Biomass power generation is a method of power generation that generates fewer harmful substances during combustion than using fossil fuels.
In the operation of our biomass power generation business, we design and construct air pollution control devices that clear statutory emission standards for air pollutants such as nitrogen oxides, sulfur oxides, dust and soot generated when burning biomass fuels, and strive to ensure that local residents can feel safe.

Solar PV minimizes the need for earthworks and reduces the amount of waste such as mud, sand and felled trees at the time of construction. In addition, the mud, sand and felled trees produced are reused as much as possible at the power plant site.
In biomass power generation, we recycle ash generated by the combustion of biomass fuels.
Akita Biomass Power Plant uses construction waste as a heat source for dryers used in the process of drying biomass fuels such as wood chips before burning them in the boiler.

From the perspective of effective use of water resources, RENOVA strives to minimize the amount of water resources used in the construction and operation of its power plants as much as possible, and to return the water resources used to nature in a form with low environmental impact.
For example, in order to prevent the outflow of oil and other waste from power plants into the oceans, we have taken measures such as installing oil-water separation tanks consistently, from the time of initial construction.
Many of RENOVA’s biomass power plants do not employ the usual water-cooling method (which uses seawater or industrial water to cool the steam discharged from turbines) but an air-cooling method that cools the boiler with air, with almost no use of water. We believe that this contributes to the effective use of water resources and the elimination of the effects of hot wastewater effluent.
Using the air-cooling method has enabled an 84% reduction in water consumption* compared to water-cooled power plants.

With its mission, “To create green and sustainable energy systems for a better world,” RENOVA is fully dedicated to contributing to reducing CO2 emissions through the development of renewable power plants and the expansion of the scale of their operations toward decarbonization.
