Herein, the pyrolysis of mulching film waste (an agricultural plastic waste) with cattle excreta (livestock organic waste) was investigated as the efficient simultaneous treatment of plastic and organic wastes. For pyrolysis of mulching film waste or cattle excreta, an increase in temperature increased the yield of non-condensables and decreased the yield of condensables or solid residue. The mulching film waste-derived pyrolytic product was composed largely of a wide range of hydrocarbons (C₁–C₄₄), while the cattle excreta-derived pyrolytic product was composed of a variety of chemical groups such as oxygenates, polycyclic aromatic compounds, N-, S-, and B-containing compounds, and halogenated compounds. Pyrolysis temperature had no significant effect on the selectivity toward each chemical groups found in the condensables derived from either the mulching film waste or cattle excreta. The addition of the cattle excreta to the pyrolysis of the mulching film waste increased the yield of non-condensables and enhanced selectivity toward H₂ between 500 °C and 900 °C, compared to the pyrolysis of the mulching film waste only. The pyrolysis of the mulching film waste/cattle excreta mixture led to the condensables with lower contents of N, S, B, and halogens than the pyrolysis of a single feedstock. This study is to propose thermochemical conversion pathway of agricultural plastic waste along with livestock organic waste as an effective strategy for waste-to-resources.

在此，研究了用牛排泄物（牲畜有机废物）热解地膜废物（农业塑料废物）作为塑料和有机废物的有效同时处理。对于地膜废物或牛粪的热解，温度升高会增加不可冷凝物的产量并降低可冷凝物或固体残留物的产量。地膜废料衍生的热解产品主要由多种碳氢化合物（C ₁ -C ₄₄)，而牛排泄物衍生的热解产物由多种化学基团组成，例如含氧化合物、多环芳族化合物、含 N、S 和 B 的化合物以及卤化化合物。热解温度对来自地膜废物或牛排泄物的可冷凝物中发现的每种化学基团的选择性没有显着影响。将牛排泄物添加到地膜废料的热解中提高了不凝性物质的产量并增强了对 H _{2 的}选择性500 °C 到 900 °C 之间，与仅地膜废料的热解相比。与单一原料的热解相比，地膜废物/牛排泄物混合物的热解导致可冷凝物的 N、S、B 和卤素含量更低。本研究旨在提出农业塑料废物和牲畜有机废物的热化学转化途径，作为废物转化为资源的有效策略。
