CRRC has completed the production of a 110m high-performance recyclable wind turbine blade at its facility in Sheyang, Jiangsu Province, China.
The newly produced blade is designed to allow more than 95% recovery of key raw materials, aiming to address the increasing challenge of blade waste as more turbines reach the end of their operational life.

It utilises a recyclable material system built around a high-efficiency, debondable infusion resin.
According to CRRC, this enables reversible chemical debonding technology, which allows for efficient separation of the resin from reinforcing fibres during processing.
The recovered resin and fibres can then be reused in applications spanning wind equipment, automotive manufacturing, infrastructure construction and other sectors requiring high-value materials.
This process is intended to support closed-loop recovery, moving away from a “single-use” model for turbine blades.
Industry data referenced by CRRC indicates that demand for decommissioning and disposal of wind turbines in China is rising.
Forecasts suggest that more than 470GW of additional onshore and offshore wind installations are expected nationally in the coming years.
By 2030, estimates point to the retirement of more than 30,000 wind turbines, representing 44.73GW in capacity and resulting in approximately 947,900t of related solid waste.
CRRC noted that the new recyclable blade system can assist customers in meeting various international sustainability and reporting requirements, including the EU’s Corporate Sustainability Reporting Directive.
The new blades are suitable for high-capacity offshore applications and combine safety, environmental attributes and cost performance.
In addition to the 110m blade achievement, CRRC reported further efforts to develop circular technologies for the wind sector.
In March 2025, the company developed the TMT82 recyclable thermoset-resin blade, which also uses a resin system based on reversible chemical bonds, supporting efficient material separation while maintaining mechanical properties.
It also introduced a mobile, high-efficiency processing system for decommissioned wind turbine blades in April 2025.
