Methane Fermentation System

Hitachi Zosen's methane fermentation systems convert organic waste such as kitchen garbage, pruned branches, paper, night soil, septic tank sludge, and discarded cooking oil into biogas, a source of green energy.

Methane Fermentation System “Hitz Kompogas System”


The system uses a combustible waste pre-processor to collect biomass material that can be converted into energy. It does not require any modifications to the existing waste collection setup.
Key features of the Hitz Kompogas System are listed below.

  1. Converts raw garbage into biomass and fermentation residue into compost simultaneously.
  2. Accredited by the Japan Waste Management Association in 2001 as a waste methane fermentation system in line with technical inspection and verification procedures.
  3. Biomass-derived biogas represents a renewable energy source that reduces CO2 emissions.

Methane Fermentation System “Mebius System”

Mebius collects energy both from night soil and septic tank sludge, and from high-concentration organic waste such as kitchen garbage.
Combining night soil treatment technology with methane fermentation technology, the system efficiently facilitates a sound material cycle.

Food Waste Methane Fermentation System “WTM System”

The WTM is a highly efficient, compact system that puts organic waste such as kitchen garbage and food waste through high-speed methane fermentation without the need for dilution water.
