Résumé
Highlighting the rejects of the rejects, this study focuses on refuse-derived fuels (RDF) generated from non-recyclable municipal solid waste. Unlike wood or coal gasification, RDF in its natural state is a poor fuel source, containing different types of materials, such as paper and plastic, which exhibit distinct chemical properties, thermal properties, and energy content. The efficiency of RDF gasification is limited by its heterogeneity. To enhance the yield and efficiency of the gasification process, torrefaction is being considered as a pre-treatment process. Due to the difficulty of predicting the impact of thermochemical processes on RDF, a monitoring system is required to better understand and control the macro-composition of individual fractions. In this study, RDF fractions are studied independently towards modelling a relation between the percentage composition of each RDF individual fraction and the effects of torrefaction. These include papers, plastics, cardboard, other organics, and fines (<1 cm), which made up more than 90% of the RDF as received from waste sorting centres. Through thermogravimetric analysis, the effects of torrefaction on mass loss have been obtained for all fractions at 200°C, 250°C, 300°C, and 350°C. Using the main RDF fractions, a recombined RDF was produced and torrefied in this study. Instead of a synergistic effect, an additive effect was observed when comparing the mass loss obtained in the recombined RDF to the expected theoretical mass loss computed based on the composition of each fraction and its individual mass losses. From 200°C to 300°C, the experimental and theoretical values closely align, with absolute differences of only 0.74%, 0.04%, and 0.28% at 200°C, 250°C, and 300°C, respectively.
