Brazil is the fourth largest producer of plastic waste in the world. Among all the challenges the country had faced in the development of public policies for the banning of single-use plastics, the new coronavirus pandemic scenario determined the suspension of these laws indefinitely. In 2020, Brazil became the global epicenter of COVID-19. This scenario changed the habit and behavior of Brazilian consumers, who increased the consumption of plastics due to their importance in applications as protective material. The country also has social problems related to waste management that depend mainly on waste pickers. These workers need social visibility and protection not only to face the current health crisis but also to guarantee their income and survival. This work aims to discuss the increase in single-use plastics that are not intended for recycling and the respective environmental, economic, and social impacts for the country. We demonstrate the lack of data on waste management in Brazil and highlight the importance of the social inclusion of waste pickers for a circular economy. Especially after the change of scenario with the COVID-19 pandemic, the country must have adequate planning and improvements in waste management, recycling programs, and political intervention to raising awareness among the population and guaranteeing social rights for waste pickers.

“…This way, the medical and domestic fractions of the Covid-induced solid wastes produced globally are posing an ugly threat to the environment. This biohazard-laden plastic waste must be treated through a green route to free the environment from this burden in an eco-friendly manner and abiding by the global agenda of circular economy to contribute to sustainable waste management practices [19].…”

Since the end of 2019, COVID-19 pandemic has affected 220 countries and currently majority of the world is facing the wrath of the second wave. One of the outcomes of the ongoing pandemic is the generation of huge amount of solid polymeric “COVID-waste” comprising medical waste, personal protective equipment (PPE) waste, packaging waste, and other household waste with potential infectious components residing on it. Thermochemical route is the preferred treatment and effective way of disposal of such infectious polymeric waste. Typically, incineration is employed to ensure complete destruction of the pathogens which is not a resource-efficient method. Pyrolysis is a sustainable alternative which can handle the present COVID-waste stream in short-term and long-term yielding valuable fuel and material products. Recently published literature in this avenue have clearly shown the versatility of this technology in efficiently handling both mono and mixed stream of polymers. Based on facts, we propose a resource resurgence framework that utilizes pyrolysis as the core conversion route for effectively handling COVID-waste streams. Our framework suggests how these plants can be operational and helpful in generation of revenue in post-pandemic times as well. We expect that the conscientious adoption of pyrolysis will certainly lead us towards a circular economy paradigm.

“…It benefits from still usable resources and reduces the quantity of waste that needs to be treated and or/disposed of [7]. Recycling is also another option referring to the collection and reuse of waste materials [41]. Valuable materials can be recycled when their components cannot be maintained, resold, or remanufactured economically anymore.…”

The importance of the circular economy has greatly increased in the past few years, and consequently, the interest in the circular economy as a research field has also increased, which led to an exponential growth in the number of literature reviews on the subject with different purposes. In order to analyze the topics that have been studied and assess the quality of these secondary reviews, this study carried out a tertiary literature review on the subject. This study identified the literature reviews on the circular economy, the most frequently cited papers, and the main research topics in the field. We have also analyzed the types of research questions that have been proposed by secondary studies. Finally, we evaluated the extent to which secondary reviews have assessed the quality of primary studies. We found out that literature reviews on the circular economy are frequently related to the areas of supply chain and technology. We also concluded that there is a need for designing research questions that explore more complex relationships, since most questions are descriptive or process-related. Some research questions are proposed to guide future studies. We also observed that secondary studies have failed to appropriately assess the quality of primary studies.
