Biomass Utilization
Employing Biotechnologies to Ensure Harmonious
Coexistence with the Environment
Amid urgent calls for the realization of a recycling-oriented society, the generation of energy from organic waste is expected to be one of the technology-based environmental and energy solutions. We are striving to become the top runner in this field.
Hita City Biomass Resource Center
This facility boasts methane fermentation equipment utilizing fermentation technologies developed by Germany-based Linde plc. Moreover, the facility is equipped with a cogeneration system that effectively utilizes biogas and produces electricity and hot water. Excess sludge is treated by solubilizing equipment that reduces its bulk and produces a minimal volume of residue that can be used as a fertilizer.
Co-op Kobe (Food Waste Utilization System/PAMEDIS)
This facility accepts as raw materials sewage sludge and food waste (including breads, Japanese confectionaries and tofu) and collects biogas from them via wet and high-temperature methane fermentation at 55 deg C. In this way, the facility helps reduce the volume of waste that would otherwise be disposed of via incineration or landfill, supporting an energy-saving, clean and eco-friendly recycling process that generates power and heat.
Empirical research project of dynamic technology for renewable power generation at Higashinada Wastewater Treatment Plant, Kobe city (B-DASH Project)
The Project was implemented in Fiscal Year 2011 by the joint research consortium consisting of Kobe city and Kobelco Eco-Solutions, under the auspices of the National Institute for Land and Infrastructure Management (one of the public entities under the Ministry of Land, Infrastructure, Transport and Tourism). Through the project, we successfully demonstrated the following innovative results:
- augmentation of the biogas generation by making use of local biomass feedstocks.
- reduction of the construction and operation & maintenance costs by introducing the stainless steel digester as well as the new handling system for biogas purification, storage and pumping.
Digestion gas power generation project at Seibu-Joka center, Fuji city
The Project configuration is unique, which involves the digestion gas power generation unit that is privately-bulit-and-operated under the FIT (Feed-in-Tariff) scheme, in association with the renovation of publicly-owned existing digestion tank. The total system is highly energy-effcient, having a good combination of the digestion tank with the low-power mixing impellers as well as the power generation unit with high performance gas engine.
