BEB’s garage‐type dry fermentation process is mostly involved and used in biogas projects for municipal organic waste and straw treatment. The advantages of this process include no requirement of agitators, pumps and feeding pipes. The digestion will not be affected by any unsuitable materials such as plastics, wood blocks and sandstones; therefore the process does not require any special separation equipment before digestion. As there are no operating components such as agitators existing in the fermentation room, the system possesses very high reliability.
