US: Veolia North America (VNA) has signed a contract for the supply of used blades from onshore wind turbines from GE Renewables. The waste management company will process the blades to produce shredded composite materials for use in cement production, both as replacement for war materials such as sand and clay and as an alternative fuel. As a part of the agreement, blades that have been removed from turbines will be shredded at VNA’s processing facility in Missouri and then used in cement plants across the US. On average, nearly 90% of the blade material, by weight, will be reused as a repurposed engineered material for cement production.
Environmental solutions and services chief operating officer (COO) Bob Cappadona said, "By adding wind turbine blades — which are primarily made of fibreglass — to replace raw materials for cement manufacturing, we are reducing the amount of coal, sand and minerals that are needed to produce the cement.” GE Renewables and sustainability consultant Quantis said that the use of turbine blades in cement production would reduce net CO2 emissions by up to 27% and water consumption by up to 13%.
