During the pandemic to keep the project going.Reuse wind turbine blades can old wind turbine blades be reused for a 'second wind'? When wind turbine blades reach the end of their usefulness, most are cut into transportable pieces and taken to landfills, where they are never broken down. Due to the resources and energy used to produce these sheets, this type of disposal is inefficient and wasteful. Recently, several innovative companies have begun brainstorming better ways to reuse this green technology once it goes offline. Wind turbines are built to last an industry standard 30 years. As installed wind energy capacity continues to increase globally, it is increasingly important to think about the next phase of a wind turbine's life cycle: the end. Some existing turbines have already been taken out of service and decommissioned at the end of their life cycle, or during "Repowering", a process in which companies replace smaller turbines with larger ones capable of producing more energy. Wind turbine blades can be reused, however, older blades are more difficult to recover.
Why? While approximately 85% of turbine component materials, including steel, copper gauge, electronics and gears, can be recycled or reused, old blades are more difficult to recover. Because the blades are composed of fiberglass, a lightweight and durable composite material ideal for weathering storms, separating the plastic and glass fibers for recycling is difficult, the article found. The process also requires powerful, diamond-encrusted indus Phone Number Data trial saws and a lot of effort. Because of this, tens of thousands of old blades are being retired and have nowhere to go but landfills. Reuse wind turbine blades reusing wind turbine blades are the solution to the waste crisis. Scientists around the world are focused on finding ways to recycle, recycle and redesign shovels for the future. Washington-based global fiberglass solutions (gfs) believes it is the first us-based company to reuse fiberglass wind turbine blades commercially, according to a plastics recycling update report 2019. According to a press release, the company grinds discarded leaves, which are then used for decking materials, pallets and pipes.
Wind energy giant ge similarly announced a wind turbine blade recycling program in the us, in which most old onshore turbine blades would be shredded and used to replace raw materials. In cement manufacturing, they reported at the end of last year. The process should make wind turbines completely recyclable while reducing carbon dioxide emissions from cement production by a net 27%. Since concrete is the most widely used man-made material in existence, the production of cement, one of its composite materials, accounts for about 8% of global carbon dioxide emissions, the bbc reported in 2018. Veolia , the company that will process the wind blades for recycling, hopes to use this co-processing technology to create a greener cement, said bob cappadona, executive vice president of environmental solutions and services for veolia north america. “last summer we completed a trial with a ge blade and were very happy with the results. This fall we have processed over 100 sheets so far and our customers are very satisfied with the product,” cappadona said. Recycling could be a stronger solution for the planet because the strength and durability of old blades is not wasted by shredding them.
