8 2.1. Flexibility 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 Sewage sludge Bottom ash Landfill Waste Clinical Waste 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

9 2.2. Reliability (1) Technical Reliability Should have commercial plants, not demonstration (References) Well proven (Capacity, Operating conditions) Should know WASTE (2) Company Reliability Should have strong financial condition Capability for EPC Single responsibility => Bankable technology Especially for gasification technologies, the following are the most important factors for deploying in the market; 1) operating data (operating conditions) 2) Commercial References and Scale-up (capacity) 9

10 2.2. Reliability - First two years operation - - First two years operation works well. - Due to the local issues*, the maintenance and other shut-down periods are longer than that in Europe. However, the ratios of unexpected shut-down are quite low. * boiler and turbine inspection period, lack of waste and maintenance etc. 1st year 2nd year - No.1 No.2 No.1 No.2 Operation hours hours unexpected Shut-down hours maintenance etc. hours MCR t/h 9.4 Average t/h * When the shut-down is shorter than 1 hour, it is counted as 1 hour 10

11 2.3. Reliability - Measures for Scale-up of Gasification - 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 expands its capacity, during 35 years and leach the capacity of 14 t/h per line. 11

12 2.3. Reliability - References - 46 references 37 years operation 10, ,000 t/a 12

13 Shin-Moji Plant Location / Purchaser Kitakyushu City, Japan Fuel Municipal solid waste Incombustibles Sewage sludge Capacity 3 x 10 t/h kj/kg Largest Waste Gasification Plant in operation Year of Start Up 2007 NSENGI Scope of Supply Full Turn key, Operation & Maintenance 13

14 Narumi Plant - Co-Gasification of Bottom Ash - Location / Purchaser Nagoya City, Japan Fuel Municipal solid waste Bottom ash Incombustibles Combustibles Capacity 2 x 11 t/h kj/kg Year of Start Up 2009 NSENGI Scope of Supply Full Turn key BTO Operation & Maintenance Bottom ash recycling is not allowed. The municipality has no landfill site Need solutions. Co-Gasification and recycling 87% reduction of final landfill amount 14

15 Kita-Nagoya Plant Location / Purchaser Kita-Nagoya City, Japan Fuel Municipal solid waste Capacity 2 x 14 t/h Largest Waste gasification Year of Start Up - (awarded at 11 th Dec. 2015) NSENGI Scope of Supply Full Turn key BTO Operation & Maintenance 15

16 3. Summary NSENGI Group has a capability to provide various solutions for clients. (gasification, incineration and others) The Direct Melting System can achieve both the energy and material recovery from waste without any pre- and post treatment. Technology reliability of gasification such as capacity, availability and performance is the key issue for deploying in the UK. Especially, scale-up of gasification technology is one of the key technical issues. NSENGI has overcome this issue with scaling-up step by step. The Direct Melting System, which as the proven capacity and availability, is one of the most reliable gasification technology in the world. 16
