Machine of a biomass gas engine.

We manufacture and sell biomass power generation equipment, carbonization equipment, semi-carbonization equipment, and more.

Biomass power generation uses wood biomass such as construction waste and thinned wood, as well as waste such as food waste and food processing residues, as fuel. It offers the following benefits:

  1. Energy recycling

    By reusing materials that would normally be discarded as fuel, biomass power generation contributes to reducing environmental impact from a resource circulation perspective.

  2. Weather-independent power generation

    Since it is not affected by weather, biomass power generation can secure a more stable power generation compared to other natural energies such as solar and wind power.

  3. Reduction in CO2 emissions

    While emitting carbon dioxide absorbed during the growth of plants and animals during the power generation process, this is part of a renewable cycle. It is possible to reduce the amount of carbon dioxide emitted during combustion compared to other fossil fuels.

  4. Support for the local economy

    Biomass power generation can support local industries such as agriculture and forestry. For example, by turning agricultural waste and debris into energy, new sources of income can be generated for local agriculture and communities, leading to economic revitalization.

From Japan to the World, An Overseas Network Spreading the Circle of Recirculation

It is no longer possible to discuss action against climate change in terms of the interests of individual countries.
There is an urgent need for action on a global scale. ZE Energy has run an operation trial on the first biomass power generation system in Japan, which we installed, and has used the results to begin exports to the USA. In future we plan to expand our operations to Europe, South America, Asia and around the world.
We will carry on working with local partners as we strive to improve the environment in many countries.
