Electricity Generation

Converting the Priceless Resources of
Waste and the Power of Nature into Energy

We recover energy from waste in a highly efficient manner and use it for power generation and heat utilization.
In addition to the existing facilities, a new methane fermentation facility that generates power from biogas emitted from food scraps and other organic waste began operation in November 2022. We are also constructing power generation facilities that utilize the thermal energy generated from the co-firing of various waste and biomass resources. We will continue to create energy from the priceless resources of waste, and actively work to build Local Circular Ecological Spheres.

Aiming for a sustainable society
through the effective use of waste-to-energ

Waste biomass power generation

Power generation and heat utilization using waste as an energy source

Biomass is a general term for organic energy resources produced from plants, animals,
and other living organisms, generally excluding fossil fuels. We supply heat and electricity obtained from various waste materials in addition to biomass resources, both within and outside the group.

Facilities
  • Mie Recycle Center Energy Plaza
    （Iga City, Mie Prefecture)

    Permitted capacity: 636 t/day (incineration), 187 t/day (roasting)
    Rated power generation capacity: 4,050 kW

    This facility supplies heat and electricity obtained from waste, both within and outside the group. Incinerated ash is recycled into materials for civil engineering pur-poses in a roasting furnace. This unique recycling system combines the effective use of energy and mate-rial recycling.

  • DINS Kansai Bioethanol Recycle Center
    (Sakai City, Osaka Prefecture)

    Permitted capacity: 86 t/day (incineration)
    Rated power generation capacity: 1,950 kW

    This facility produces bioethanol from biomass materi-als such as waste wood, waste juice, and waste alcohol. Waste wood that is not suitable as a raw material for ethanol is recovered as steam and electrical energy in a power generation facility within the plant, and used within the facility. Any surplus electricity is sold back to the grid.

  • Miki Biomass Factory
    (Miki City, Hyogo Prefecture)

    Permitted capacity: 440 t/day (incineration)
    Rated power generation capacity: 11,700 kW

    This facility is under construction with the aim of start-ing operation in 2023. It will generate power by co-fir-ing various waste materials and biomass resources such as waste wood and food scraps generated in the region. In addition to selling surplus electricity back to the grid, we are also considering ways to return the benefits of the factory back to the local community, such as through the use of thermal energy.

Biogas power generation

Electricity generation using methane recovered from organic waste

Biogas power generation is a system that generates electricity by recovering methane from biomass resources, using gas engines.

Facilities
  • Iga Recycle Center Methane Fermentation Facility (Iga City, Mie Prefecture)

    Permitted capacity: 320 t/day
    Rated power generation capacity: 1,980 kW

    At the methane fermentation facility, biogas is extracted from organic waste (food scraps, organic sludge, liquid waste, etc.) through the action of methane bacterium, and this biogas is used for power generation.

Supplying heat to the region

Trans-Heat Container

We developed the Trans-Heat Container System. This system can be used to store thermal energy in a small container, which in the past could only be transported using a purpose-built large trailer. The system delivers approximately 1,820 mega-joules of thermal energy per transportation to the Sunpia Iga hot spring hotel facili-ty, where it is used for the natural hot spring.

Reuse of landfill-completed sites

Solar power generation

Creating renewable energy by utilizing former landfill sites

Approximately 5.5 million kWh of electricity is generated annually.
