Innovative Sustainable Approach to Reuse Dredged Sand Material to Promote Decarbonization and Circular Economy Toward Net Zero Emissions

Abstract The objective of this environmental initiative is to utilize dredged sand material for the development of artificial islands near Abu Ali Island, Eastern Province, Saudi Arabia. The aim is to reduce the environmental impact of the dredging process and create a sustainable solution for the disposal of the dredged materials. The project demonstrates a modern, sustainable and circular economy approach to target the biodiversity threats in multi-dimensional aspects and transform these threats into opportunities to improve Abu Ali Island's ecosystem. The analytical approach consists of following methodology: Identify the total quantity of sand waste generation during the dredging operation. Evaluate and identify potential waste storage facility as the laydown area on the island to temporarily store the waste. Calculate number of trucks required to transport the waste out of the area. Conduct site verification to identify potential waste disposal areas or find an alternative solution to utilize the waste material. Coordinate with corporate entities and project groups to obtain approval for proposed waste reuse solution. The reuse of dredged sand material for the development of artificial islands has several positive environmental impacts. First, it helps reduce the amount of dredged material (1.5MM m3) that needs to be disposed of in offshore locations or on landfills, which can cause harm to marine life and ecosystems. Second, it creates a new habitat for marine organisms and promotes biodiversity. In addition, it will eliminate the transportation cost (150,000 trucks) and associated traffic hazards if the material is transported outside the island. Finally, it promotes sustainable development by reducing the environmental impact of human activities on the natural environment. The implementation of this unique innovative approach at Abu Ali Island Corporate Biodiversity Area demonstrates a lead-by-example role in the environmental aspects. The corporate commitment as a global oil and gas producer toward the environment was clearly illustrated in this initiative. Building a circular environmental culture that contributes to combat climate change, sustainably falls under the company's corporate strategies. The development of artificial islands is not a new concept, but the use of dredged sand material is a sustainable and circular solution. The approach can also be proposed for the redevelopment of urban waterfront areas, where dredging is a common practice to maintain shipping channels. This environmental initiative is a win-win solution that can benefit both the environment and human development.
