Grup Heracles companies engage in the collection, transport and final disposal of dry sludge, and banal and sifted waste generated at wastewater treatment plants (WWTPs).
Dry sludge and banal waste are transported to the Andorran treatment plant, where these materials are used to generate energy. In the case of waste that cannot be used to generate energy, such as sifted waste and sand, this is transported to landfill sites.
