In China municipal solid waste and food waste production increase drastically with the rise in population and economic development, resulting in overwhelmed landfill waste management and adverse environmental impact. Alternative thermal treatment methods such as Pyrolysis are promising solutions to reduce waste volume, produce valuable energy, and minimize gas emissions. Therefore, co-pyrolysis of municipal solid waste (MSW) and food waste (FW) has the potential to revolutionize waste management and address energy challenges. In this study, the effect of heating rate, blending ratio and synergistic behavior on co-pyrolysis of MSW and FW were investigated using thermogravimetric analysis. The pyrolysis characteristics of MSW, FW, and their blends were analyzed using TG and DTG curves from room temperature to 900℃.Food waste blends at 10%,20% and 35% mass proportions were used, and experiments were conducted at varying heating rates (10,20 and 30℃/min). The samples were named as MSW100, FW100, MSW90FW10, MSW80FW20 and MSW65FW35. During single feed stock pyrolysis, it was observed that the initial temperature FW was lower than that of MSW while the terminated temperature of MSW was higher than FW due to the complex composition of MSW. An increase in heating rate led to an increase in MSW weight loss, while the opposite was observed for FW. The weight loss of the blends increases with an increasing FW blending ratio. This indicated the positive correlation between MSW and FW co-pyrolysis. The synergistic effect was positive for the MSW80FW20 blend at the intermediate temperature range (250℃-500℃), highlighting the advantage of combining MSW and FW. However, an antagonistic effect was observed at some blending ratio and high temperatures, emphasizing the need to optimize the co-pyrolysis process for different temperature ranges. These finding will aid in optimizing co-pyrolysis and designing pyrolysis reactors, thus contributing to the development of sustainable waste management strategies.
