SlagsAbout 200 kg of slag are produced per ton of incinerated MSW.
The slags are sent to the Bottom Ashes Treatment and Recovery Facility (ITVE) in the Sanitary Landfill of Mato da Cruz and, after adequate maturation, can be used as inert for the civil construction, public works and eventual landscaping recovery.
Ashes and wastes from gas treatmentAbout 30 kg are produced per ton of incinerated MSW.
