| Outline of Final Research Achievements |
Composting is a recycling technology that converts livestock waste into organic fertilizer. Knowledge of basic scientific principles and appropriate methods for composting is essential for good compost production. However, these are often lacking in actual production sites. Therefore, this study aimed to develop a diagnostic technique that automatically determines whether composting is good or bad without requiring specialized knowledge at the compost production site. As a result, it was possible to diagnose composting as "good, acceptable, or not" by using the rate of heat production rate, etc., analyzed from the temperature in the initial composting stage.

| Academic Significance and Societal Importance of the Research Achievements |
良質な堆肥を生産するためには、堆肥生産現場で働くヒトの学術的知識や経験が必要不可欠である。しかしながら、畜産の規模拡大や人手不足などにより、熟練した堆肥生産者が少ない現状にある。そのため、堆肥化が上手くいかないという現場も多く見受けられる。本研究の成果は、この様な生産現場において、迅速に堆肥の発酵診断が可能となり、堆肥化施設の管理の一助となるとともに、科学的に裏打ちされた堆肥化技術の創出が図られる。
