Analysis of national policies for Circular Economy transitions: Modelling and simulating the Brazilian industrial agreement for electrical and electronic equipment

Analyzing the role of environmental policy innovations and natural resource management in driving circular economy forward: Evidence from BRICS economies

In understanding the dynamics of a circular economy, natural resources require careful management and mitigation strategies to prevent its detrimental effects on sustainable practices. Natural resource management and environmental policy innovations involve the balanced use and conservation of natural resources for sustainable and circular economic practices. This study analyses the impact of natural resource protection, natural resource depletion, and environmental policy innovations on circular economy using panel data from BRICS economies from 2000 to 2020. The study employed an Augmented Mean Group (AMG) and Common Correlated Effect Mean Group (CCEMG) econometric method along with cross-sectional dependence, 2nd generation unit root tests, heterogeneity, cointegration, and JKS Granger non-causality. Both econometric methods revealed that natural resource protection and environmental policy innovations accelerate circular economy practices. In contrast, natural resource depletion and non-renewable energy consumption decelerate the circular economy practices in the BRICS economies. Furthermore, the study found that natural resource depletion has a nonlinear impact, and higher depletion has the worst impact on the circular economy. Significant cointegration and causality have been observed. The study suggests natural resource conservation and transition to renewable resources to enhance the circular economy in BRICS economies.

A Recent Digitalization in Recycling Industry Attaining Ecological Sustainability: A Comprehensive Outlook and Future Trend

The management of waste through dual way of recycling (i-e offline and online) is assumed to have a key role in attaining ecological sustainability and enabling circular practices. The research on online recycling is gaining evolution in recent age. Prior literature on the current research theme has failed to provide a comprehensive outlook and future trend. Therefore, the current research intends to elaborate the current research scenario linked with online recycling by critically scrutinizing the prior research over the last 41 years. A comprehensive analysis was conducted using the Scopus database, retrieving a total of 866 articles. These articles were selected to provide a conceptual overview and understanding of the fundamental research conducted in the field. By employing bibliometric analysis this research provides comprehensive detail about evolution, mapping of publications and prominent trends from the year 1981 to 2022 to understand the practices and future trends of online recycling research. The outcomes elucidated that there is exponential increase in research publications relating to online recycling over the last five years. The most influential producer of online recycling research are China, United Kingdom and United States. Chinese Universities has the highest number of publications among all the countries across globe. Moreover, the current research trend is focused on technology based circular economy, industrial ecology, bio-based waste management, dual channel recycling, municipal waste, waste from electrical and electronic equipment (WEEE), environmental impact and lifecycle assessment. Hence, the prominent research perspective and highlighted features could offer recommendation for upcoming studies to contribute in literature and help practitioners, policymakers and professionals move towards circular practices.

The (un)shared responsibility in the reverse logistics of portable batteries: A Brazilian case

The Brazilian National Solid Waste Policy (BNSWP) determines that reverse logistics (RL) of waste batteries is mandatory and adopts the principle of shared responsibility among stakeholders. In this work, we sought to diagnose the current state of the RL chain for batteries in Vale do Aço, Brazil, and identify challenges and potentialities related to its improvement. Data were obtained by means of questionnaires sent to the main stakeholders involved in the batteries RL chain and by consultation of official Brazilian databases. The results showed that the main obstacles to the implementation of the RL of portable batteries in the region are: the lack of information by consumers and retailers regarding the BNSWP and management of waste batteries; the existence of few collection and consolidation points in the region; lack of municipal waste management plans; and lack of sustainability of waste picker organizations. The identified potentialities were: the good receptivity of environmental education actions by the population; the possibility of taking advantage of direct logistics of local retail chains to collect waste; the existence of a special waste management and transportation company in the region; and the existence of waste picker organizations interested in integrating the RL system. Finally, by a SWOT analysis, strategies for the implementation of a more effective RL system were drawn up. This work can serve as a basis for the structuring and implementation of the batteries RL system at the Metropolitan Region of Vale do Aço (MRVA) and can be a reference for other settings.

Implementation of Circular Economy Strategies within the Electronics Sector: Insights from Finnish Companies

There is an increasing call for products following circular economy principles. Despite growing pressure, understanding of the current situation and development vectors is largely missing. In this study, circular economy workshops were arranged for six industrial companies manufacturing electronics and operating in Finland to obtain an empirical understanding of the current state of circular economy implementation. During the workshops, each company assessed the state of the circular economy for a chosen product using a set of 51 circular economy strategies, i.e., the circularity deck. The results indicated that circular economy principles were implemented in only 25% of the cases. This is mostly related to the production of smaller, thinner, and lighter products. The results also indicate a large improvement potential of 36% for the participating companies. This is the share of cases that are planned for implementation. Those strategies mostly relate to the use of recycled inputs, the development of products made of a single material, and the design of products suitable for primary recycling. The least relevant or even irrelevant strategies were those related to the use of information technologies and artificial intelligence, despite electronic products being the enablers of such strategies for the other companies. Therefore, to further increase the circularity of electronic products and to meet the demands and interests of the manufacturing industry, research work on the technologies and services enabling the use of waste as raw materials should be emphasized to close the loops. Finally, the results imply the necessity for a more widespread assessment of circular economy strategies among companies, with consequent development of action plans for their implementation.
