The circular approach is applied along all the main phases of the life of the assets (power plants, electrical grids, etc.): from the planning (design and input material selections), implementation (management of construction site phases) and operation (maintenance oriented toward extending their useful life) up to decommissioning (management of areas, equipment, materials and infrastructures in order to identify new life cycles through reuse, upcycling, remanufacturing, recycling, etc.).
