WtE - Incineration SystemWtE - Incineration System

Municipal Wastes, Industrial Wastes (Waste of Plastics, Tires,

Fiber, Paper and Timbers) and Agricultural Wastes

• Thermally recycled to Electricity and other Thermal Energies

(Cold water, Hot water and Steam)

• Regarded as a Substitute of Fossil Energy to reduce GHG • Regarded as a Substitute of Fossil Energy to reduce GHG emission.

In Japan short of natural resources, historically,

• Wastes have been converted to fuels

• Infrastructures to thermally recycle wastes to energies

have been developed ever since ’60s.

BenefitsBenefits

Improve residential environment and health By regularly collecting wastes and incinerating them with sophisticated exhaust gas treatment system, residential environments evolve into even cleaner cities.

Contribute to national energy securityWaste-to-Energy infrastructures to provide energy resource substitutes contribute to the development of national energy security and portfolio.

Develop CDM SchemeThermal waste recycling, which replaces conventional landfill waste treatment system emitting massive methane gas, contributes to the reduction of GHG emission.

Thermal recycling from biomass related wastes such as Agricultural wastes, Municipal wastes etc. contributes to the reduction of GHG emission.

FEATURES OF VHP SYSTEMFEATURES OF VHP SYSTEM

Variable heat and power operation is available without shut down.This Gas Turbine cogeneration normally operates at the point of 4.2MW power with 8.7t/h

steam recovered form its exhaust gas energy. It is variable however that you can boost the

power up to 6.1MW anytime by injecting the excess steam to the gas turbine combustion

liner, when you need more power and less steam (e.g. Summer season), instead of just

dumping the steam. The system can be variable at anytime without system shut-down to

match and follow your steam demand in time
