New generation in Waste incineration Historical waste incineration “generations”: l 0Open air incineration l 1 st 1900 oven l 2 nd 1960 dust removal from flue gas l 3 rd 1985 chemical cleaning of flue gas In this presentation we outline a new step: l 4 th 2006 recovery of energy and materials Historical waste incineration “generations”: l 0Open air incineration l 1 st 1900 oven l 2 nd 1960 dust removal from flue gas l 3 rd 1985 chemical cleaning of flue gas In this presentation we outline a new step: l 4 th 2006 recovery of energy and materials

25 Gemeente Amsterdam Afval Energie Bedrijf Why new generation ? Historical development of public awareness: newly identified needs lead to a new technical concept. So now recovery is the “next logical step”. Historical development of public awareness: newly identified needs lead to a new technical concept. So now recovery is the “next logical step”.

26 Gemeente Amsterdam Afval Energie Bedrijf Energy-potential in Waste Waste in EU : 182 MTon/year x 10 MJ/kg x 30% Electricity:= 550 PJ / year = 150 TWh / year = MW-continuous = 8 % of total EU-production Avoided CO 2 = 60 million Tons per year Waste in EU : 182 MTon/year x 10 MJ/kg x 30% Electricity:= 550 PJ / year = 150 TWh / year = MW-continuous = 8 % of total EU-production Avoided CO 2 = 60 million Tons per year

CONCLUSION COST, can/must go DOWN SIMPLE process, do it OPTIMAL Environmental efficiency, use al SYNERGY Efficiency > 30% instead of 22% COST, can/must go DOWN SIMPLE process, do it OPTIMAL Environmental efficiency, use al SYNERGY Efficiency > 30% instead of 22%

34 Gemeente Amsterdam Afval Energie Bedrijf Recovery is the new Rule It was WI: Waste incineration It is WTE: Waste To Energy It will be WFPP: Waste Fired Power Plant When efficiency greater than 30% It was WI: Waste incineration It is WTE: Waste To Energy It will be WFPP: Waste Fired Power Plant When efficiency greater than 30%
