As an example of the supplier engagement programme development, we initiated a collaboration with wind turbine manufacturer Siemens Gamesa to use recycled glass fibres for certain new wind turbine blades at our Greater Changhua 2b and 4 offshore wind farms in Taiwan. The intended outcome of our supplier engagement and procurement strategy is to have a firm set of circularity-related supplier requirements in place within the next four to five years. For selected components, recycled materials have already been introduced as a sourcing evaluation criterion, ensuring our gradual transition away from the use of virgin resources.

Waste is generally reported on the basis of invoices received from waste recipients, supplemented with plant-specific measurement methods for commercial facilities, including construction activities. Part of the oil-contaminated wastewater from the North Sea oil pipeline has been treated as waste and therefore reported as waste and not wastewater. Residual products, e.g., gypsum from the CHP plants, which are not handled as waste but sold as products, are not included. Soil from excavation projects is not included.
