PROBLEM TO BE SOLVED: To provide a low-cost method for suppressing the generation of odor due to ammonia or amines in a composting process, particularly the generation of ammonia, without adversely affecting microorganisms contributing to decomposition. SOLUTION: For example, polycaprolactone is added to compost or compost raw material as a polymer substance that generates an organic acid by decomposition in the composting process. |
