ABSTRACT
To promote the green development of the tobacco logistics industry and realize resource utilization
of its solid packaging waste, this study investigated plastic wrapping film (polyethylene, PE),
logistics cardboard boxes (LCB), logistics wood strips (LWS), and cigarette packaging paper (CPP)
as representative materials. Comprehensive analyses were conducted on their composition, surface
functional groups, morphology, crystal phases, chemical bonds, and pyrolysis behaviors. Furthermore,
the co-pyrolysis interactions and kinetic parameters of PE blended with LCB, LWS, or CPP were
studied. The results showed that PE is mainly composed of C, H, and trace O, with C-H and -OH
as dominant surface functional groups. In contrast, LCB, LWS, and CPP are rich in C, H, O, N, and S,
with major surface functional groups of C=O, -C-O, C-H, and -OH, and contain substantial mineral
particles or additives. PE displays high thermal stability, decomposes within a narrow temperature
range (407~485°C), and produces negligible solid residue after pyrolysis. During co-pyrolysis, there are
strong interactions between PE and LCB, LWS, or CPP. Notably, the presence of minerals or additives
in LCB can greatly mitigate the negative effects of PE softening, shifting the pyrolysis temperature
of both LCB and PE to lower regions and reducing their activation energies to 11.43 and 16.53 kJ/mol,
respectively. The study demonstrates that co-pyrolysis is a feasible approach for the resource utilization
of solid waste from the tobacco logistics industry.
