We are focusing our efforts on proper waste management, so that we can mit- igate the impact it may have on the en- vironment. The waste we generate is de- livered to authorised waste managers for proper environmental treatment, with pri- ority going to those who reuse this waste either through recycling or to generate en- ergy. Moreover, in the case of waste that has to be exported to be properly treated, we carefully control how it is transported and converted for another use.
During the year, only 1% of all hazardous waste generated was transported.
Lastly, we specifically manage drilling waste produced during Exploration and Production unit operations depending on the water content thereof. How it is treat- ed and where it is sent varies according to its characteristics to ensure it is proper- ly processed.
