Some of the figures below only apply to BP whereas other figures take the whole of the site into account. That is the case for 'waste water slurry’ and ‘calcium slurry’.
These are the absolute quantities of solid waste removal in tonnes per year.
The term 'dangerous industrial waste' is explicitly defined in Belgian legislation. It all adds up to the fact that all products or substances marked with a warning label (orange label) are specified as 'dangerous'. Products exposed to oil are dangerous waste.
