Abstract
This paper proposes an effect of air-flow on bio-drying process of municipal solid waste (MSW). Properties of MSW are considered as the moisture content and optimal air-flow for bio-drying process. The organic MSW is an alternative way to recycle and transform the organic solid waste into energy. The objective is to determine the bio-drying properties in forms of air-flow rate for the organic MSW in order to decrease the humidity and to determine the optimal air flow rate for bio-drying that can be brought to reduce the humidity before storing in the warehouse. This paper presents an air-flow model of organic MSW for bio-drying that is suitable for the amount of organic solid waste decreased the humidity of the organic waste. Organic MSW is the household food waste for turning the food waste to energy in forms of biomass. 200-Litre Plastic barrel drum is used for experimental model with the different weight of MSW mass between 5 to 50 kg in the closed system. Experiments are performed at the air-flow volume and the different weight of organic solid waste. Empirical results show that the air-flow rate is proportional to the air inlet volume, which if the mass of organic solid waste increases, temperature and humidity will increase. It found that 30 kg of organic solid waste mass and 60% volume of plastic barrel drum with the air-flow rate of 24.39 m3/kg/hr or 430.67 CFM per 30 kg of MSW mass can achieve the lowest humidity at 11.8%.
