8. 3. Key Advantages for Deployment in Europe
(1) Flexibility
- Waste flexibility
- Feasible with Co-gasification
(2) Environmental Friendly
- Lower Emissions
- Contribution to “Circular Society”
(3) Sustainability
- CfD eligible
- High Power Generation
- Material and Energy Recovery from Waste
(4) Reliability
- Technology is well-proven
- Company
- Technology supplier or Turn-key supply?

9. 2.1. Flexibility Waste Flexibility CfD Eligible
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)
CfD Eligible
Continuous syngas measuring
Stable combustion
Approx. 5.9 MJ/m3N based on 9.1 MJ/kg-waste
refer to N.Tanigaki et. al. Waste Management
Syngas
400-
500 ℃
Sewage sludge
Bottom ash
Landfill Waste
Clinical Waste
600
-800 ℃
1,800℃

10. 3.2.1. Environmental Friendly
Low Emissions
Syngas combustion
(homogeneous combustion)
3Ts (Time, Temperature, turbulence)
Lower emissions such as PCDD/DFs,
HCl and SO2 have positive impact
for achieving permissions.
(2) Energy and Material Recovery from Waste
- Recycling material from waste without further post- treatment
- Minimizing non-recyclables and landfill amount
- Contributing to “Circular Society” or “Zero Waste”

11. 3.3.1. Sustainability - Energy from Waste -
Horizontal Boiler
η : >28%
(11 MJ/kg, 10t/h x 2 lines)
Dust Removal:
Rapping system
Shower Cleaning
Soot Blower for Economizer
Lower maintenance problems
Combustion chamber is also the part of the boiler

12. 3.3.2. Sustainability - Material Recovery -
slag
Concrete block
metal
Slag
Natural sand
Soil
Materials of Iron industries
Counterweight for construction machine
Interlocking block
Marine Block

13. 3.4.5. Reliability Technical Reliability
Should have commercial plants, not demonstration
Well proven
Should know “WASTE”
Company Reliability
Should have strong financial condition
Capability for EPC
Single responsibility
=> Bankable technology
(3) Operation support
Operating experience
Well-developed supporting system

14. 3.4. Reliability - References -

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

17. 3.4.5. Reliability - Operating Support -
(1) PlantPAD
Monitored operating condition remotely
Inspection data is recorded
Checking operating data
- ITV
- Historical trend data
- On-time operating condition
easier maintenance management
(2) Predictive Operating
Many operating records can predict the operating conditions.
Several parameters are picked up for predictive operation.
Less operation load
These supporting system lead easier “O&M” of gasification technology

18. 4. 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.
Driving factors of waste gasification for deployment are
(1) Flexibility of waste
(2) Environmental Friendly
(3) Sustainability (Energy and Material recovery)
(4) Reliability
Especially, our waste flexibility have great possibility to contribute to “Circular Society” and to improve feasibility of the project.
