  abstract = {{P}opulation growth, urbanization, and changing consumption patterns are contributing to an increase in household waste production, particularly in sub-{S}aharan {A}frica. {C}omposting of biowaste presents a sustainable solution by reducing the volume of waste sent to landfills while enriching the soil. {T}he main objective of this study was to evaluate the suitability of solid household biowaste for composting in market garden crops in {D}olisie (the {R}epublic of {C}ongo). {S}pecifically, the study aimed to (i) assess the production and management practices of solid household waste in relation to socio-economic factors, (ii) analyze the chemical composition of solid household biowaste and its concentration of trace elements ({TE}s), and (iii) determine the potential phytotoxicity of solid household biowaste across different production seasons. {I}n this study, wastes were collected from 40 households over a 60-day period, with daily sorting conducted during both the dry and wet seasons. {U}sing a completely randomized design, various compost application rates were incorporated into the soil to conduct a germination test. {T}he quality of the biowaste and compost was evaluated through physicochemical analyses. {R}esults showed that approximately 90% of high-income households received regular waste collection services and practiced waste separation in contrast to middle- and low-income households. {T}he composition of the biowaste was primarily composed of fruit and vegetable scraps, with slight contamination by chromium and cadmium. {T}emperature, p{H}, and humidity levels showed similar trends during compost formation in both the rainy and dry seasons. {G}ermination rates were above 80% in all treatments across both seasons, indicating that the compost was mature. {O}verall, all physicochemical parameters of the compost met established quality standards, and trace element concentrations were below the recommended thresholds. {T}he study concluded that biowaste, once converted into compost, can be safely applied to agricultural soils without posing any risk of phytotoxicity or contamination to crops.},
