The outbreak of COVID virus resulted not only in massive human deaths but also created huge waste disposal issues. Proper disposal of COVID waste is necessary. The conversion of these wastes into value‐added products such as syngas is beneficial to overcome energy scarcity issues. The Indian high ash coal (HAC) is nonreactive, and the co‐utilisation of HAC with these plastic wastes is advantageous to produce high‐quality syngas. In the present study, thermal treatment of overall gowns (OG) used during COVID by pyrolysis and gasification process was carried out under inert and reactive conditions with and without HAC at various operating temperatures. During pyrolysis, oil with a yield of 17% was produced under N2 conditions at 900°C, whereas a reduced oxygen content in the oil was observed (absence of C–O) under CO2 conditions. The co‐gasification of OG with high ash coal in the fuel mixture resulted in the heating value of syngas as high as 8.56 MJ nm−3. The calorific value of the syngas increases by 51.8% when OG content in the fuel mixture is increased to 20% because hydrocarbon content in syngas increases by 8.73 times. Thermogravimetric analysis showed that by adding OG, gasification initiated 35°C earlier as compared to HAC. The solid residue obtained by co‐gasification contains calcium in the form of CaO and CaCO3 due to COVID‐19 waste. The global warming potential of the syngas generated is reduced by 32% with the addition of OG to 20%.

In this study, the thermal behaviours of Cannabis sativa (CS), coal and their five different blends at a heating rate (β) of 10, 20, 30, 40 and 50°C min−1; the synergistic effects between CS and coal; and the distribution of gases formed during pyrolysis and combustion were investigated by using the thermogravimetric analysis/Fourier transform infrared spectrometer (TGA/FTIR) integrated system. The TG and DTG curves showed that the thermal decomposition of pyrolysis and combustion of all feedstocks at all β values had three main decomposition stages. The synergistic effect was observed for DTGmax, mass loss (ML), or final residue (FR) at least once at a given β of each blend; and the synergy was more effective for DTGmax and ML in pyrolysis than in combustion, whereas the opposite was true for FR. The lowest emissions of CO2, CH4, NO x and SO2 except CO during pyrolysis occurred at the blend of 0% CS + 100% Coal. However, the highest emissions of CO, CH4, NO x and SO2 except CO2 during combustion were observed at the blend of 80% CS + 20% Coal. The emissions of CO, CO2, NO x and SO2 from all samples during pyrolysis were lower than that of combustion, indicating that pyrolysis can be preferred due to its lower emission to the environment. Different structural properties of CS, coal and their blends caused different thermal behaviours, synergistic effects and gas products during pyrolysis and combustion by TGA/FTIR, suggesting detailed further investigation for upper-scale pyrolysis and combustion applications.
