“…Well-known CE practices include 3Rs (Reduce, Reuse, Recycle), pollution prevention, product stewardship, eco-design, Life Cycle Assessment (LCA), Internal Environmental Management (IEM), green purchasing, cooperation with customers, refurbishing, and remanufacturing (Kalmykova et al 2018 ; Masi et al 2018 ). The positive impacts of CE projects on metals (Bendikiene et al 2019 ; Tan et al 2021 ), automotive (Yadav et al 2020 ), and fashion (Brydges 2021 ) industries, have been documented by previous empirical studies. So far, the sustainability effects of CE implementation at the supply chain level are still at the early stage of development compared to the firm level (Masi et al 2018 ).…”

The COVID-19 pandemic has widely disrupted manufacturing industries. This research focuses on how project management, Industry 4.0 technologies, and the Circular Economy contribute to Sustainable Supply Chain development during the pandemic. A multiple case study focusing on three companies in the metals industry, covering small-, medium-, and large-size companies from Thailand, is adopted to investigate the impact of the pandemic on companies using the dimensions of demand, production, and distribution disruptions. The result shows that project management supports Industry 4.0 technologies and Circular Economy adoption. Moreover, the COVID-19 pandemic also expedites Industry 4.0 technologies adoption. Product customization is one of the key focuses of the companies to differentiate from the competitors and create long-term competitive advantages. Industry 4.0 technologies and the Circular Economy have a positive influence on Sustainable Supply Chain development.

The term downcycling is often used anecdotally to describe imperfections in recycling. However, it is rarely defined. Here, we identify six meanings of the term downcycling as used in scientific articles and reports. These encompass the material quality of reprocessed materials, target applications, product value, alloying element losses, material systems, and additional primary production. In a proposal for harmonized and more specific terminology, we define downcycling as the phenomenon of quality reduction of materials reprocessed from waste relative to their original quality. We further identify that the reduced quality can express itself thermodynamically, functionally, and economically, covering all perspectives on downcycling. Dilution, contamination, reduced demand for recycled materials, and design-related issues can cause those downcycling effects. We anticipate that this more precise terminology can help quantify downcycling, keep materials in the loop longer, use materials more often and at higher quality, and therefore assist in reducing material-related environmental impacts.

“…Additionally, it is necessary to think about how a product will behave in the system by designing its disassembly or retrofit and estimating residues generated in its life cycle (Charef and Emmitt, 2021). Thenceforth, it becomes possible to use them as raw materials in the production of other products, or even return to nature as nutrients without any contamination risks (Blomsma, 2018; Dandamudi et al, 2021; García-Barragán et al, 2019; Tan et al, 2021).…”

Circular economy in Brazilian construction industry: Current scenario, challenges and opportunities

et al. 2021

View full text Add to dashboard Cite

The effective implantation of the circular economy (CE) presents a great challenge to the industrial sectors, mostly in those of greater environmental impact, such as construction industry. In Brazil, this industry has been growing over the last 20 years; however, such growth was based on an extractivist economy without any consideration to the end of its products lifespan. Only in 2017, 45 million tonnes of construction and demolition waste were generated in the country. This paper presents the current context of public policies in the Brazilian construction industry and proposes initiatives to introduce principles of CE. An exploratory study was developed, and all the 45 references presented in Appendix A of the review paper of Benachio et al. were considered to draw new ideas. These ideas are related and compared to key points in Brazilian regulations. Twelve opportunities for the improvement are listed and organized by construction stages (planning and design, materials manufacturing, construction processes, use and demolition). The ones related to design and planning using Green building information modelling, and materials manufacturing with recycled waste are highlighted due to the existing actions, standards, and Federal legislation. It was found that some sectors and the government already have actions related to CE (based on the 3R principle), but still there are several initiatives needed for its effective implementation in the Brazilian construction industry.
