CRRC's Sheyang Facility Completes 110-Meter Blade With Reversible Chemistry at Its Core

From Rail Giant to Wind Recycling Pioneer

CRRC, best known as the world's largest manufacturer of rail equipment and listed on the Shanghai Stock Exchange under ticker 601766, unveiled an 110-meter recyclable wind turbine blade at WindEnergy Hamburg in September 2026. Produced at the company's facility in Sheyang, Jiangsu Province, the blade achieves a material recovery rate exceeding 95% for key raw materials. CRRC described the milestone as a significant step toward commercial-scale recycling of ultra-large wind turbine blades.

The Scale of China's Decommissioning Problem

The blade's development has emerged against the backdrop of a mounting disposal crisis. China's earlier generation of wind turbines is aging out of service at an accelerating pace, and industry estimates project that more than 30,000 turbines will have been retired by 2030, representing 44.73 gigawatts of capacity. The waste generated by that wave of decommissioning is forecast to reach 947,900 metric tons of wind-related solid waste.

Meanwhile, new onshore and offshore wind installations in China are expected to exceed 470 gigawatts in the years ahead, compounding the long-term scale of the challenge. Turbine blades lie at the heart of the problem. Traditionally made from thermoset composite materials that resist separation, they have historically resisted recycling efforts and frequently ended up in landfills at the conclusion of their operational lives. CRRC characterized recovering and reusing materials from these blades as a critical challenge facing the entire wind industry.

Reversible Chemistry as the Central Innovation

The 110-meter blade is built around a recyclable material system whose core component is what CRRC describes as a high-efficiency, debondable infusion resin. The key mechanism is reversible chemical debonding technology, which allows the resin to be efficiently separated from reinforcing fibers once a blade has reached the end of its service life. CRRC said the blade is designed to fully satisfy demanding performance requirements covering high strength, stiffness and fatigue life while still enabling that separation process.

Once disassembled, the recovered resin and fibers can be directed into multiple downstream industries, including wind equipment manufacturing, automotive production and infrastructure construction. CRRC said this capability moves blades beyond the traditional single-use model, enabling what it describes as closed-loop recovery and high-value reuse of constituent materials. The blade is described as suitable for high-capacity offshore wind turbines and designed to balance safety, environmental performance, and cost-effectiveness.

Two Years of Incremental Progress

The Sheyang production represents the latest in a sequence of recycling-focused advances CRRC has pursued since early 2025. In March of that year, the company developed what it identified as China's first TMT82 recyclable thermoset-resin blade, using an innovative resin system based on reversible chemical bonds to enable efficient depolymerization and separation of resin and fibers while retaining the mechanical performance of conventional blades. CRRC described that development as overcoming a key technical barrier to blade-material recyclability.

One month later, in April 2025, the company introduced what it called China's first mobile, high-efficiency, intelligent processing system for decommissioned blades. The system incorporates a dual-mode processing model combining distributed and centralized operations and is designed to function as a flexibly deployable smart mobile recycling factory.

Tackling the Geography of Blade Disposal

The mobile processing system is intended to address one of the most persistent practical obstacles to blade recycling at scale. Because wind installations are frequently located far from fixed recycling facilities, transporting decommissioned blades, given their considerable size and weight, has historically been both logistically complex and expensive. By deploying processing capacity directly to decommissioning sites, the mobile system aims to eliminate those transportation and disposal difficulties. CRRC said the system's processing capacity exceeds applicable national standards and described the approach as establishing a new method for large-scale recovery and reuse of thermoset wind turbine composites.

International Markets and Regulatory Alignment

CRRC has framed its recyclable blade technology explicitly in terms of international commercial ambitions. The company highlighted the blade system's alignment with the European Union's Corporate Sustainability Reporting Directive, signaling that it is positioning the product for customers in European markets where sustainability disclosure obligations are tightening. The company described the recyclable system as capable of supporting customers in meeting international sustainability objectives and reporting requirements.

The WindEnergy Hamburg announcement was made as part of a broader company presence at the event, where CRRC was simultaneously presenting its full wind power portfolio, announcing key certifications and expanding global partnerships. The completion of production at Sheyang marks the manufacturing phase of the project, with CRRC describing the outcome as providing a practical solution for managing blades at the end of their operational lives.
