Repsol YPF

Waste management

Considering the diversity of the company’s activities, the specific legislation applicable and the existing geographic locations, Repsol YPF is strongly committed to a correct waste management programme, applying consistent standards in all places in which it operates.

In order to ensure correct management of waste throughout the entire company there is a corporate waste management regulation which applies to all of the countries where Repsol YPF operates.

Among the main kinds of waste generated by Repsol YPF’s operations, there are slurries from the cleaning of the bottom of the tanks, drilling slurries, earthworks for construction or modification of installations and finally, hydrocarbon contaminated soils, maninly because of soil remediation of spills.

The hazardous waste that was managed in 2007 was similar to the 2006 data.

During 2007, there was a rise in the extraordinary hazardous waste (approximately 15%), resulting from the works undertaken at the Petronor refinery to construct a fuel reduction unit (FRU) and from management of land following the drainage of an old waste tank at the Puertollano chemical plant. The increase is partially offset by the reduction in land polluted by hydrocarbons managed in exploration and production activities.

Non-hazardous waste is up by 2% compared to 2006, mainly due to the growth in exploration activities in Libya and Peru. This rise is partly offset by the decrease in waste managed at the La Pampilla refinery (Peru), where in 2006 large quantities of non-hazardous waste were treated due to the waterproofing of basins and construction of new tanks. These projects continued in 2007 but generated less waste.

In terms of management, 53% of hazardous waste and 21% of non-hazardous waste were earmarked for reuse, recovery or recycling. External management has increased, due to the growth in extraordinary waste generated from construction works and floor drainage in refining and chemical activities in Spain.
