Synergetic Effects during Co-Pyrolysis of Sheep Manure and Recycled Polyethylene Terephthalate

Abstract

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−1 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.

Emission Assessment of Agro-Waste Combustion

“…As can be seen from the figure, similar CO2 emission values were obtained for all biomass. Due to the CO2 neutral feature of biomass fuels, their European Journal of Science and Technology e-ISSN: 2148-2683 3 impact on global warming can be considered as negligible (Akyürek, 2019(Akyürek, , 2021.…”

畜禽粪污资源化处理与种养循环一体化研究与思考

“…种养循环系统 中畜禽粪污处理对系统氮循环影响较大, 其资源化利 用也是近年热点, 各国针对畜禽粪污资源化进行了大 量研究. 在美国, Akyürek等人 [50] 使用热重分析仪 (TGA), 研究了循环羊粪塑料共热解行为, 结果表明共 热解是生产绿色能源的可行技术. Reddy等人 [51] 研究 发现, 粪污资源化可以显著提高土壤生物活性和养分 循环, 提高了利润, 并加强了农业系统的可持续性.…”

Syngas Fermentation: Cleaning of Syngas as a Critical Stage in Fermentation Performance

“…Syngas is produced from pyrolysis/gasification using different materials as inputs. The great advantage of thermal processing is its versatility, being capable of treating fossil sources such as oil sludge, a viscous residue derived from crude extraction and processing, heavy oil, coal, plastics and also renewable sources such as biomass, manures, and organic wastes in general [23][24][25][26][27][28]. The gas produced has a low volumetric energy density mainly due to H 2 and CO.…”
