“…As seen in Table 4, water absorption of GPs increased with the increasing DMMs content, which was consistent with the research results from Castellote et al, 32 Ahmed and Lim, 23 and Avudaiappan et al 27 for DMM-reinforced concrete. On the contrary, Kilmartin-Lynch et al, 16 Miah et al, 25 and Aal et al 33 found that the increasing DMMs content led to a greater decrease in the water absorption of the concrete.…”

“…20 Consequently, some attempts have been made to use DMMs as an additive or a substitute for aggregate in cement or concrete. The enhanced effect and various contributions of DMMs have been verified by many studies, 16,17,[21][22][23][24][25][26][27][28] providing an effective and environmental-friendly method to solve the challenge of treating waste DMMs.…”

A tremendous amount of the nonbiodegradable microplastic waste has been generated after the outbreak of COVID‐19 by the widespread use of single‐use personal protective equipment, especially disposable medical masks (DMMs). This has caused harm to the health and safety of human beings and various organisms. Finding a way to properly deal with these single‐use medical wastes has become an urgent problem. In this paper, an innovative way was explored to use DMMs in geopolymer (GP). The physical properties, mechanical strength, and resistance to high temperatures (200–800°C) of the composites were investigated. The findings of the study revealed that DMMs had negligible influence on resistance to high temperatures, but showed a positive influence on enhancing the compressive and flexural strengths of GPs at ambient temperature. The optimum DMMs content was 0.4 wt%, at which the compressive and flexural strengths of the GP composites were enhanced by 5.8% and 22.68% compared with the pure GP, respectively. The same polypropylene (PP) fiber amount increased compressive and flexural strengths by 7.49% and 9.76%, respectively. This thus confirmed that DMMs can be sustainably utilized in green building materials, playing a role as PP fibers toughening and contributing to the effective management of waste plastics.

“…The growth in Single use plastic (SUP) such as gloves, face masks, face shields, PPE kits has added pressure on authoriites to manage the waste efficiently (Patrício Silva et al, 2020). To address this concern, efforts need to be made to find innovative ways of recycling and reusing masks (Figure 5) in order to reduce the burden on landfills (Ahmed and Lim, 2022;Idrees et al, 2022). There should be a mechanism developed for incentivizing and giving rewards to people developing such methods.…”

Proper management of Biomedical Waste (BMW) is an essential component of any sustainable healthcare sector. With the burst of COVID-19 pandemic when every hospital and treatment facility was overburdened patients, efficient handling of the huge amount of generated BMW became a task for the entire world. This review compares the BMW generated before and during the second wave of COVID-19, highlights the challenges in managing the exuberated amount of COVID-19 waste and sites recommendations to promote sustainable design thinking, in order to address this grave concern in the current setting of the Indian system. The study indicated that inappropriate management of waste and the lacunae in the entire chain from segregation to collection until its disposal has posed a serious threat to the wellbeing of healthcare workers, sanitation staff as well as the operators and housekeeping staff at the hospitals, isolation centers and Municipal Corporation. Many states had inadequate number of common BMW treatment facilities (CBMWTFs) leading to inefficient treatment of the excess waste. The behavioural and attitudinal barriers of neglect and ignorance of different stakeholders further aggravated the problem of BMW management to manifolds. To achieve better management we recommend spreading awareness regarding the kind and infectious nature of waste generated by COVID-19 patients and their caregivers, segregation and decontamination of such waste at source and increasing the capacity as well as number of CBMWTFs. Creative ways to recycle the waste must be devised so as to reduce the burden on disposal sites.

“…On the other hand a discernible increase in the usage and manufacture of face masks has been reported worldwide since the COVID-19 pandemic emerged. The global market for disposable masks has expanded from $0.73 billion to $22 billion annually due to governments mandating the wearing of face masks in public places [ [12] , [13] , [14] , [15] ]. The enormous use of face masks has drawn attention recently due to waste generation, which endangers the environment as it is used a million times each day globally and requires more energy and raw materials to manufacture [ 13 , [16] , [17] , [18] ].…”
