“…Around COVID waste, for example, thermo-catalytic pyrolysis using a new 3-layer pre-dissolved face mask catalyst has been studied to extract from different types of plastic waste, obtaining the pyrolytic oil of waste masks, gloves, and other PPE kits possess. A similar study showed that the pyrolysis liquid had a high amount of alkanes and alkenes and a higher concentration of mixed aromatics [ 22 ]. Some oxygen-containing compounds were also observed in the derivatized sample, such as cyclohexane, cyclooctane, 1-methyl-3-propyl, etc.…”

“…2023, 13, x FOR PEER REVIEW 3 of 19 recently, Wang et al [13] have analyzed the applicability of the hydropyrolysis and hydrocracking processes to convert face masks into fuel-range iso-alkanes using Ru/C as a catalyst. Ramalingam et al [33] examined the thermal pyrolysis of different medical waste including face masks, gloves, and other PPE waste with a special emphasis on the characteristics of the obtained liquid product. The authors concluded that the fuel properties of the liquid product from pyrolysis of face masks, gloves, and other PPE waste were closer to diesel fuel.…”

This research aims to develop a new strategy to valorize wasted COVID-19 masks based on chemical recycling by pyrolysis to convert them into useful products. First, surgical and filtering face piece masks, as defined in Europe by the EN 149 standard (FFP2), were thermally pyrolyzed at temperatures of 450, 500, and 550 °C, and the yields of valuable solid (biochar), liquid (biooil), and syngas products and their characteristics were determined. At low temperatures, biochar formation was favored over biooil and syngas production, while at high temperatures the syngas product yield was enhanced. The highest yield of biooil was found at a pyrolysis temperature of 500 °C, with both surgical and FFP2 masks achieving biooil yields of 59.08% and 58.86%, respectively. Then, the pyrolysis experiments were performed at 500 °C in a two-stage pyrolysis catalytic reactor using sepiolite as a catalyst. Sepiolite was characterized using nitrogen adsorption–desorption isotherms and Fourier-transform infrared spectroscopy. Results showed that the two-stage process increased the final yield of syngas product (43.89% against 39.52% for surgical masks and 50.53% against 39.41% for FFP2 masks). Furthermore, the composition of the biooils significantly changed, increasing the amount of 2,4-Dimethyl-1-heptene and other olefins, such as 3-Eicosene, (E)-, and 5-Eicosene, (E)-. Additionally, the methane and carbon dioxide content of the syngas product also increased in the two-stage experiments. Ultimately, the effect of sepiolite regeneration for its use in consecutive pyrolysis tests was examined. Characterization data showed that, the higher the use-regeneration of sepiolite, the higher the modification of textural properties, with mainly higher changes in its pore volume. The results indicated that the pyrolysis of face masks can be a good source of valuable products (especially from biooil and syngas products).

Waste mask has been subjected to catalytic pyrolysis. Fly ash used as catalyst. Biogas, formed by the degradation of food waste, is used as the heating agent. Optimum conditions for pyrolysis were determined by the TGA and DTA analysis of the mask. Waste mask was completely converted into oil and gaseous products. The fraction after distillation is the high boiling fraction. By this, the physical properties of both fractions have been determined using standard methods. The physical characteristics of both the low and high boiling fractions are almost very similar to that of petrol and diesel respectively. Both fractions were subjected recorded analysis the GCMS. 1H ,13C NMR and IR spectra were recorded for both fractions. Elemental analysis was carried out for the mask and both oil fractions. GCMS analysis shows that the low boiling fraction contains thirteen 1-alkenes with 8–12 carbon atoms and three alcohols without a C = C bond. The high boiling fraction was found to contain nine isomeric alkenes with 12 carbon atoms. This fraction was found to also contain seven alcohols without C = C bond. NMR, IR spectra and elemental analysis are in support of this composition.
