Zusammenfassung:

• Tire pyrolysis is an option for recycling• Plant in Hirohata in operation since 2004 with a 60.000 t/a capacity

• IED: Co-Incineration plant• Flue gas has to be treated accordingly (i.e. 17. BImSchV in Germany)

• Economics of plants strongly dependet from Crude Oil price level• Currently not economical

24

Gasification of Waste

Direct Melting System

• Gasification process for untreated MSW• Developed in Japan; plants in Japan and Korea• More than 40 years of experience; first plant in operation in 1974

• Treatment of:• MSW without pre treatment• Clinical waste• Sewage sludge• Hazardous waste• Material from landfill site reclaiming activities

• Very high slag quality

Reliability - Measures for Scaling-up of Gasifier -

31

Scale-up of gasification technology is one of the technical issues.- Gasification reaction in the gasifier.- optimization of waste charging and combustion conditions.

Our gasification (Direct Melting System) gradually expanded its capacity, during 38 years and reach now a capacity of 14 t/h per line (330 t/d).
