PROCESS FOR PRODUCTION OF PHOSPHATE FERTILIZER, PHOSPHATE FERTILIZER, AND CARBONIZED PRODUCT OF DEAD DOMESTIC ANIMAL

摘要

Disclosed is a novel use application of a carbonized product of a dead domestic animal. It is found that a carbonized product of a dead domestic animal exhibits an excellent fertilizing effect for use as a phosphate fertilizer. The production of a phosphate fertilizer comprises a step of carbonizing a dead domestic animal. In the production of the phosphate fertilizer, it is preferred that the treatment atmosphere for the carbonization of the dead domestic animal be rendered oxygen-free before the carbonization is carried out. In the production of the phosphate fertilizer, it is also preferred that the treatment atmosphere for the carbonization of the dead domestic animal be purged by nitrogen to form a nitrogen atmosphere. A dead domestic animal can be utilized effectively as a phosphate fertilizer when converted into a carbonized product.
