Wastes

The wastes generated by EDPR are not directly linked to the generation process. Most of them are related to turbines’ operation & maintenance process and the rest are wastes originated in facilities and offices.

More than 90% of the hazardous waste produced by wind farms is related to oil and oil-related wastes such as oil filters or oil containers, used mainly for lubrication of the turbines. The consumption of this oil is based on certain pre-defined replacement time frequencies (between 2 and 5 years, based on the component, oil type and manufacturer).

Wind farms are equipped with different bins for non-hazardous waste segregation. Hazardous waste is packed, labeled and stored until final treatment is given by an authorized waste handler. The company promotes the recovery of waste rather than disposal through recycling and other means. EDPR has been actively working to improve the recycling rate of its hazardous wastes, through authorized waste haulers.

Annual fluctuations in hazardous waste generated are heavily dependent on the pluri-annual oil replacement programs above mentioned. Non-hazardous wastes generated by the company include metals, plastics, paper or domestic garbage which is recycled in their vast majority.
