Utilization of waste wind turbine blade in building materials
Wind power has become a cornerstone of modern energy systems.Upon retirement of wind turbine generator,the recycling of discarded wind turbine blades(WTBs)presents a challenge due to their difficulties in crushing and decomposing.It is necessary to explore a sustainable pathway to recycling waste WTBs within the realm of green economy.For the dominated materials of fiber reinforced polymer(FRP)in wind turbine blades,this review summarized the strategies and primary methods for the utilization of waste WTBs,and introduced briefly the advantages and disadvantages on mechanical,thermal and chemical methods.Due to the low values of the components in the waste WTBs,the existing recycling methods were lack of a substantial economic benefits without government subsidies or disposal costs from the waste-producing firms.Therefore,the mechanical methods with a simple process recycling the waste WTBs for construction materials reinforcement should have a promising economic benefit and application prospect.This review summarized the research progress of FRP materials from waste WTBs being used as the reinforcing agent in concrete,cement mortar and geopolymer.The FRP materials from waste WTBs can provide construction materials excellent tensile and flexural stress even after fracture.However,there were issues with the inadequate bonding strength between the FRP material and cement,and the FRP material reduced the density of construction materials,potentially leading to a decrease in compressive strength.Further research should focus on improving the bonding strength between FRP materials and cement,and optimizing size of FRP materials and its blending ratio to enhance the overall performance of construction materials.In general,the blending ratio of FRP materials should be kept in a suitable and low level to ensure the strength of construction materials.The huge amount of construction materials,such as concrete and cement mortar,can consume the waste WTBs even with a very low blending ratio.
