissioned modules is expected to reach 1 million tons by 2030. Last year, six ministries and commissions including the National Development and Reform Commission issued the Guiding Opinions on Promoting the Recycling of Decommissioned Wind Power and PV Equipment, which clearly stated the need to break through key technologies for resource recycling and establish a standardized recycling system. Jiangxi Mingxin's recycling technology is a positive response to this policy orientation.
In practical application, the company has realized efficient recycling of 70% of the glass component in PV panels through precision crushing and separation technology. The processed recycled glass can not only be reused in PV module production to reduce quartz sand resource consumption but also be widely applied in fields such as architectural curtain walls and sound insulation materials, effectively alleviating the pressure of landfill disposal. In the metal recycling segment, the company has focused on overcoming purification technologies for aluminum frames, copper wires, and silver electrodes. Among them, recycled aluminum saves over 95% of energy compared to primary aluminum smelting, and high-purity recycled copper can be directly used in the manufacturing of wires and cables, resulting in significant annual carbon emission reductions.
The most technologically breakthrough aspect lies in the silicon material recycling system. Through processes such as acid cleaning and purification, the purity of recycled silicon materials meets PV-grade standards. The re-manufactured solar cells can re-enter the core link of the industrial chain, with a recycling value of approximately 1,500 US dollars per ton. Meanwhile, high-purity recycled silicon has also been extended to high-end application fields such as semiconductor substrates and silicon alloys, realizing a "from module to module" closed-loop cycle.
Industry experts pointed out that Jiangxi Mingxin's technical path has verified the economic viability of the PV recycling industry. Based on the current recycling scale, each ton of decommissioned modules can yield 700 kg of glass, 200 kg of aluminum, and 50 kg of silicon, with a comprehensive recycling value exceeding 4,000 yuan, significantly higher than the cost of traditional landfill disposal. This model not only eases the tight supply of primary resources but also provides technical support for China's PV products to cope with international carbon footprint barriers.
With the advancement of the "dual carbon" goals and the implementation of equipment renewal policies, the PV recycling market is expanding at an accelerated pace. A relevant person in charge of Jiangxi Mingxin stated that the company will further expand its recycling capacity, striving to achieve an annual processing scale of 50,000 tons of decommissioned modules by 2026, and contribute to building a full-lifecycle green supply chain for the PV industry.
