Abstract

Indonesia, with a population of about 250 million people, not only produces large amounts of municipal solid waste (MSW) but also requires large amounts of energy. The conversion of MSW into solid fuel can be the solution to solve the problems. Indonesian MSW is dominated by high moisture-organic wastes such as leaf litter, food waste, vegetable waste, and fruit waste. The wet torrefaction is a thermal decomposition process that uses high temperature and high-pressure liquid to decompose biomass or MSW, which effectively increases the fuel properties of high moisture MSW. The purpose of this study was to determine the interaction of waste components consisting of lignocellulose and starch-based waste during the wet torrefaction process. After sample preparation, the wet torrefaction experiments were performed for two types of samples: individual samples and dual waste. The wet torrefied products were then dried and prepared for thermogravimetric analysis. These results provide the thermogravimetric analysis (TGA) of individual and dual samples to investigate the significance of interactions between waste components. Analysis of the significance of interactions was done by comparing the average curve of data from two individual samples (non-interaction) with the experimental data of dual samples (with interaction). The results showed that the interaction between leaf litter, vegetable waste, and fruit waste (lignocellulosic-based wastes) was relatively small and negligible during the wet torrefaction process. Meanwhile, food waste (starch-based) interacted with leaf litter, vegetable, and fruit waste during the wet torrefaction process. In formulating equations to predict the fuel properties of the wet torrefied products, it does not only consider the composition of waste and operating temperatures but also needs to consider the interaction between the components of waste, especially food (starch-based) waste.
