This research investigates the kinetic, product evolution, mechanism of polyethylene (PE), polypropylene (PP), and a simulated mixture plastic waste (SMP) via TGA/DSC–MS Py-GC–MS. The pyrolysis reactions were predominantly endothermic, main degradation stage PE, PP, SMP ranged from 389.85 to 502.17 °C, 374.91 495.15 368.30 496.29 respectively. kinetic results showed that polyolefin was identified be geometrical contraction models with apparent activation energies 224.31–235.32 kJ mol–1 for PE 199.00–207.66 follows first-order reaction models, its energy 185.29–199.54 mol–1. Polyolefin products only contain C4–C35 paraffin linear alkenes branch or cyclic PP. large amounts benzene radicals in tended form aromatics. behavior formation could make available practical implications reactor design parameter optimization.

Thermochemical co-conversion of biomass-plastic waste to biochar: a review

Green Chemical Engineering, Год журнала: 2023, Номер 5(1), С. 31 - 49

Опубликована: Март 15, 2023

Biomass and plastics are two of the most common municipal solid wastes globally that have continuously placed a burden on environment. It is therefore important they properly recycled. Thermochemical co-conversion offers valuable opportunity to recycle biomass simultaneously into biochar, which reduces time cost recycling them individually while producing material with wide range applications. This study review published literature discusses thermochemical co-processing plastic biochar. was observed co-pyrolysis co-hydrothermal carbonization commonly utilized technologies for this process. The characteristics different been thermochemically converted biochar were compared. properties resulting affected by feedstock composition, pre-treatment blending ratio, reactor's configuration, reaction temperature, presence catalyst. Most studies found treating feedstocks separately resulted in lower yield than processing together. created procedure has used as soil additive an adsorbent water treatment. Future perspectives suggestions, such necessity some technical advancement, biochar's economic benefits, improved government participation, raised social awareness, also made. These factors potential propel field great horizons.

Microplastics Derived from Food Packaging Waste—Their Origin and Health Risks

Materials, Год журнала: 2023, Номер 16(2), С. 674 - 674

Опубликована: Янв. 10, 2023

Plastics are commonly used for packaging in the food industry. The most popular thermoplastic materials that have found such applications polyethylene (PE), polypropylene (PP), poly(ethylene terephthalate) (PET), and polystyrene (PS). Unfortunately, plastic is disposable. As a consequence, significant amounts of waste generated, entering environment, undergoing degradation processes. They can occur under influence mechanical forces, temperature, light, chemical, biological factors. These factors present synergistic or antagonistic effects. result their action, microplastics formed, which undergo further fragmentation decomposition into small-molecule compounds. During process, various additives at plastics' processing stage also be released. Both negatively affect human animal health. Determination negative consequences on environment health not possible without knowing course processes products. In this article, we sources microplastics, causes places formation, transport particles, plastics often production storage, affecting said its
