[0002] Aerobic composting is the process of aerobic bacteria absorbing, oxidizing, and decomposing waste under well-ventilated and oxygenated conditions. Aerobic composting is achieved by mixing organic materials with fillers in a certain proportion and, under appropriate moisture and aeration conditions, promoting microbial growth and degradation of organic matter, thereby stabilizing the organic matter. The primary purpose of aerobic composting is to convert organic waste into organic fertilizer, enabling resource recycling and reuse. Aerobic composting can also reduce waste volume, environmental pollution, greenhouse gas emissions, and improve soil quality and crop yield and quality.
