The daily use of facemask to prevent virus transmission increases the negative effect on the environment because of improper waste disposal. Due to the absence of baseline data, the impact of facemask and medical waste generation, as well as the community’s management practice, should be studied to avoid further environmental degradation. In this study, we surveyed 384 respondents and conducted computational analysis to provide an overview of the household’s facemask usage and ecological footprint in combating Covid-19. Results showed that most respondents (48.7%) use two facemasks per day. Thus, an estimated 417,834 facemasks are disposed daily, generating 3,585 kg/day of additional waste. The average medical waste of Covid-infected individuals is 3.29 kg per day per capita. This yields 22,438 kg. of CO 2 eq., which could contribute to the global warming potential; however, there is also a potential recovery of 61.572 gigajoules of energy for power generation. Most respondents are aware of proper facemask waste management practices, but some lacks application regarding responsible waste disposal. Despite the contribution of facemask to the overall solid waste generation, the city’s current management remains a challenge since disposable facemasks are potentially mixed with other types of waste from its storage, collection, and disposal.

“…methane (anaerobic) digestion, biodrying and/or biostabilization [3,4]. Biological processing of the UFMSW is mainly conducted using anaerobic [5][6][7] and aerobic biostabilization [8][9][10] resulting in limited sanitation (decreased microbial activity) as well as reduction of waste mass and volume and organic matter (OM) content.…”

The main goal of this work was to analyze the impact of biochar addition and changes in air-flow rates on the intensive phase of aerobic biostabilization of undersized fraction of municipal solid waste (UFMSW). The novelty of this paper stems from the use of biochar to shorten the process and generate “well-stabilized waste”. The following six different input mixtures were tested (without biochar and with the addition of biochar at: 1.5%, 3%, 5%, 10% and 20%), at three different air-flow rates: 0.1, 0.2 and 0.4 m3·d−1·(kg org DM)−1. It was found that the biochar addition of more than 3 wt% causes water accumulation in the treated waste, but does not allow for reducing organic matter (OM) content below 35% DM, nor OMloss values below 40% (the exception is the 5 wt% addition of biochar at the air-flow rate of 0.2 m3·d−1·(kg org DM)−1). Moreover, 10 wt% and 20 wt% biochar additions to UFMSW intensify the increase in microbial abundance, which may result in higher oxygen demand or development of anaerobic zones. The most favorable biochar doses in terms of final UFMSW sanitization are 3 wt% and 5 wt%.
