Household food waste (FW) is a major biodegradable fraction of municipal solid waste and represents a potential feedstock for decentralized compost production. This study evaluated the feasibility of converting household FW into compost through laboratory-scale composting and compared six mixing formulations to identify a promising formulation among the tested treatments for further development of decentralized household FW composting systems. Food waste was collected directly from 60 households in Binh Duong Ward, Ho Chi Minh City, over seven consecutive days to characterize its generation rate and composition and to obtain representative feedstock for subsequent composting experiments. Six composting formulations were evaluated under controlled laboratory conditions, with three replicates per treatment. Food waste accounted for 66% of household municipal solid waste, with average generation rates of 0.861 kg/household/day and 0.203 kg/person/day. Plant-based materials represented 61% of the collected FW, indicating a substantial biodegradable fraction suitable for composting. The composting process was conducted for 28 days under aerobic conditions, with periodic monitoring of temperature, moisture content, and pH. The quality of the final compost was evaluated based on total nitrogen, available P₂O₅, available K₂O, organic matter, humic acid, Mg, Pb, Escherichia coli (E. coli), and Salmonella. Among the six formulations, T5, consisting of 80% FW, 10% loam soil, and 10% cow manure, showed the most favorable overall performance in terms of compost quality, particularly for nitrogen, organic matter, humic acid, and magnesium contents, while meeting the assessed microbiological safety criteria. The results demonstrate the feasibility of converting household FW into compost under the tested laboratory-scale conditions and identify T5 as the most favorable formulation among those evaluated, providing a basis for further development and validation of decentralized household FW composting systems.
