Can used wind turbine blades be recycled?

COPENHAGEN, May 17 (Reuters) – Wind turbine maker Vestas (VWS.CO) unveiled new technology on Monday which it says enables wind turbine blades to be fully recycled, avoiding the dumping of old blades. … Most blades end up in landfills, because they are hard to recycle.

Can you recycle wind turbine blades?

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.

Why turbine blades Cannot be recycled?

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.

What do they do with used wind 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. … Due to this, tens of thousands of aging blades are being removed and have nowhere to go but landfills, according to Bloomberg Green.

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.

Are wind turbine blades toxic?

While wind turbine blades are not especially toxic, the resulting landfill, if improperly handled, may contribute to dangerous environmental impacts, including the pollution of land and waterways.

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.

What is the weight of a wind turbine blade?

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.

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.

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 material are wind turbine blades made of?

Conventional blades require a lot of labor. They are a sandwich composed of fiberglass, sheets of balsa wood and a chemical called an epoxy thermoset resin. A heat oven is required to give blades the proper shape, strength, smoothness and flexibility to catch the wind and turn the turbine.

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 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.
