Introduction to Organic Fertilizer Production via Household Waste and Feces Composting Fermentation with Semi-permeable Membrane Coverage

The resource utilization of household waste and livestock and poultry feces is a core part of circular agriculture and rural environmental governance, which effectively solves the problems of rural waste accumulation, environmental pollution and insufficient soil organic matter. The composting and fermentation technology of these organic wastes, coupled with semi-permeable membrane covering treatment, can efficiently convert waste materials into high-quality ecological organic fertilizer, realizing harmless treatment and resource recycling of wastes.

Household waste such as kitchen residues, fallen leaves and crop straws, together with livestock and poultry feces, are rich in organic carbon, nitrogen, phosphorus, potassium and various trace elements required for crop growth. Before fermentation, the raw materials are proportionally mixed and stacked to adjust the moisture content and carbon-nitrogen ratio to the optimal fermentation range, creating a suitable living environment for beneficial microbial flora. Through aerobic fermentation and composting, microorganisms decompose macromolecular organic substances in the raw materials, degrade harmful substances such as pathogenic bacteria, parasite eggs and residual impurities, and transform raw waste into stable, humus-rich organic fertilizer raw materials.

After full fermentation, aging and screening treatment, the finished organic fertilizer has loose texture, stable performance and rich humus. Applied to farmland, orchards and greening land, it can significantly improve soil structure, enhance soil water retention and fertilizer retention capacity, activate soil microbial activity, and improve crop yield and quality. This waste recycling model not only reduces the environmental pressure caused by domestic and breeding waste, but also replaces chemical fertilizers to a certain extent, reducing agricultural production costs and promoting the sustainable development of ecological agriculture.
