PURPOSE: A system for resourcing waste generated gas based on a hydrate technology is provided to increase the recycling efficiency of energy and reduce the generation of greenhouse gas by recycling waste gas generated from anaerobic digestion facilities or landfills of small and medium sizes. CONSTITUTION: A methane gas mixture is extracted from waste generated gas(S100). Impurities contained in the methane gas mixture is eliminated in a pre-treating process(S200). The pre-treated methane gas mixture is concentrated(S300). The concentrated methane gas mixture is hydrated, and impurities are eliminated from the mixture in order to form and refine methane gas hydrate slurry(S400). The refined methane gas hydrate slurry is shaped, and the intensity of the shaped slurry is maintained(S500). A ice film is formed on the outer surface of the shaped methane gas hydrate to maximize the self preserving effect of the hydrate(S600). The ice film formed methane gas hydrate is stored at low temperatures(S700).
