Abstract As the world progresses, environmental problems emerge, such as the rise in global greenhouse gas emissions, specifically carbon dioxide (CO2) and improper waste management. To address these issues, this study aims to extract a natural polymer, chitin, from waste green mussel shells using a novel microwave-assisted extraction method. The extracted chitin was used as a support material for the functionalization of the adsorbent for potential CO2 capture. The process involves demineralization and deproteinization for mussel shells under the influence of a microwave unit. Results show that microwave power level 2 has produced the highest chitin yield (6.40%) among all the power levels. To enhance its CO₂ adsorption capacity, the extracted chitin underwent a sol-gel pre-treatment followed by functionalization with triethanolamine (TEA). Scanning electron microscopy (SEM) revealed a "brick wall-like" or flaky crystal structure with an increased surface roughness, suggesting successful TEA incorporation. Fourier-transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA) confirmed the presence of amine groups and enhanced thermal stability of the functionalized chitin. These characteristics are essential for CO₂ capture applications. This research demonstrates that waste green mussel shells coupled with microwave-assisted extraction can be a promising route in extracting chitin and its potential application to CO2 capture. Future work will focus on improving the pre-treatment process to produce a more suitable chitin support and optimizing the adsorbent's CO₂ capture capacity.
