TECHNOLOGY FOCUS - BIOTECHNOLOGY - Preferred Apparatus: The fermenter is used such that the raw material is dried continuously. The scoop type fermenter in the shape of the cross-sectional rectangle having upper surface with an opening and bottom surface or flat type fermenter with bottom surface and side walls is used. The apparatus comprises rectangular outer frame with a hollow opening in the upper end and several partition walls arranged in parallel manner at regular intervals such that organic substance raw material is segmented in the apparatus. The partition wall comprises a double-sided partition material and inner surface that allows air flow in upward and downward directions. At least one part of each wall surface of the outer frame is provided in a grid form and mesh shape, and has air permeability equivalent to the partition surface material. The structural materials of the fermenter are made up of any one or combination of metal-meshes chosen from timber and stainless steel, carbide, ceramic and plastics. An air channel is created by maintaining a gap between the structural materials and structural materials with adhesive agent. The organic raw material added one by one to the bottom of the apparatus is dried by keeping the raw material in motion and the movement is accomplished by plowing organic raw material using a stirrer provided with rotary blade or scoop type rising blade.    TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Composition: The water content of the raw organic material is adjusted to 45-70% and the total specific gravity of the raw material is adjusted to 0.3-0.7, such that raw material is fermented and dried to obtain granular powder having water content of 38% or less within 20 days. Preferred Method: The raw material (organic refuse) is inoculated with heat-sterilized microbial inoculum and fermenting the raw material. The mushroom is grown in culture until mushroom gets disconnected with the hypha and the harvested mushroom culture is inoculated with the mushroom waste cultivation bed. The dried organic material is obtained in the form of granules using molding machine by applying pressure. EXAMPLE - No suitable example given.
