Waste management overview

ExxonMobil devotes a great deal of attention and expertise to controlling waste, ground contamination and nuisance.


Waste management overview

For many years, the waste water from the refineries and chemical plants has been thoroughly cleaned in special installations. These are comprised of multiple units, including oil separators, equalizer basins, flocculation and flotation units, a biological stage and resettling ponds. But even more important are the considerable efforts to minimize water contamination at its source, including the reuse of the wastewater flow as process water. This avoids putting any unnecessary burden on the water treatment plants.

Solid waste is also a major focus of attention. The primary goal is to minimize its production, followed by maximizing the separation and, if possible, reuse of the waste flows.

ExxonMobil Chemical employs a double strategy with respect to ground contamination. On the one hand, ground contamination projects are used to tackle past ground contamination and, on the other hand, major efforts are being made to prevent any new contamination.

ExxonMobil dares to state that under normal conditions its plants do not cause any noise or odor nuisance. The design and procedures focus on preventing incidents, and therefore complaints. Environmental management by company employees and contractors is high on the list of priorities. Within this framework, employees are encouraged to systematically report near misses - as they are in the safety policy - to enable lessons to be learnt from past mistakes. Consequently, there are relatively few incidents.
