Wind-Turbine Blades Once Doomed for Landfill Can Now Be Recycled Back to video Turbine blades can be bigger than the wing of a Boeing 747, and many of them end … Wind turbine blades present a unique materials recovery challenges, a point emphasized by Veolia, a global utilities and waste management company working to develop recycling solutions for them. To avoid hazardous dust, GFSI uses wet wire blades that are thin and strong enough to slice open each wind blade. With some as long as a football field, big rigs can only carry one at a time, making transportation costs prohibitive for long-distance hauls. A wind turbine’s blades can be longer than a Boeing 747 wing, so at the end of their lifespan they can’t just be hauled away. In the future, you add a chemical substance that can separate the glass from the plastic fibers so they can be recycled. Daniel Laird, a U.S. Department of Energy researcher, says most of a turbine can be recycled, including "a lot of metal — steel and copper." A new material for wind blades that can be recycled could transform the wind industry, rendering renewable energy more sustainable than ever before while lowering costs in the process. Thermoplastic materials have a higher resistance to abrasion and fatigue (higher toughness) than most thermoset materials [8] . Wind turbine blades are piled up outside a former Maytag plant in central Iowa where a company hopes to help recycle them into a wide range of products. Bob Cappadona, COO for VNA’s Environmental Solutions and Services division, said "By adding wind turbine blades — which are primarily made of fiberglass – to replace raw materials for cement manufacturing, we are reducing the amount of coal, sand and minerals that are needed to produce the cement, ultimately resulting in greener cement that can be used for a variety of products. First, you need to saw through the lissome fiberglass using a diamond-encrusted industrial saw to create three pieces small enough to be strapped to a tractor-trailer. Recycled wind turbine blades can help clean up cement production – but how? GE Renewable Energy says ground-up turbine blades could replace raw materials such as … Wind power is carbon-free and about 85% of turbine components, including steel, copper wire, electronics and gearing can be recycled or reused. Wind-Turbine Blades Once Doomed for Landfill Can Now Be Recycled (Bloomberg) -- Veolia Environnement SA agreed to recycle General Electric Co. wind-turbine blades into a raw material that can … Global Fiberglass Solutions, based in Washington state, has devised a way to slice up retired wind turbine blades into tiny pellets that can then be molded into products such as boards, furniture and packaging. A wind turbine’s blades can be longer than a Boeing 747 wing, so at the end of their lifespan they can’t just be hauled away. But the fiberglass blades remain difficult to dispose of. Facebook. Local media reports several wind farms in the state are sending over 900 un-reusable blades to the Casper Regional Landfill to be buried. (Article by Adan Salazar republished from Infowars.com). The wind blades can be broken down by the grinding equipment on location, so there is no need to ship entire blades to a recycling point. As the report explains, GFSI’s recycling process begins at a wind farm, where technicians cut blades into 18.5-meter chunks. 1.1.1 General Recyclability To understand the need to focus on recyclability of the wind blades, a general knowledge of current wind turbine recycling is needed. A wind turbine’s blades can be longer than a Boeing 747 wing, so at the end of their lifespan they can’t just be hauled away. By using GFSI’s recycling process, GE could reuse 50 million pounds of waste in the next couple of years. Danish Researchers Developing Solvent to Recycle Fiberglass Wind Turbine Blades. Though the blades make up only about 10% of a wind turbine’s total material, they are often made with fiberglass and can’t be recycled or easily repurposed. An example of a thermoplastic material, which can be used in the production of wind turbine blades, is called PA-6 (this material is currently being researched by Delft University). Researchers demonstrated the feasibility of thermoplastic resin by manufacturing a… The recycling of these old blades is a top priority for the wind industry which is committed to the principles of a circular economy.
