Fossil fuel demand in Indonesia is estimated to grow significantly till 2050. On the other hand, environmental problems due to the massive increase in municipal solid waste have generated severe problems. Overcoming both issues has been a critical challenge for guaranteeing sufficient energy demand and a better future. Microalgae is a potential renewable energy source, and its blend with synthetic waste for energy generation will help to provide alternative energy and reduce environmental issues. This paper presented the changes in macromolecule contents of the blended material before and after combustion in a circulating fluidized bed combustor (CFBC) using Fourier Transform Infrared (FTIR) Spectroscopy. The results indicated that considerable difference spectra were observed. The different spectra are encountered between 3700-2400 cm-1. It is highly thought to be associated with the degradation of C-H, CH2, and CH3 in methylene during volatile combustion. For the residual matter after combustion, many spectra peaks are lost due to the loss of protein and lipid components from the biomass during the combustion process. The spectra changes were also discovered in the fingerprint area, at around 500-1700 cm-1, in correlation with C=O in the carboxylic group. These changes are related to the protein degradation of biomass. © 2024 American Institute of Physics Inc.. All rights reserved.
