EfW world overview
Global future waste outlook The Worldwide Need for Safe Waste Management is Enormous!!! World population 7 bn ;growth @ 1.3%. Total MSW generated ~ 1.3 bn MT/y 26 megacities 410 cities with population > 1 million 11
Global future waste outlook 2'500 Development of MSW (mtpy) Need for Thermal Treatment (mtpy) 2'000 1'500 +69% Maximum Potential for recycling 50% Need for New Thermal Processing Capacity of Residual MSW by 2025 over 870 mtpy 1'000 +91% 2'200 500 1'300 1'102 876 680 0 2002 2012 2025 Residual MSW volume suitable for thermal treatment (Min.) 226 Existing EfW capacity Need for thermal treatment By 2025 > 870 T/y Capacity for Thermal Treatment of Residual MSW will be Needed in Addition to Existing 226 T/y 12 Source: World Bank
EfW Technology requirements High flexibility to treat a wide range of waste Power plants with high reliability High efficiency with combined heat and power (CHP) Low environmental impact CAPEX to be reasonable High efficiency and fuel flexible Energyfrom-Waste solutions from Valmet Govt. policy to exist and encourage EfW is Well Established Option (> 2000 plants across world) to treat Residual Waste 13
Valmet fluidized bed combustion for EfW
Fuel from residual waste Pretreatment Single stage shredding Removal metals Separation stones, glass 15
Valmet solutions part of an integrated concept Sorting Heat and electricity Maximizing energy business Residual waste Pretreatment in MRF or MBT Maximizing recycling business Industrial Recyclates waste Refuse derived fuel Wet waste RDF Power plant - highest energy efficiency Multifuel capability sludge, biowaste, biomass, agro, coal Biodrying or AD MBT Mech.

Valmet CFB for EfW Strong track record More than 70 units in operation, with 7 for EfW Superior fuel flexibility RDF, biomass, agro, sludges and coal all in one boiler Proven high reliability Higher than 99% High boiler efficiency 91-92% ɳ > 28% High steam parameters 75 bar / 520 ºC Excellent environmental performance Low NOx and almost zero UBC (Unburn Carbon) in ash Relatively low maintenance cost No moving parts in furnace 19
Valmet CFB for Refuse Derived Fuel (RDF) Special design features Empty pass with Water soot blowing Replaceable super heaters Refractory covered furnace Reliable fuel feeding equipment Flue gas cooling down <620 C Effective removal of bottom ash, sieving & recycling Final superheater in loop seal, outside fluegases 20
Challenge: High temp corrosion due to Chlorine (Cl) in RDF Solution: Loop seal superheater Final superheater in loop seal is effectively isolated from fluegases Gas atmosphere much less corrosive compared to furnace or back pass Double layer tube design for RDF application to avoid alkali chlorine condensation Allows steam temperature up to 520 ºC with limited corrosion risk Outside surface T ~ 700 C Inside T = 450..520 C 21
