Best answer: 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. This is a process where material is heated to very high temperatures in the absence of oxygen in order to thermally decompose chemical compounds.

Is anyone recycling wind turbine blades?

Siemens Gamesa calls its RecyclableBlade “the world’s first wind turbine blade that can be recycled at the end of its lifecycle,” and a “milestone” for the wind industry. But other companies are also working to keep turbine blades from filling landfills.

Where are wind turbine blades disposed of?

In the United States, it is estimated that up to 8,000 wind turbine blades will be removed and sent to landfills in Lake Mills, Iowa, Sioux Falls, South Dakota, Casper, Wyoming, and several others.

How do they dispose of turbine 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.

Why can’t they recycle wind turbine blades?

Unfortunately, thermoset plastics are almost impossible to recycle, so the blades do not have much scrap value and are not very appealing to recyclers. Therefore, many spent turbine blades are piling up in landfills, although some reinforced plastic blades are downcycled into cement products.

Where are wind turbine blades made in USA?

Siemens Power Generation announced August 17 that it has selected Fort Madison , Iowa , for its U.S. wind turbine blade manufacturing site.

Are wind turbine blades biodegradable?

And, to make matters worse, not all landfills accept wind turbine blades for dumping. So, the few that accept only have the blades piling up in their landfills because they take extremely long years to biodegrade, and there is not much use you can put them to.

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.

Why do wind turbine blades have to be replaced?

They need to transfer large forces from gale-force winds on the blades, and they are challenging to keep clean and to maintain them since they are located about 100 metres up in the sky. Furthermore, they are laborious to replace.

How much does a single wind turbine blade cost?

For a 1.5-MW turbine, typical blades should measure 110 ft to 124 ft (34m to 38m) in length, weigh 11,500 lb/5,216 kg and cost roughly $100,000 to $125,000 each. Rated at 3.0 MW, a turbine’s blades are about 155 ft/47m in length, weigh about 27,000 lb/12,474 kg and are valued at roughly $250,000 to $300,000 each.

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.
