Are you interested in circular economy?
Summary of the article titled Circular economy: a brief literature review from 2021 by Erick Hungaro Arruda, Rosangela Andrade Pita Brancalhao Melatto, Wilson Levy, and Diego de Melo Conti, published in the Sustainable Operations and Computers journal.
This is a great preparation for our next interviewee, Dr Nicole Garofano in episode 171 talking about circular economy.
Since we are investigating the future of cities, I thought it would be interesting to see circular economy as an effective tool to trigger sustainable developments. This article presents many understandings and the evolution of the circular economy in research, highlighting some future prospects for the concept.
As the most important things, I would like to highlight 3 aspects:

Circular economy proposes a change in the extraction-production-disposal paradigm of the current linear economy.
Circular economy is based on design of manufactured products with added value and maximum use in longer life cycles, creation of versatile products with multiple uses, restitution of solid waste to the industrial sector, and a systemic approach to supply chain management.
Circular economy is presented as a concept of sustainability with the greatest probability of favourable economic development.

Abstract: Hitherto implemented economic mechanisms and development processes have led the planet to face numerous environmental and ecological depletion challenges. In light of this, Circular Economy emerges as an effective tool for triggering a sustainable development process. This article aims to present different perspectives and concepts of circular economy. To that end, a qualitative study was conducted and the methodology of systematic literature review was applied, so as to obtain solid knowledge about the theme, using the most recent and relevant articles. Scielo, Science Direct and Google Scholar database were the source of the articles that met the defined criteria, described in six steps: search key words; only scientific articles considered; publication between 2015 and 2020; in English; with 100 or more citations; relevant content to the theme. As a result, an extract of the researched articles and a comparison between the scientific literature on this subject is presented, showing some evolution of the aspects of the Circular Economy, such as designing of new products, emerging of new legislation and adoption by industry. Although the study was not conclusive on how the evolution of Circular Economy will take place, authors suggest future studies to assess the transition towards an economic circularity. Also, it is recommended that future studies consider case studies as a model for assessing Ciruclar Economy progress in the light of legislation and economic interests.
