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.

Covid-19 大流行将对社会生活的几乎各个方面产生持久影响，并引发人们对废物管理相关污染风险的担忧。本研究回顾了大流行期间与城市固体废物管理相关的主要建议。这些建议根据目标受众进行了分类，并讨论了它们对巴西现实的适用性。结果显示，大多数分析建议都与卫生习惯、个人防护设备的使用以及潜在污染废物的正确隔离、包装和最终目的地有关。巴西组织对垃圾捡拾者的暴露风险表示特别关注，建议暂时停止手动垃圾收集和分类、卫生协议、社交距离和可回收材料的检疫。总体而言，这些建议在很大程度上取决于公民的认识和参与以及市政当局的规划和支持，市政当局必须投资于信息宣传活动并为家庭产生的传染性废物提供替代品。此外，本研究指出，这些建议是在紧急情况下发布的，但由于疫情预计将持续较长时间，因此必须根据当地情况的变化进行修订，力求维持和扩大公民选择性收集的参与甚至是减少废物的行动。
