Can turbine blades be recycled?

Wind turbines generate electricity without using fossil fuels or producing particulate matter pollution, but they do create waste: Though they can last as long as 25 years, turbine blades cannot be recycled, piling up in landfills at the end of their life.

How do they dispose of windmill blades?

When wind turbine blades reach the end of their usefulness, most are sawed into transportable pieces and hauled to landfills, where they never break down. Because of the resources and energy that go into producing these blades, this type of disposal is inefficient and wasteful.

How long does it take for wind turbine blades to decompose?

Although most wind turbine blades can be used for up to 20-25 years, most blades are taken down after 10 so that they can be replaced with larger and more powerful designs.

Why can’t they recycle wind turbine blades?

Wind turbine blades are mostly made with fiberglass or carbon fiber heated together with resin to combine into a material that is light and yet still strong enough to withstand intense storms. Consequently, it’s difficult to recycle. At the end of their working life, most blades are buried underground or burned.

Why can wind turbine blades not be recycled?

Turbine blades are made by heating a mix of glass or carbon fibres and sticky epoxy resin, which combines the materials, providing a strong light-weight composite material, but which also make it hard to separate the original materials for recycling.

Who recycles wind turbine blades?

Carbon Rivers, based in Tennessee, U.S., recycles scrap composites, including wind turbine blades, and extracts the glass fiber in a discontinuous form using pyrolysis.

How toxic are wind turbines?

There is no problem with the fiberglass, but with the composite materials added to make the wind turbine blades. These composite materials often contain toxic plastics that are hazardous to the environment. Some of these plastics have Bisphenol A, a very hazardous chemical.

What is the lifespan of a wind turbine blade?

Wind turbine blades last an average of about 25 to 30 years. When they are replaced, the old blades become a challenge, from transporting them out of the field to finding a place to store the blades, which can be longer than a Boeing 747 wing.

Are wind turbines bad for the environment?

As with all energy supply options, wind energy can have adverse environmental impacts, including the potential to reduce, fragment, or degrade habitat for wildlife, fish, and plants. Furthermore, spinning turbine blades can pose a threat to flying wildlife like birds and bats.

How much oil is in a wind turbine?

Check the Oil

Gearboxes on the generally smaller-sized turbines installed in the mid-1980s hold about 10 gallons of oil or less. Newer, larger machines might hold as much as 60 gallons.

What happens to wind turbines when they are decommissioned?

Once blades are decommissioned, they could be reused, disposed of, or the materials could be recovered. Momentum is building among the top wind developers to find easier ways to achieve that third option: material recovery. Last week, Orsted announced it would “reuse, recycle or recover” all of its blades worldwide.
