Abstract

To prevent the transmission of COVID-19, the World Health Organization recommends the implementation of health protocols including using disposable masks. The use of disposable face masks has an impact on the emergence of mask waste in aquatic environments which results in pollution of water sources by microfibers. Degradation by indigenous microorganisms can be one of the solutions for handling waste that is environmentally friendly and cost effective. In this study, bacteria were isolated from the coast of Lampung Bay which was polluted with plastic waste and masks. Bacterial isolates were characterized by morphological and biochemical tests before the selected one being used for degradation. After seven days of incubation, gravimetric analysis showed that the mask pieces increased in weight when compared to the control. However, the degradation process can be shown by the results of Scanning Electron Microscope (SEM) analysis which shows damage in the form of holes on the surface of the mask when compared to the new mask and the control. SEM images also showed the presence of bacterial biomass remnants attached to the surface of the mask. Based on the results of this study, Lampung Bay indigenous microorganism isolate showed potential as a degrader of disposable face masks.

Abstract

The use of disposable face masks during the Covid-19 pandemic has resulted in the emergence of mask waste polluting aquatic environments due to poor management. This waste will decompose into microfibers which accumulate in aquatic organisms. The combination of vermiremediation with the addition of degrading microorganisms can be one of the solutions for treating disposable mask waste. In this study, Eudrilus eugeniae, an earthworm species, was used in vermiremediation with variations in the treatment by adding indigenous bacterial isolate from the waters of Lampung Bay which has been proven able to degrade disposable masks. The results showed that the vermiremediation technique can be used to degrade disposable masks, indicated by a decrease in mask weight after incubation for two months in the amount of 0.03 grams and 0.05 grams for the treatment with the Eudrilus eugeniae and a combination of bacterial isolate respectively against the initial weight. Lampung Bay indigenous bacterial isolate helped accelerate the mask degradation process in the combined vermiremediation technique. The carbon, nitrogen, phosphorus, and potassium contents of the compost produced by the vermiremediation process have met the SNI for compost from domestic organic waste.
