Abstract
This article aims to describe the current state of research on plastic waste management as a circular economy practice at the end of the supply chain. The methodological strategy chosen was a systematic literature review. The articles selected from the Web of Science and Scopus databases were screened, and the research corpus consisted of 201 articles published in journals between 2014 and 2021. The results present 13 study categories, showing topics such as pyrolysis, business models, Industry 4.0, and energy generation. The insertion of Industry 4.0 technologies is still in its initial stages, comprising mainly the generation of inputs to reuse waste for 3D printers’ materials. Regarding energy generation, the insertion of processes such as pyrolysis for fuel generation stands out. The proposed discussion in this article suggests a circular ecosystem in which wastes follow a reuse flow according to their properties; incineration can be an option depending on the stage and benefits generated from the removal of plastic waste from the ecosystem. The highlighted issue is the scalability of the developed processes in the research, which is only possible if the state, universities, and civil society integrate efforts in the construction of a circular ecosystem infrastructure for waste management.
Highlights
Concerning generated waste, it is estimated that each person produces an average of 1.3 kg of solid waste per day
This being the case, the opportunity arises to discuss the adoption of a circular economy perspective [5,6], this one being aimed at processes that link industrial ecology to waste management [7,8]
The first phase was determined by the question that guides this research: “How is plastic waste management presented in research that contemplate the circular economy at the end of the supply chain?” the Web of Science and Scopus databases were used as the research sources
Summary
Concerning generated waste, it is estimated that each person produces an average of 1.3 kg of solid waste per day. Corroborating the above ideas, ECYCLE [2] indicates that a small town with only ten thousand inhabitants could produce about ten tons of waste daily In this context, it is necessary to create solutions to mitigate the impacts arising from a linear flow of waste that causes new virgin materials to be inserted for the generation of products [3,4]. It is necessary to create solutions to mitigate the impacts arising from a linear flow of waste that causes new virgin materials to be inserted for the generation of products [3,4] This being the case, the opportunity arises to discuss the adoption of a circular economy perspective [5,6], this one being aimed at processes that link industrial ecology to waste management [7,8]. Silva et al [10] point out that production and consumption routines in a circular economy should be thought about from the perspective of an economic system analogous to biological ecosystems
