Biomass Power Generation is a Power generation system that uses the heat from
the combustion of organic waste derived from plants and animals as fuel.

Does burning biomass fuel have a negative impact on the environment?

Biomass power generation is “carbon neutral”. Biomass fuel emits carbon dioxide (CO2) when burned, but this CO2 is absorbed by plants for photosynthesis and growth. So, the amount of carbon emitted by plants is considered the same as the amount of carbon absorbed. Thus, it does not increase or decrease the amount of CO2.

Biogas Power Generation

※Mouseover the images to show a explanation

Stores digestate after digestion.
Digestate can be returned to
farmland as liquid fertilizer.
Performs anaerobic digestion and
generates biogas.
Stores the generated Biogas.
Livestock manure, food waste, and
discarded crops are used as raw
materials.
Waste heat generated
during power generation can be
used for hot water.
Biogas is burned to
generate electricity.

There are many methods of Biomass power generation. Iwatec’s focus is on “Renewable Biomass” and we are working to extract energy from livestock manure and food waste with biogas power generation.

Digestate Utilization

The fermentation sludge that remains after Biogas is generated is
called digestate. Iwatec promotes effective ways for its utilization.

・Use as fertilizer

・Separate liquids from solids and use the solids as compost
and for livestock bedding.

・Promotes organic farming.

Benefits of Biomass / Biogas Power Generation

Reduce disposal costs by using digestate as fertilizer.

Biogas plant by-products can be reused as liquid fertilizer or compost. Disposal costs are also reduced in the process.
Energy saving by using the heat.

The exhaust heat generated during the conversion of biomass fuel to power can be used for heating purposes, further increasing the efficiency and saving energy.
Keeping the surrounding environment odor free.

Composting releases pungent odors until it is fully composted, but the digester in biogas plant is completely sealed, so odors do not leak out and contribute to improve the local environment.
