Abstract: Disclosed is a dry anaerobic composting facility. More specifically, disclosed is a dry anaerobic composting facility which mixes organic waste with a water controller by a pre-treatment unit, followed by pressing, grinding and substitution to convert the organic waste into an anaerobic substance, continuously subjects the anaerobic compound to fermentation, mixing/grinding, transport and discharge using an agitator by an anaerobic fermentation unit to improve production of compost, ages the produced compost by a post-aging unit to provide high-quality compost, and collects biogas produced by the anaerobic fermentation unit and uses the biogas as an energy source of a self-generator or a combined heat and power generator, to realize energy self-generation.
