Covid-19 effects on municipal solid waste management: What can effectively be done in the Brazilian scenario?

•Covid-19 pandemic is increasing municipal solid waste generation.•Infectious waste from households requires additional planning by the municipalities.•Waste management demands hygiene routines, use of PPE, segregation and packing.•Municipalities with poor waste management face difficulties in adopting measures. The Covid-19 pandemic will leave a lasting impact on nearly every aspect of life in society and has also raised concerns on the contamination risks associated with waste management. This study presents a review on the main recommendations related to the management of municipal solid wastes during the pandemic. The recommendations were classified according to the target audience, and their applicability to the Brazilian reality is discussed. Results show that most analyzed recommendations are related to hygiene routines, use of personal protective equipment, and proper segregation, packing and final destination of potentially contaminated wastes. Brazilian organizations show a special concern about the exposure risks of waste pickers, advising for the temporary suspension of manual waste collection and sorting, hygiene protocols, social distancing and quarantine of recyclable materials. Overall, the recommendations are highly dependent on awareness and engagement of citizens and on planning and support of municipalities, which must invest in information campaigns and provide alternatives for the infectious waste produced in households. Furthermore, this study points out that the recommendations were issued in an emergency scenario, but as the pandemic is expected to last for an extended period of time, they must be revised as local contexts change, seeking to maintain and extend citizens engagement in selective collection and even in actions towards waste reduction.
