How to cut wind turbine blades

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.

Where do wind turbine blades usually end up?

Because there are so few options for recycling wind turbine blades currently, most of those that reach end-of-use are either being stored in various places or taken to landfills. (Bloomberg Green reported earlier this year on wind turbine blades being disposed of in landfills.)

Can wind turbine blades be recycled?

A three-year project providing the basis for commercialization of sustainable recycling of wind turbine blades. Read more about the recycling technologies here. Establish functional, sustainable value chains to handle end of life wind turbine blades from decommissioning, to re-processing and recycling in new applications.

How are wind turbine blades made?

Wind turbine blades are built from multilayered laminates, made from glass or carbon fibers, and thermoset polymer matrix, joined by adhesive layers, and partally filled with foams. The mechanical disintegration of wind turbine blades into smaller parts (realized as cutting, shredding, crushing, milling) is a step of almost every recycling process.

How do I make my wind turbine blade look good?

Finally, sand the blade, and it will look great! Since Pine is a soft wood, it is susceptible to being nicked. I suggest you apply a few coats of wood hardener. Its cheap, and will make your wind turbine blade more durable. Then paint it. Don't get the cheap spray paint, it will take you 3 coats for it to even look good.

Are there alternatives to waste turbine blades?

Instead of landfilling wind turbine blades, some alternatives are being developed. For instance, two large utilities in the US, PacificCorp and MidAmerican Energy, have recently announced plans to partner with the Tennessee company Carbon Rivers to recycle their spent turbine blades.
