Waste

environmental dimension

Monitor and minimize

Reducing emissions to the environment is a public pledge and a common practice in all EDP activities.

EDP operates a waste management system that continuously strives to recover waste and reduce its production at the source.

The waste generated by EDP’s activities is collected and stored separately. It is then sent to licensed waste management operators, who carry out waste recovery processes as the preferred final disposal method.

The European Parliament and Council Directive no. 2008/98/EC introduced several changes in waste management operations, with a special focus on the definition of byproduct and the conditions underlying this classification. 

In the context of the EDP Group’s energy production activities, in 2017 the coal slag in Portugal was recognized as byproduct by the relevant authority.

The gypsum resulting from the desulfurization process is also considered a byproduct, in Portugal and Spain, as long as its physical and chemical properties comply with the existing standards. Therefore, under the legislation in force since 2011, EDP reports waste and byproducts separately.

In Brazil, although the by-product status is not applicable, theses waste materials are recovered. In 2017, the fly ash and slag has a recovery rate of 29% and 64%, respectively. 

Under the Basel Convention, EDP restricts transboundary movements of its waste. Exportation is limited to PCB waste or accidental occurrences in which the country where such waste is produced does not have the technical capacity/facilities for its removal.

According to the law, all equipment contaminated with PCB concentrations below 500 ppm must be kept until the end of its life cycle; EDP, however, is anticipating their disposal by prioritizing this kind of equipment under the company’s replacement plans.
