This study applied pyrolysis with unique low pyrolytic temperatures to convert disinfected PP-based isolation gown waste (PP-IG) into an optimised quantity of char yields. A batch reactor using a horizontal furnace was used to mediate the thermal decomposition of PP-IG. Enhanced surface location and porosity value of PP-IG derived char were obtained through an optimised slow pyrolysis approach. The outcomes showed that the quantity of yielded char was inversely proportional to the temperature. This method relied heavily around the process parameters, specifically pyrolytic temperature. In addition, because the heating price decreased, at the same time as longer isothermal residence time, the char yields had been elevated. Optimised temperature for maximum char yields was recorded. The enhanced SBET values for the char and its pore volume were collected, 24 m2 g-1 and 0.08 cm3 g-1 , respectively. The char obtained at greater temperatures show larger volatilisation and carbonisation. These findings are useful for the utilisation of this pyrolysis model in plastic waste management and conversion of PP-IG waste into char for further activated carbon and fuel briquettes applications, using the enhanced char yields, amidst the COVID-19 pandemic.

Introduction Severe acute respiratory syndrome coronavirus (SARS-CoV-2 or COVID-19 virus) pandemic attacked the globe vigorously in the fourth quarter of 2019 till the present. Thus, the Planet Overall health Organization (WHO) [1] announced a public overall health emergency because of the outbreak on 30 January 2020. As reported on 7 February 2021, there were 106 million active COVID-19 instances, with 2.three million deaths calculated from 219 nations and regions impacted by the international outbreak [2]. Environmental pollution is one of the most worrying consequences because of this COVID-19 epidemic. As of 22 November 2020, a huge amount of COVID-19 medical waste (C.
