“…As there is not any possibility of exchange, adherence to CE practices requires time and investment in training or consulting, which makes it an unfeasible change." Common concerns such as climate change, resource scarcity and other environmental issues require deep discussions and shared experiences (Korolev et al, 2018).…”

“…Gama Company believes that CE practices would be more easily implemented if organizations shared the knowledge they gained: “Even companies operating in different markets behave as competitors and keep their experiences confidential.

Purpose-In total, 19 practices of circular economy divided into three groups, internal environmental management, ecological design and investment recovery were studied in a local network composed of small companies and individual entrepreneurs related to common product and by-product flows. The paper aims to discuss these issues. Design/methodology/approach-This research presents an applied nature, is characterized as exploratory and adopted the case study as a technical procedure using sources and methods of data collection. The primary data were collected through direct observation of the processes and semi-structured interviews with managers and owners. Findings-The most widespread practices are related to product design. However, in most cases, the implementation was punctual and did not present continuous and corresponding actions, which highlights the embryonic contours of European Commission (EC) in the observed network. The practices from the management category were less observed, which revels the environmental variable is not included in the strategic business planning. Research limitations/implications-The research documents the application of CE practices in a local network and brings this current paradigm shift to the Brazilian context. Practical implications-To overcome barriers to the implementation of EC practices, it is suggested to restructure commercial relations, to formulate public policies and to develop infrastructures that facilitate the materiality of flows and the market. Social implications-The study highlights the need of public policies that promotes cross-sectoral cooperation in accordance with NSWP objectives. Originality/value-Despite the focus on EC implemented practices this study offers a framework of the research routes on the main barriers and suggests actions to overcome the challenges in the transition from the economy to the circular model.

“…Electrodeposition with redox replacement (EDRR) is a relatively new pulsed deposition technique for the recovery of precious metals such as silver, [21][22][23][24] gold [25][26][27] and platinum, 28 present at ppm levels in industrial process streams with a high concentration of non-noble metals such as copper. Its main feature is the use of short electrodeposition pulses followed by longer open circuit periods where the trace precious metal in solution spontaneously replaces the less noble metal that was electrodeposited, due to the difference in reduction potential between the two metals.…”

“…31 In some of these studies, the elemental composition and total deposited amounts were calculated by removing the working electrode from the cell, and stripping off the deposited layer ex situ to analyze it through ICP-MS or ICP-OES. 25,27,29,32 Alternatively, metal recovery calculations were performed by analyzing the solution with ICP-MS before and after EDRR. 26 Static EQCM cells have also been used in EDRR and surface limited redox replacement (SLRR) studies to describe the electric potential and mass transients involved in deposition and redox replacement processes.…”

We developed a new on-line hyphenated flow injection analysis technique (FI-EQCM-ICP-OES) that allows electrochemical deposition and stripping with mass detection and elemental analysis. This technique was used to study a new system for electrochemical recovery of silver from a 0.5 mM Ag+/5 mM Cu2+/0.5 M H2SO4 solution by pulsed electrodeposition with redox replacement (EDRR) in a small flow cell. The metal ions in a 500 μl sample are injected into the sulfuric acid carrier stream and deposited onto an electrochemical quartz crystal microbalance (EQCM) electrode housed in a 50 μl flow cell. The deposits are subsequently stripped off electrochemically in the same cell and analyzed downstream in an ICP-OES. The stripped metal layer was found to be composed of Ag with no detectable Cu for a redox replacement time of 10 s, and 91 wt.% Ag–9 wt.% Cu for a redox replacement time of 5 s. Microscopy measurements demonstrated that the electrode was covered with silver particles, some of which contain Cu in the case of the 5 s replacement time. This technique allowed the study of mass changes on the electrode during electrodeposition and open circuit times in each EDRR cycle in flowing solutions.

“…Despite the fact that the metal concentrations in these materials are relatively low, the involved volumes are so large that they could secure an independent source of critical metals for Europe. The European Training Network SOCRATES [2] targeted technological innovation for the sustainable, nearly zero-waste valorisation of such metal-bearing industrial process residues. By unlocking the potential of secondary raw materials, the SOCRATES project aimed to contribute to a more diversified and sustainable supply chain for metals in Europe.…”

The accomplishment of the goals set in the EU Green Deal and the Agenda 2030 for Sustainable Development requires a metallurgical industry that is even more resource-efficient, environmentally friendly and socially responsible than it is today. The European Training Network SOCRATES has taken this up by developing groundbreaking metallurgical processes for the valorisation of industrial intermediate products. This short article summarizes the results obtained in the four-year project and discusses the outcomes in light of the recently adopted EU Green Deal.
