Discharges and treatment
Treating hotel effluent
The environmental footprint study looked at the impact that Accor
hotels may have on groundwater eutrophication (the deterioration
of an aquatic system due to over-enrichment by nutrients like
phosphorous or nitrogen). It estimated that Accor-generated
eutrophication stands at around 3,180 tonnes of phosphates per
year. The two main sources of this type of impact are runoff from
the fertilizers and pesticides used by the farmers who grow Accor
foodstuffs, which accounts for 94% of the total, and the organic,
chemical and other matter released in hotel wastewater.
Accor is able to act directly on the second source, based on the
principle that all hotel wastewater effluent should be systematically
treated in an appropriate treatment plant, either on-site or in the
local community. According to data reported
via
the MACH hotel
asset management application:
ƒƒ
86 hotels have an on-site treatment plant and 65 use the treated
water for grounds watering;
ƒƒ
42 hotels have rainwater cisterns for grounds watering;
ƒƒ
111 hotels usewater fromdedicated networks for groundswatering.
