<p>The present invention relates to an environmentally friendly and high efficiency solid fuel production method using high-water-content organic waste, and, more specifically, relates to a solid fuel production method using high-water-content organic waste, the method comprising: (a) a waste mixing step in which high-water-content organic waste and municipal waste are introduced into a Fe-based reactor and mixed; (b) a hydrolysis step in which high temperature steam is added to the reactor and the mixture of organic waste and municipal waste is placed under pressure and is then stirred in the pressurized state so as to hydrolyse the mixture; (c) a pressure-reducing step in which the steam in the reactor is discharged and the inside of the reactor is rapidly reduced in pressure and left to stand in such a way as to give the organic waste from step (b) a low molecular weight or in such a way as to enlarge the specific surface area of the municipal waste from step (b) and thereby break apart same; (d) a vacuum or differential pressure step in which the reactor is placed under vacuum or differential pressure, and the water content of the reaction product from step (c) is removed; and (e) a solid-fuel forming step in which the reaction product from step (d) is subjected to natural drying and compression moulding so as to produce a solid fuel having a water content of between 10 and 20%.</p> |
