Abstract
This study evaluates the effectiveness and operational cost of a newly developed ''Compost Heating System'' designed to enhance composting efficiency in cold regions. During rigorous winter tests, where temperatures dropped below -20 ˚C, the system successfully facilitated smooth composting processes, effectively mitigating the delays and stagnation typically observed during cold seasons. Even after the compost was moved to areas without the heating system, the temperature continued to rise similarly, indicating the system's significant contribution to the overall composting process. Economically, the system operates at 1402 yen per unit per day, a comparatively low cost compared to traditional methods that rely on heated air blown through ventilation pipes. These results strongly suggest that the Compost Heating System offers a practical and cost-effective solution for enhancing composting performance during severe winters, making it a promising advancement in the management of composting facilities in cold climates.
