<p>PROBLEM TO BE SOLVED: To use the calorie of a conditioner for primary fermentation and to reduce heat energy used, by mixing a fermentable organic substance such as an agricultural, fishery or stock raising waste with the excrement of domestic animal and a porous solid organic substance such as wood chips, subjecting the mixture to primary fermentation, screening the fermented substance by a sieve and recycling the solid organic substance not passing through the sieve, etc. as the conditioner to the medium of a primary fermentation tank to mix the conditioner with the medium. SOLUTION: A fermentable organic substance such as an agricultural, fishery or stock raising waste is mixed with the excrement of domestic animal and a porous solid organic substance such as wood chips or bark or its artificial substitute and subjected to primary fermentation. The fermented substance is screened by a sieve apparatus 5 and the solid organic substance not passing through the sieve, etc. is stored as a conditioner 6 in a conditioner tank 7, the conditioner 6 is repeatedly recycled and is used as a new agricultural, fishery or stock raising waste. Since the conditioner 6 is low in a water content, it contributes to the absorption of water and uniform mixing in the agricultural, fishery or stock raising waste.</p> |
