6 Key factors for Waste Gasification in UK Market Situation Developing several gasification projects Some failures of gasification suppliers Key Factors (1) Technical Reliability Should have commercial plants, not demonstration plants (References) Well proven (Capacity, Operating conditions) Should know WASTE Operating Know-how (2) Company Reliability Should have strong financial condition EPC Capability Single responsibility => Bankable technology 6

7 Formation for waste Gasification in UK EPC Capability in the UK based on EFW Projects After Sales Service for EFW and Gasification Adjusting gasification technology to European and UK market Technology Provider of Proven Waste gasification - 47 references - 38 years experiences (since 1979) - Various kinds of waste processing references Operation support / Training R&D activities for waste gasification As NSENGI Group, we can offer reliable and bankable scheme for waste gasification in the UK. 7

8 Waste Flexibility Mainly MSW or RDF with other waste This system has high waste flexibility and requires no pre-treatment. No pre-treatment High temperature gasification (>1,800 C) Double damper system (max. 800 mm) Syngas Waste Flexibility - additional value for waste receiving Sewage sludge Bottom ash Landfill Waste Clinical Waste High Syngas LHV (CfD Eligible) Continuous syngas measuring Stable combustion Approx. 5.9 MJ/m 3 N based on 9.1 MJ/kg-waste refer to N.Tanigaki et. al. Waste Management 1,800 8
