Daiwa House To Trial Food-Waste-Derived Biomethanol Power
Food Waste Biomethanol
Japan’s Daiwa House Industry will begin, from March 2027, a demonstration of what it describes as the country’s first power-generation system using biomethanol produced from food waste.
How the Process Works
The demonstration, run by the Osaka-headquartered company, converts food residue from an employee cafeteria at its Tochigi Ninomiya plant in Tochigi Prefecture into biogas, roughly 1 to 2 cubic metres a day from about 25 kilograms of food residue. The biogas is then synthesised into an aqueous biomethanol solution of about 58 percent methanol using a photo-oxidation technique developed jointly with Osaka University professor Kei Ohkubo, in a dedicated reactor with a total tank capacity of 135 litres across three tanks.
Powering the Expo Pavilion
The food waste biomethanol is transported to the GREEN×EXPO 2027 international horticultural expo held in Yokohama, where it fuels generation that supplies renewable electricity to the group’s pavilion, which it is showcasing as a closed-loop energy exhibit, for its heat-mitigating cooling equipment. The group also plans to procure additional mass-balance-certified, domestically produced biomethanol from Mitsubishi Gas Chemical so the pavilion’s entire power requirement is met from renewable sources.
Measuring the Trial
The demonstration spans the expo period from mid-March to late September 2027. The trial will verify biomethanol synthesis volume, methane conversion efficiency, cost, safety and regulatory compliance across the full route from synthesis and transport through to generation and use. Daiwa House projects the approach will avoid roughly 2.7 tonnes of CO2 emissions over the expo compared with electricity drawn from fossil sources.
Validation for Wider Rollout
The demonstration is designed to confirm the stability of the complete system before any broader rollout at the company’s own facilities. The underlying conversion technology emerged from a research collaboration Daiwa House began with Osaka University in 2022, and by closing the loop from cafeteria food waste to on-site renewable power, the project positions food waste biomethanol as a way to convert dispersed organic residue into a transportable liquid fuel for local energy use.
Turning Organic Waste Into Fuel
Klean Industries works across the food and organic waste chain, from gasification and energy-from-waste through to farm-to-table food production, closing loops between residues and energy. Projects that convert dispersed organic residue like food waste into a transportable liquid fuel sit squarely in Klean’s plant-engineering and feasibility capability.

Convert Food Waste Into Fuel
Food waste is a dispersed organic resource that can be converted into biomethanol and other renewable fuels instead of being landfilled or lost.
Klean Industries provides feasibility studies and plant engineering for energy-from-waste and organic-residue conversion projects.
