NOVELTY - Disposing of waste includes the addition of mycelial carrier support to the waste to be decomposed. The mycelial carrier support comprises 5-20% mixture of fungi and bacteria, and 80-95 wt.% porous carrier of 3-30 mesh having a pH of 6.5 to 9.5.    USE - The invention is used for disposing waste including sludge from both water supply and sewarage, livestock excreta such as fowl droppings and pig excrement, carcasses of livestock, agricultural waste such as dried grass and rotten crops, and raw garbage such as both animal-based and vegetable-based food residue.    ADVANTAGE - The waste can be completely decomposed and disposed of in a short period. In case of using the customary fermented accumulation method, it takes 1-6 month(s) to ferment the waste completely, but by using the invention, the waste can be disposed of within 7-14 days. Therefore, the waste can be efficiently disposed and effectively recycled. Since compost has effects in promoting the growth of plants and in preventing the obstacles of continuous cropping, it can be used as plant activator and as soil regulator. The smell of the waste can also be reduced down to 1/2 to 1/100, thus reduces odor. The volume of the waste can be reduced to 1/10, thus volume can be reduced.    DETAILED DESCRIPTION - A waste is disposed by:    (a) providing a mycelial carrier-support comprising 5-20% mixture of fungi and bacteria, and 80-95 wt.% porous carrier of 3-30 mesh having a pH of 6.5 to 9.5;    (b) adding 5-40 wt.% of mycelial carrier support to the waste to be decomposed;    (c) fermenting the waste by agitating at more than 15 degrees Centigrade; and    (d) allowing the temperature to rise and continue fermenting the waste at a temperature maintained at 55-80 degrees Centigrade by aeration to decomposed the waste.    The porous carrier can be charcoal, active carbon, coal, coke, active coke, peat, palmculite, perlite, or bentonite. The mixture of fungi and bacteria contains Thermoactinomyces, Thermonospora, Actinbifida, or Thermopolyspora, and Bacillus subtilis thermophile as a majority of the bacteria.
