“…In developed economies this may mean increased raw material for recycling plants whilst for developing countries temptations will be high to dispose of the waste into the surrounding environment increasing the amount of mismanaged waste. Studies have begun documenting this unique period with works from [162][163][164][165][166][167]. In the near future more studies on quantities, implications and trends of generated plastic waste quantities will be documented.…”

Over the years, the world was not paying strict attention to the impact of rapid growth in plastic use. This has led to unprecedented amounts of mixed types of plastic waste entering the environment unmanaged. Packaging plastics account for half of the global total plastic waste. This paper seeks to give an overview of the use, disposal, and regulation of food packaging plastics. Demand for food packaging is on the rise as a result of increasing global demand for food due to population growth. Most of the food packaging are used on-the-go and are single use plastics that are disposed of within a short space of time. The bulk of this plastic waste has found its way into the environment contaminating land, water and the food chain. The food industry is encouraged to reduce, reuse and recycle packaging materials. A wholistic approach to waste management will need to involve all stakeholders working to achieve a circular economy. A robust approach to prevent pollution today rather than handling the waste in the future should be adopted especially in Africa where there is high population growth.

“…Yang et al discussed the medical waste disposal measures employed in Wuhan and analyzed the benefits and drawbacks of different measures, suggesting that stationary facilities and municipal incinerators were preferred for medical waste disposal ( Yang et al, 2021 ). Sharma et al argued that the crisis caused by the COVID-19 pandemic has altered the dynamics of global waste production, and unexpected fluctuations in waste composition and quantities require a dynamic response from policymakers to address gaps in the system ( Mohammad et al, 2021 ; Neumeyer et al, 2020 ; Sharma et al, 2020 ). Previous research has primarily targeted the technologies and strategies employed for medical waste disposal during pandemics, but there has been little research on medical waste disposal during major public health emergencies and the impact of pandemics on medical waste management systems due to the lack of data.…”

The global pandemic caused by the 2019 coronavirus (COVID-19) has led to a dramatic increase in medical waste worldwide. This tremendous increase in medical waste is an important transmission medium for the virus and thus poses new and serious challenges to urban medical waste management. This study investigates the response of medical waste management to the COVID-19 pandemic and subsequent changes in Wuhan City based on the most detailed data available, including waste generation, storage, transportation, and disposal. The results show that despite a 5-fold increase in the demand for daily medical waste disposal in the peak period, the quick responses in the storage, transportation, and disposal sectors during the pandemic ensured that all medical waste was disposed of within 24 hours of generation. Furthermore, this paper discusses medical waste management during future emergencies in Wuhan. The ability of the medical waste management system in Wuhan to successfully cope with the rapid increase in medical waste caused by major public health emergencies has important implications for other cities suffering from the pandemic and demonstrates the need to establish resilient medical emergency systems in urban areas.

“…The chemical and thermal methods are used as main processors to produce raw materials or energy products. In case of this type of waste, treatments by heat are preferred to eliminate the virus and convert cotton into oil and gas [ [26] , [27] , [28] ]. Also, the pyrolysis process is classified as an eco-friendly approach with less emission and it may be addressed to the shortage of landfills and incineration disposal [ 29 ], where the medical waste can be converted into homogeneous energy products with high values in nitrogen atmosphere without need for pre-treatment in safe ambient [ 30 ].…”

In the times of Covid-19, face masks are considered to be the main source of protection against the virus that reduces its spread. These masks are classified as single-use medical products with a very short service life, estimated at few days, hence millions of contaminated masks are generated daily in the form of hazardous materials, what requires to develop a safe method to dispose of them, especially since some of them are loaded with viruses. 3-ply face masks (3PFM) represent the major fraction of this waste and are composed mainly from polypropylene and melt blown filter with high content of volatile substances (96.6 wt.%), what makes pyrolysis treatment an emerging technology that could be used to dispose of face masks and convert them into energy products. In this context, this work aims to study pyrolysis kinetic behaviour and TG-FTIR-GC–MS analysis of 3PFM. The research started with analysis of 3PFM using elemental analysis, proximate analysis, and compositional analyses. Afterwards, TG-FTIR system was used to study the thermal and chemical decomposition of 3PFM analyzed at different heating rates: 5, 10, 15, 20, 25, and 30 °C/min. The GC/MS system was used to observe the synthesized volatile products at the maximum decomposition temperatures. After that, isoconversional methods, the advanced nonlinear integral isoconversional method, and the iterative linear integral isoconversional method were used to determine the activation energies of mask pyrolysis, while the distributed activation energy model and the independent parallel reactions kinetic model were used to fit TGA and DTG curves with deviations below <1. The TGA-DTG results showed that 3PFM can decompose in three different periods with a total weight loss of 95 % and maximum decomposition in the range 405−510 °C, while the FTIR spectra and GC–MS analysis exhibited that – C—H (aromatic and aliphatic) and 2,4-Dimethyl-1-heptene (28–43 % based on heating rate) represented the major compounds in the released volatile components. Finally, Vyazovkin and the iterative linear integral isoconversional methods gave activation energies almost similar to that obtained by the KAS isoconversional method.
