About How to remove the blades of a large wind turbine
Ninety percent of a turbine's parts can be recycled or sold, according to Van Vleet, but the blades, made of a tough but pliable mix of resin and fiberglass — similar to what spaceship parts.

The time to disassemble, demolish, and remove wind turbine components (see Figure 12) and wind energy project-related infrastructure and conduct restoration activities can be 6–24 months, depending on the size of the turbines and the number of turbines involved in the project.
Most of the concrete foundations used to anchor the wind turbines, however, are as deep as 15 feet. The concrete bases are hard to fully remove, and the rotor blades contain glass and carbon fibers that give off dust and toxic gases.
creating a circular economy for wind turbines — future blades should be designed so that they are easy to repair and refurbish. However, it is important to note that refurbishing existing blades on a full re-power of an existing wind asset may.
Abstract. Currently, up to 94% of a wind turbine can be recycled.1. However, the rotor blades are made of composite materials (e.g., Fiber-Reinforced Plastics, mostly fiberglass and carbon fiber) and pose a more significant recycling challenge to the wind industry and the composite materials sector. As Fiber-Reinforced Plastics (FRPs) are .

6 FAQs about [How to remove the blades of a large wind turbine]
How can wind turbine blades be cut?
Different technologies may be used for cutting. The GenVind project (2012–2016) investigated several techniques, which were reviewed and described by Jensen and Skelton . They list wire saw, circular saw and water jet cutting. The materials obtained from end-of-life wind turbine blades may be found in a shape close to the original ones.
How are wind turbine blades recycled?
At the Veolia North America facility, large saws cut the wind turbine blades into smaller sections as part of the recycling process. Cutting and shredding convert huge wind turbine blades to hand-sized chunks. Veolia North America ships this material to customers that blend it with raw materials to make cement.
What is wind turbine blade waste?
By 2050, it is projected that wind turbine blade waste could range from about 200,000 to 370,000 tons per year, depending on operational lifetime of these components (15–25 years). Even at this level, blade waste would be equivalent to less than 0.15% of combined municipal solid waste and construction and demolition waste from 2018.
Are wind turbine blades hazardous waste?
Wind turbine blades are labelled as non hazardous waste. The waste is also allocated a six digit number according to how the waste was produced. For waste made of multiple materials such as glass fibre polymer composite, this is challenging.
Why are wind turbine blades difficult to re-process?
Due to the nature of the materials used in wind turbine blades, namely glass fibre reinforced thermoset polymer composite, wind turbine blades are technically difficult to re-process and convert into new valuable materials.
Should wind turbine blades be buried?
Now, just 2 years later, Veolia runs a program that has already turned about 2,000 of the giant blades into a valuable commodity—cement. When wind turbine blades reach the end of their 20-to-25-year service lives, they usually end up in landfills. But in the past several years, energy companies have sought ways to avoid burying retired blades.
