| Summary: | A laboratory scale mechanical composting system was designed to investigate how aerobic composting could contribute to solid waste disposal of biodegradable materials producing soil conditioner as a product. Solid wastes such as banana peelings and left over rice were used and had undergone pretreatment like grinding and drying before decomposition inside the digester. aerobic condition was attained through agitation and aeration of the compost during decomposition. Volume and mass reductions were determined after pretreatment (grinding and drying) and after decomposition. the C:N ratio reduction due to degradation of the refuse was also determined. The temperature and pH profiles were used to determine the degree of decomposition of the humus produced. Soil conditioner was produced after a nominal decomposition of one week and was found out to be stabilized. |
