Optimal Aeration Management Strategy for A Small-Scale Food Waste Composting

Food waste is a significant contributor to greenhouse gas emissions when it ends up in landfills. Composting is a sustainable solution to this problem, but it requires controlled and continuous airflow for optimal performance. The objective of this study is to investigate the effect of aeration rate...
