3 Major Features Emissions Air < 20% EU maximum limits Soil < 1% landfill, potentially zero Water Zero Odor None, facility under negative pressure Noise < fence. High public acceptance No protest against expansion MSW transportation includes rail and water Attractive architecture Efficiency Electricity > 30% net efficiency. District Heating 3-5%, potentially 30%. Material recycling > 99%, metals, building products, gypsum, salt. 3

4 Major Features (cont d) Availability 94% Capacity 1.5 million tons, world s largest single facility Best Available Technologies applications avoid environmental obsolescence, extends economic plant life Tipping fees of 60 are the lowest in The Netherlands, because of optimum CAPEX-OPEX balance, availability, capacity and BAT. Robust design permits debottlenecking option 10 to 20% Integration with Municipal Waste Water Facility maximizes economics and creates zero waste MWWF operation. AEB Experience covers 85 years in planning, design, building & operation, resulting in many innovations and patents. 4

15 Waste Fired Power Plant WFPP in a nutshell Clean emissions Waste Waste Fired Power Plant Energy = Electricity & Heat >30% net electrical efficiency 100% renewable energy 50% sustainable (CO2-free) energy (endless stream; 50% biomass) Valuable Materials Sand & granulate for construction (Non)-ferrous metals Industrial salt, gypsum. Residues (<0.5%) 15

16 Emission levels Emissions WFPP vs Dutch limits 100% 80% 60% 40% WFPP as % Legal limit Dutch limit 20% 0% NOx NH3 C tot.org. HCl HF SOx CO PM Hg Cd, Th HM PCDD/F 16

17 Energy from WFPP Electrical Efficiency of Power Plants Depends on fuel quality: Natural Gas 55 % Oil 50 % Coal 45 % Lignite 40 % Biomass 35 % Waste 30% 15% 22% Current: New: Waste Average state-of-the-art Fired Power Plant Energy with net avoidance of CO2!! 17

18 From Residues to Products How to capture the value? Bottom-ash: mining technologies Joint R&D with TU Delft Wet separation process (patented) Economically profitable (metal recovery) Avoiding large volume of CO2 18
