“…Rago et al. ( Rago et al., 2020 ) have performed torrefaction of mixed solid wastes, including LDPE at temperature of 300 °C for 30 min. They found that co-torrefaction of biomass waste with LDPE resulted in higher char yield, as well as higher energy content.…”

“…This lower ash content can act as a catalyst for the pyrolysis treatment to promote secondary reactions of volatile decomposition and char formation [ 35 ]. The volatile matter for the residues of these MFPWs was higher than the value found by other residues of plastic waste [ 41 ]. Thus, these MFPWs could have a relevant potential in energy generation with little variation due to changes in chemical composition and amount of aluminum in each sample.…”

Modeling of Metalized Food Packaging Plastics Pyrolysis Kinetics Using an Independent Parallel Reactions Kinetic Model

Recently, a pyrolysis process has been adapted as an emerging technology to convert metalized food packaging plastics waste (MFPWs) into energy products with a high economic benefit. In order to upscale this technology, the knowledge of the pyrolysis kinetic of MFPWs is needed and studying these parameters using free methods is not sufficient to describe the last stages of pyrolysis. For a better understanding of MFPWs pyrolysis kinetics, independent parallel reactions (IPR) kinetic model and its modification model (MIPR) were used in the present research to describe the kinetic parameters of MFPWs pyrolysis at different heating rates (5–30 °C min−1). The IPR and MIPR models were built according to thermogravimetric (TG)-Fourier-transform infrared spectroscopy (FTIR)-gas chromatography−mass spectrometry (GC-MS) results of three different types of MFPWs (coffee, chips, and chocolate) and their mixture. The accuracy of the developed kinetic models was evaluated by comparing the conformity of the DTG experimental results to the data calculated using IPR and MIPR models. The results showed that the dependence of the pre-exponential factor on the heating rate (as in the case of MIPR model) led to better conformity results with high predictability of kinetic parameters with an average deviation of 2.35% (with an improvement of 73%, when compared to the IPR model). Additionally, the values of activation energy and pre-exponential factor were calculated using the MIPR model and estimated at 294 kJ mol−1 and 5.77 × 1017 kJ mol−1 (for the mixed MFPW sample), respectively. Finally, GC-MS results illustrated that pentane (13.8%) and 2,4-dimethyl-1-heptene isopropylcyclobutane (44.31%) represent the main compounds in the released volatile products at the maximum decomposition temperature.

“…Thus, carbonization provides excellent resource recovery as well as environmental protection and is suitable for most plastics as the pre-treatment process is very simple, and the carbonized products are valuable and tailorable. Rago et al performed carbonization of mixed solid wastes with LDPE at ~ 300 °C for ~ 30 min, which resulted in higher char yield and energy content (Rago et al 2020 ). Similarly, Hanoglu et al investigated the carbonization of textile fibers with PEs and acrylic at ~ 300–400 °C and reported the role of temperature in defining the solid product (Hanoğlu et al 2019 ).…”

Graphical abstract The unforeseen outbreak of the COVID-19 epidemic has significantly stipulated the use of plastics to minimize the exposure and spread of the novel coronavirus. With the onset of the vaccination drive, the issue draws even more attention due to additional demand for vaccine packaging, transport, disposable syringes, and other allied devices scaling up to many million tonnes of plastic. Plastic materials in personal protective equipment (PPE), disposable pharmaceutical devices, and packaging for e-commerce facilities are perceived to be a lifesaver for the frontline healthcare personnel and the general public amidst recurring waves of the pandemic. However, the same material poses a threat as an evil environmental polluter when attributed to its indiscriminate and improper littering as well as mismanagement. The review not only highlights the environmental consequences due to the excessive use of disposable plastics amidst COVID-19 but also recommends mixed approaches to its management by adopting the combined and step-by-step methodology of adequate segregation, sterilization, sanitization activities, technological intervention, and process optimization measures. The overview finally concludes with some crucial way-forward measures and recommendations like the development of bioplastics and focusing on biodegradable/bio-compostable material alternatives to holistically deal with future pandemics.
