Hg air emissions in Hazardous Waste Incinerators 10 years for a global understanding Monitoring and Treatment of Hg air emissions 21/09/2018 5
Contribution of the Waste Incineration sector to the total emissions to air (2012) Countries taken into account covered 69% of the EU inhabitants Waste Incineration Sector Contribution is about 7,5 % Monitoring and Treatment of Hg air emissions 6
How to reduce the contribution of incineration? Better monitoring (EU target, continuous) Adapted and dedicated treatment in order to reach lower levels (EU target, 5-20 µg/Nm 3 ) Monitoring and Treatment of Hg air emissions 7 21/09/2018

Costs? Very low compared to the benefit for health and the environment! Monitoring and Treatment of Hg air emissions 14
Monitoring & Treatment in dedicated HWI Depends on the monitoring equipments and the reagents chosen 0,2 to 0,31 €/t with a wet flue gas cleaning system (approx. double with a dry flue gas cleaning system) The 14 lines for hazardous waste incineration of SARPI in Europe are fully equipped (monitoring and treatment) Monitoring and Treatment of Hg air emissions 15
Challenges... Monitoring and Treatment of Hg air emissions 16
Risks of re-emission of mercury ● Avoid recirculation in the scrubbers ● Emission from SCR during regeneration if placed at the end of the FGC system Monitoring and Treatment of Hg air emissions 17
