Shanghai's Songjiang District Unveils First Domestic 220m+ Diameter Recyclable Blade Wind Turbine

Strategic Insights -

A groundbreaking technological achievement in China's wind power industry was recently marked with the arrival and hoisting of a domestically developed 220m+ diameter recyclable blade wind turbine at Tonghua Wind Farm in Jilin. This innovation, jointly developed by Shangwei New Materials, Goldwind Science & Technology, and Sinoma Technology Wind Blade, represents a major breakthrough in green management throughout the life cycle of wind power blades. The development utilizes a recyclable resin, EzCiclo, and a degradation liquid, CleaVER, which enables the recycling of waste blades into reusable glass fibers and oligomers.

Key Takeaways:

  • The domestically developed 220m+ diameter recyclable blade wind turbine reduces the carbon footprint of each wind turbine by at least 100 tons of carbon dioxide equivalent throughout its life cycle.
  • The project uses EzCiclo, a recyclable resin independently developed by Shangwei New Materials, and a mainstream super-100-meter blade type.
  • The carbon footprint of recycled glass fibers is 56% lower than that of virgin glass fibers.
  • Goldwind Technology, Sinoma Blades, and Beijing Jianheng Certification Center Co., Ltd., in cooperation with Shangwei New Materials, have established a closed-loop system of "materials-manufacturing-certification-application".
  • The project in Liuhe County provides more than 20 million kilowatt-hours of clean electricity each year and solves the environmental problem of landfill disposal of traditional fiberglass blades.
  • The three companies have pledged to continue strengthening their cooperation and promoting the popularization and application of green technologies in the wind power industry.

Statistics:

  • 100 tons of carbon dioxide equivalent: reduction in carbon footprint of each wind turbine throughout its life cycle.
  • 56%: the carbon footprint of recycled glass fibers lower than that of virgin glass fibers.
  • 20 million kilowatt-hours: clean electricity provided per year by the project in Liuhe County.
  • 220m+: diameter of the domestically developed recyclable blade wind turbine.
