Continuous growth in energy demand and plastic waste production are two global emerging issues that require development of clean technologies for energy recovery and solid waste disposal. Co-pyrolysis is an effective thermochemical route for upgrading waste materials to produce energy and value added products. In this study, co-pyrolysis of sheep manure (SM) and recycled polyethylene terephthalate (PET) was studied for the first time in a thermogravimetric analyzer (TGA) in the temperature range of 25-1000 °C with heating rates of 10-30-50 °C min under a nitrogen atmosphere. The synergetic effects of co-pyrolysis of two different waste feedstock were investigated. The kinetic parameters are determined using the Flynn-Wall-Ozawa (FWO) model. The results revealed that the mean values of apparent activation energy for the decomposition of sheep manure into a recycled polyethylene terephthalate blend are determined to be 86.27, 241.53, and 234.51 kJ/mol, respectively. The results of the kinetic study on co-pyrolysis of sheep manure with plastics suggested that co-pyrolysis is a viable technique to produce green energy.
能源需求和塑料垃圾产量的持续增长是两个全球新出现的问题，这需要开发用于能源回收和固体废物处理的清洁技术。共热解是一种将废料升级以生产能源和增值产品的有效热化学途径。在本研究中，首次在热重分析仪（TGA）中，于25 - 1000 °C温度范围内、10 - 30 - 50 °C/min升温速率以及氮气气氛下，对羊粪（SM）和回收聚对苯二甲酸乙二酯（PET）的共热解进行了研究。研究了两种不同废料原料共热解的协同效应。使用弗林 - 沃尔 - 小泽（FWO）模型确定动力学参数。结果表明，羊粪与回收聚对苯二甲酸乙二酯混合物分解的表观活化能平均值分别确定为86.27、241.53和234.51 kJ/mol。羊粪与塑料共热解的动力学研究结果表明，共热解是一种可行的绿色能源生产技术。
