A method and a system for energizing household waste mixed with organic waste of the present invention relate to a mechanical-biological waste treatment (MBT) method, the method for energizing household waste comprising: a household waste crushing step (S10), an anaerobic digestion step (S20), a dehydration step (S30), an aerobic fermentation drying step (S40), a hot air drying step (S50), and a solid fuel manufacturing step (S60). A method for treating the household waste with the MBT method uses an energization method and an energization system, wherein the energization method comprises an electricity generation step (S20-1) for generating the electricity by using the biogas produced in the anaerobic digestion step (S20), and the energization system comprises: a waste pit (10), a household crusher (20), a digestion tank pump (30), an anaerobic digestion tank (40), a biogas refining means (410), a gas storage tank (420), a gas generator (430), a waste heat boiler (440), a dehydrator (50), a mixer (52), an aerobic dryer (60), a hot air dryer (70), a flammable waste selector (80), and a solid fuel molding machine (90). Accordingly, a production of solid fuel with good quality and a production of electric power using biogas can be simultaneously performed; operating costs can be reduced and the solid fuel can be more effectively produced by using the waste heat produced in the electric power generation process in the solid fuel generation process; and the MBT method can be activated. |
