The necessity to mitigate the environmental impact of recalcitrant organic residues (RORs) and harness the valuable bio-energy products has stimulated investigations on the application of pyrolysis technology in the treatment and recycling of RORs. In this study, based on the thermogravimetric analysis results, the ROR temperature requirement for the final decomposition was higher than 450 °C and ranged between 500–650 °C. Experiments on the ROR pyrolysis were conducted in a fixed-bed pyrolysis reactor at temperatures of 600–900 °C and a heating rate of 20 °C min⁻¹. Beneficial products such as char, gas, and bio-oil were obtained during the pyrolysis process. The analyzed biochar average pore diameter of 11.01 nm and surface area of 73.54 m² g⁻¹ reflect features than can enhance bioprocess technology performance and agronomy application potential. The pyrolytic oil analysis revealed a low heating value (LHV) of 28.4 MJ kg⁻¹ at 600 °C, offering the possibility to address the bio-energy challenges. The results showed that pyrolysis of the ROR from a food waste (FW) treatment facility is a beneficial approach offering waste-to-resources opportunity.

减轻顽固性有机残留物（RORs）对环境的影响并利用有价值的生物能源产品的必要性刺激了对热解技术在RORs的处理和回收中的应用的研究。在这项研究中，基于热重分析结果，最终分解的ROR温度要求高于450°C，范围在500–650°C之间。ROR热解实验在固定床热解反应器中进行，温度为600-900°C，加热速率为20°C min ^-1。在热解过程中获得了有益的产物，如焦炭，天然气和生物油。分析的生物炭平均孔径为11.01 nm，表面积为73.54 m ²  g ^-1反映的特征比可以增强生物加工技术的性能和农学应用潜力更大。热解油分析显示600°C时的低发热量（LHV）为28.4 MJ kg ^-1，为应对生物能源挑战提供了可能性。结果表明，食物垃圾（FW）处理设备对ROR的热解是一种有益的方法，可提供从废物到资源的机会。
