Effective Use of Energy

1. Generating Energy from Refuse and Reducing CO2

Generating Energy from Refuse and Reducing CO2

A Refuse Incineration Plant is an Energy Generating Plant

When refuse is incinerated, a large amount of heat is generated.
The heat is converted to steam that is transferred to generators and used to make electricity.
Refuse incineration plant could, therefore, be called an energy generating plant.

Effective Use of Energy

Waste-to-Energy Systems Contribute to Reducing CO2

Japanese Ministry of the Environment is promoting waste-to-energy systems. Hitachi Zosen’s experience in this field goes back to 1965 at when we have installed first large scale refuse incineration plant in Japan.
Hitachi Zosen has built 181 garbage incineration plants. At present, 44 are generating power.
These 44 plants have a generating capacity of 260,000 kW in total, and contribute to reducing CO2 by 1.2 million tons/year. This is equivalent amount of CO2 emitted by approximately 220,000 households per year (as of April 1, 2010).

Maishima Incineration Plant

Maishima Incineration Plant, built in 2001 at Osaka City, is generating 32,000KW of electricity which is one of the largest power generating plants among any such facility in Japan and we are very proud of.

Promoting the Introduction of Waste-to-Energy Systems

Japanese Ministry of the Environment is seeking to further reduction in emissions of greenhouse gases. To that end, one of its priority policies is to promote the introduction of high-efficiency waste-to-energy systems, which will be instrumental in achieving a recycling-based society. The subsidy given by the Ministry to municipalities who are introducing high-efficiency waste-to-energy systems is increased by 17%. This can be an incentive to further promoting the system.
