General Electric鈥檚 renewables unit and LafargeHolcim, the world鈥檚 biggest cement manufacturer, have struck a deal to explore the recycling of wind turbine blades. A memorandum of understanding will see the companies focus on exploring 鈥渃ircular economy solutions.鈥� Business practices connected to the notion of a circular economy have gained traction in recent years, with many companies around the world looking to operate in a way which minimizes waste.聽In a statement, the firms added they were looking into 鈥渘ew ways of recycling wind blades, including as a construction material to build new wind farms.鈥�
The plans announced build on an already existing relationship between the two companies. Last June, GE Renewable Energy said it was going to partner with LafargeHolcim and another firm, COBOD International, to develop wind turbines that use 3D-printed concrete bases. The issue of what to do with wind turbine blades when they鈥檙e no longer needed is a headache for the industry. This is because the composite materials used in their production can be difficult to recycle, with many blades ending up as landfill when their service life ends.
As governments around the world attempt to ramp up their renewable energy capacity, the number of wind turbines on the planet only looks set to grow. This will in turn increase pressure on the sector to find sustainable solutions to the disposal of blades. Over the last few years, major players in wind energy have announced plans to try to tackle the problem.
