“…Municipal solid waste (MSW) is an unavoidable by-product of human activity, and its recycling and recovery can facilitate the progression of a circular economy (Das et al 2021 ). However, the COVID-19 pandemic has brought MSW systems severe challenges, such as the quantity variation and composition change of MSW (Vaverková et al 2020 ; Vu et al 2021 ; Yousefi et al 2021 ). For instance, a significant escalation of medical waste was observed in some Asian cities and countries, such as India, during the lockdown compared to levels before the pandemic (Somani et al 2020 ; You et al 2020 ; Zand and Heir 2020 ).…”

The COVID-19 pandemic has induced many issues for all societal sectors, in particular in the production and disposal of municipal solid waste. This may be because successive easing and reimposing of lockdown measures have deeply changed people’s movements, consumers’ behaviors and waste management. Previous studies have focused on the short-term effects of lockdowns on waste changes, yet there is little knowledge on waste variations during successive lockdowns and unlocking of various lockdown intensities. Moreover, the efficiency of lockdown and its relation to people’s mobility in different countries are still not clear. Here, we studied the variations of amount and composition of municipal solid waste before the pandemic in 2019 and during the pandemic in 2020–2021 in USA, Brazil, Canada, UK, France and Italy. We used a stringency index and a composite mobility index to assess the lockdown intensity and people’s movements. Results show that the mobility index sharply decreased with lockdown intensity, and enforcing measures were more efficient in France and Italy. Compared to 2019, prolonged lockdowns caused larger decreases in the quantity of commercial and construction wastes versus household waste. The initial implementation of lockdown or unlocking measures promoted inhabitants’ consumption, generally leading to the increased waste amount, by about 9% for Trento and 12% for Montreal at the beginning of lockdown, respectively. Moreover, larger variations in the waste amount in Trento, from − 25.3 to 9.8%, were in line with higher lockdown intensity compared to those in Montreal, from − 9.5 to 12.7%, affected by people’s mobility, consumers’ behaviors and waste management.

“…The global spread of the SARS-CoV-2 virus and the resulting COVID-19 pandemic have introduced new challenges to solid waste management that require prompt responses from policy makers and waste researchers (Purnomo et al, 2021;Richter et al, 2021b;Vu et al, 2021b). These challenges relate to the significant increase in personal protective equipment (PPE) and COVID-19-related medical wastes and hazardous materials (Hantoko et al, 2021;Torres and De-la-Torre 2021;Valizadeh et al, 2021).…”

In this study, the hospital waste generation rates and compositions in Delhi were examined temporally and spatially during the first COVID-19 wave of April 2020. A total of 11 representative hospitals located in five districts were considered. The pre-COVID hospital waste generation rates were relatively consistent among the districts, ranging from 15 to 23 tonne/ month. It is found that the number of hospital beds per capita may not be a significant factor in the hospital waste quantity. Strong seasonal variations were not observed. All districts experienced a drastic decrease in generation rates during the 1-month lockdown. The average rates during the COVID period ranged from 12 to 24 tonne/month. Bio-contaminated and disposable medical product wastes were the most common waste in Delhi's hospitals, representing 70-80% by weight. The changes in waste composition were however not spatially consistent. The lockdown appeared to have had a higher impact on hospital waste generation rate than on waste composition. The findings are important as the design and operation of a waste management system are sensitive to both waste quantity and quality. Waste records at source helped to minimize waste data uncertainties and allowed a closer examination of generation trends.

“…As a response to the urgent call for action against adverse effects of the pandemic, many COVID-related studies have been conducted within various domains and disciplines. In this regard, a massive amount of research has also been conducted focusing on the effects of the pandemic on WM systems, practices, and different waste streams, such as healthcare WM challenges (de Aguiar Hugo and Lima, 2021), household food waste ( Amicarelli and Bux, 2021 , Vittuari et al, 2021 ), effective plastic WM during and post pandemic ( Vanapalli et al, 2021 ), solid waste and environmental impacts ( Urban and Nakada, 2021 ), municipal waste disposal behavior ( Vu et al, 2021 ), face mask waste generation ( Torres and De-la-Torre, 2021 ), reusing COVID-19 face mask as a novel solution to the emerging COVID-19 waste issue (Rehman and Khalid, 2021), solid waste generation and management strategies ( Liang et al, 2021 ), single-use plastic waste (Leal Filho et al, 2021 ), behavioral impacts on residential food provisioning, use, and waste (Babbitt et al, 2021a), perceptions of people towards household waste management in the wake of the pandemic ( Acharya et al, 2021 ), municipal solid waste management ( Yousefi et al, 2021 ), waste production in households ( Filho et al, 2021 ), and enabling circular economy model in solid waste management as a recovery plan post COVID-19 ( Sharma et al, 2021 ).…”
