“…They are mainly disposed of by incineration and landfilling in municipal solid waste. Incineration of plastics may cause the release of hazardous gases such as dioxins, hydrogen chloride, and nitrous oxide, with consequent environmental impacts [65][66][67]. That is why the sustainability of WPB recycling along with sustainability in the whole pharmaceutical industry sector has become an environmental, social, and economic concern almost everywhere [68][69][70].…”

“…Another separation approach for waste packaging is the application of switchable hydrophilicity solvents that are separated from the extracted product by changing their polarity, upon the addition and removal of CO 2 . Others applied N,Ndimethylcyclohexylamine (DMCHA) to separate polymer and aluminum layers from packaging materials [67,72].…”

Circular Economy in Conjunction with Treatment Methodologies in the Biomedical and Dental Waste Sectors

In this review, life cycle assessment (LCA) principles are coupled with circular economy (CE) in order to address LCA examples in the biomedical sector worldwide. The objectives were (1) to explore the application of LCA in the medical, pharmaceutical, and dental fields; (2) to describe the ways of biomedical waste management; (3) to emphasize on the problem of dental waste in private and public dental sectors; and (4) to propose ways of "green circulation" of the dental waste. A literature search was performed using the Google Scholar, PubMed, and Scopus search engines covering the period from January 2000 until May 2020, corresponding to articles investigating the LCA and circular economy principles and legislation for biomedical and dental waste, their management options, and modern ways of recycling. The results showed that incineration seems to be the best management way option involved despite the mentioned drawbacks in this technology. Different adopted models are well defined for the dental field based on the 3Rs' module (reduce, reuse, recycle). Replacing disposable products with reusable ones seems to be a good way to tackle the problem of waste in medical and dental sectors. Interventions on the selection and better biomedical and dental waste management will ensure eco-medicine and eco-dentistry of the future. These new terms should be the new philosophies that will change the way these fields operate in the future for the benefit of the professionals/patients and the community.

“…Based on the results obtained by Mumladze et al (2018), MFPWs contain more than three pseudocomponents, including dye layer (pigments and organic component), various plastic films (like PE, PP, PVC, PS, PET, etc. ), and a metallic layer (Al) [ 7 , 23 ]. As observed in the DTG curves in Section 3.2 , the curves consist of two visible peaks resulting from simultaneously decomposed pseudocomponents in two forms, the organic part in dye layers and sealing and plastic films [ 48 ], while Al layer cannot decompose due to its high melting temperature > 800 °C.…”

“…joined mechanically and chemically by air emptying [ 2 , 3 ], this improves their performance and addresses such environmental factors as moisture and sunlight [ 4 ]. According to the life cycle evaluation of MFPWs that was conducted by many studies [ 5 , 6 ], once it ends its very short service period, which is estimated for a few days, it is difficult and not profitable to separate these layers and to recover them in the shape of secondary raw materials using the traditional mechanical and chemical practices such as grinding and dissolution treatment [ 3 , 7 , 8 ]. Additionally, these studies demonstrated clearly that the separation of MFPWs layers is always a great challenge as the surface area of the thinner materials is higher in comparison to the bulk material and it is exposed more to the atmospheric oxygen [ 9 ], thus MFPWs mostly end in landfilling, followed by incineration with other municipal solid waste, and the rate of recycling is almost negligible, being around~20% [ 10 , 11 ].…”

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.
