Solutions
We propose repurposing decommissioned wind turbine blades (DWTBs), currently treated as waste, to create durable and sustainable coastal and public structures. This approach leverages the durability and anti-corrosion properties of the turbine blades, extending their lifecycle by 30 to 50 years under static load conditions with occasional dynamic loads, even after their dynamic fatigue life has been exhausted. These solutions leverage the anti-corrosion properties of wind turbine blades, extending their lifecycle and helping to reduce environmental waste and CO2 emissions. Below are some examples of how DWTBs can be repurposed:
 These blades can be repurposed as structural columns for elevated houses in coastal regions. Their durability and anti-corrosion properties make them ideal for areas exposed to saltwater and extreme weather, ensuring long-lasting structural integrity. |

Using DWTBs as sea walls provides a sustainable barrier against rising sea levels and strong waves. Their unique structure allows them to withstand the harsh marine environment, offering a cost-effective and eco-friendly solution for coastal protection.
Repurposing the root section of decommissioned wind turbine blades into pipe culverts for drainage systems helps to manage the blade waste as well leverages on the high mechanical properties of the blade material. These culverts can be incorporated into roadways or stormwater systems, improving water management and reducing flooding risks.
DWTBs can serve as coastal columns in various marine infrastructure, such as piers and jetties, providing excellent resistance to saltwater corrosion and strong wave impacts, significantly improving the durability of coastal installations. Also the hydrodynamic shape of the blades can significantly improve the flow conditions and reduce erosion.
In port areas, DWTBs can be utilized as fenders and girder barriers, offering robust protection against vessel impacts while resisting wear and tear in a challenging saltwater environment.
Repurposed turbine blades can also be used in the construction of recreational piers, providing an environmentally friendly alternative to traditional construction materials. These piers would be durable and resistant to corrosion, ensuring long-term usability for coastal communities.
In public parks, DWTBs can be transformed into swings, combining functionality with sustainability. These swings are not only durable but also add an element of eco-conscious design to community spaces.
Repurposed turbine blades can be turned into swings in public parks, combining fun and sustainability. These swings not only offer a unique design but also showcase how discarded materials can be given a second life in community spaces.
DWTBs can be transformed into artistic sculptures that blend aesthetics with sustainability. These sculptures can be placed in parks, along walkways, or as part of urban installations to inspire conversations about renewable energy and environmental responsibility.
A solar canopy made from DWTBs incorporates solar panels on top, creating a dual-purpose structure. It provides shade and seating while generating clean energy, demonstrating a comprehensive approach to sustainability in public spaces.
A pedestrian bridge constructed from DWTBs offers a lightweight, corrosion-resistant structure, making it ideal for areas prone to harsh weather. This bridge serves as both a functional crossing and a statement about the potential of upcycled materials in infrastructure.
