• SCW for wastewater treatment is China's focus. It also focuses coal water slurry

energy as minor by-product if tried ◎(Hanwha Chemical, Techno-EMI, Aquarden -
Waterox+), Also see Wet Air OxidaIon(p131)

3e Direct Combus.on(DC) of MSW: Here only MSW(Municipal Solid Waste) type
DC is discussed since other feedstock(biomass etc) is already very prevalent as

• I -Electrical Power produc.on:(Instead of burying trash into landfill), Well developed
technology to specifically handle Waste mix, many in North West Europe also
produces CHP. Some.mes cri.cized for high NOx/SOs emission, but in many G7
type level na.ons it is usually far below regula.on requirement,
• Electrical power generaIon efficiency is oUen quite low with 15-20%(eg: emission &
ash reducIon focus in Japan), sIll overall not high: 20-30+ %. Most convenIonal
large scale combusIon system(Stoker & reverse grate: Mar'n GmbH, Keppel
Seghers, Hitachi Zosen INOVA+), Also of general biomass focus,
