This study explores the viability of utilizing municipal solid waste (MSW) and legacy waste as a renewable energy source through pyrolysis, akin to solid fuels. The heating value of MSW and legacy waste were found to be 37737.89 and 40432.84 kJ/kg, respectively. Proximate analysis shows that MSW fits within Tanner diagram parameters, eliminating the need for auxiliary fuel in pyrolysis. With 47.6 % and 44.16 % lignin content in MSW and legacy waste were deemed suitable for char production. Thermal degradation resulted in mass losses of 68 % for MSW and 82 % for legacy waste. The kinetic and thermodynamic assessment indicates lower activation energy (E) and Gibbs free energy (ΔG) for MSW (5.72 kJ/mol and 170.37 kJ/mol, respectively) compared to fossil fuels, suggesting faster reactions without additional energy requirement. MSW emerges as a promising alternative to fossil fuels, aligning with the United Nations' 2030 Sustainable Development Goals.
本研究探索了通过热解将城市固体废物（MSW）和遗留废物转化为类似于固体燃料的可再生能源的可行性。研究发现，MSW 和遗留废物的发热值分别为 37737.89 和 40432.84 kJ/kg。 初步分析表明，MSW 符合 Tanner 图参数，因此在热解过程中无需辅助燃料。MSW 和遗留废物中的木质素含量分别为 47.6%和 44.16%，适合生产炭。 热降解导致 MSW 的质量损失为 68%，遗留废物的质量损失为 82%。 动力学和热力学评估表明，MSW 的活化能（E）和吉布斯自由能（ΔG）分别为 5.72 kJ/mol 和 170.37 kJ/mol，低于化石燃料，这表明反应更快，无需额外的能量需求。MSW 作为化石燃料的替代品具有广阔的前景，符合联合国 2030 年可持续发展目标。
