Ideal Framework

People in the world are more concerned about environment protection than ever before, which calls for green manufacturing (GM) and industrial ecology. With more eco-industrial parks (EIPs) built up recently in China, this GM, however, is progressively integrated into a ideal framework featuring in economies of scale as well as circular economy, aiming at saving energy, protecting the environment and sustaining economic growth. Jiangxi provincial government commits itself to constructing ten EIPs, one of which is Hengfeng EIP that succeeds both in business & investment invitation and circular economy. Likewise, some of the issues surrounding the environmental performance and resource management require a lot of exploration.

Operational Practices

In many developing countries, the informal recycling sector is responsible for reducing the amount of waste in landfills and supplying the needs of recycling industries. In the context of municipal solid waste (MSW) management, considering that developing countries aim to implement circular economy (CE) actions, it is essential to ensure the inclusion of waste pickers (catadores) in an adapted CE structure. This study analyzes the integration of recycling cooperatives in the formal management of municipal solid waste with recyclable potential (MSWRP) of a medium-sized municipality in Brazil, with the objective of ascertaining the contributions of cooperatives in an adapted CE structure and, at the same time, identifying a cooperative that can be used as a benchmarking option for other cooperatives, especially in relation to their organizational and operational practices. The results indicate that from this integration, cooperatives have legal responsibility in the management of MSWRP, resulting in the professionalization of its members and increasing their productivity. The results also revealed that the implementation of the CE in developing countries is, in a sense, conditioned to the performance of the informal sector in the recycling chain and, in addition, that the inclusion of cooperatives in the formal sector of MSWRP management can improve the rates of a municipality.

The article addresses the issue of green manufacturing in the context of global trends of consumption for various types of industrial products, respecting the concepts of circular economy. The article focuses on impact of global trends of consumption on green manufacturing dimensions (research and design process, waste control, packaging control, manufacturing control and quality control) of Romanian industry sustainable development. The authors have achieved a “correlation matrix of green manufacturing dimensions and global trends of consumption for production systems”.

Green Manufacturing and Recycling Economy is the basis for the sustainable development of human society, is also the direction for the future development of manufacturing industry. This article describes the concept of Green Manufacturing and Recycling Economy, analyses the work of Green Manufacturing processes, from product design, production, recycling-oriented three-pronged explained, and presents three suggestions of Green Manufacturing for circular economy, including extending the product life cycle, establishing enterprise's return goods processing center and strengthening cooperation with relevant manufacturers. Through these methods can enable enterprises to achieve the recycling of materials and energy, and enable enterprises to reduce production costs, improve core competitiveness.

Plural Rationalities

The concept of agency is increasingly used in the literature on sustainability transitions. In this paper, we add to that discussion by arguing that the concept of rationality opens new avenues to theorizing relational agency in transitions toward a circular economy. To this end, we compare rationality conceptions from management (e.g., collaboration and competition) with critical theory perspectives on rationality (e.g., instrumental and communicative rationality). This leads us to develop a typology matrix for describing plural rationalities underpinning relational agency. We illustrate this typology using excerpts from an in-depth case study of an ongoing city-coordinated ecosystem that develops a smart technology-enabled urban area based on the principles of circularity. The first contribution of this interdisciplinary paper is to offer a rational perspective on theorizing the antecedents of relational agency in circular economy transitions, where communicatively rational action enables agency and change. Secondly, our paper contributes to the literature on circular cities through conceptualizing circular transition as simultaneous collaboration and competition. Thirdly, our paper introduces a dyadic perspective on rationality to the literature on coopetition and provides an operating space from which professionals can navigate, depending on the type of coopetitive situation.

Managerial Implications

The implementation of scrap recovery activities has been shown to improve the financial performance of many firms, and this kind of circular economy (CE) is particularly evident in industries with green manufacturing (GM). In this paper, we consider an imperfect multiple-stage production system that manufactures paired products made from mixed materials containing scrap returns, in which the scrap returns are converted from defective products. The feed rates of scrap returns for two products are different, and the product with the higher feed rate is placed in the second order of the process to avoid unlimited accumulation of scrap returns. The proposed problem is formulated as a joint economic order quantity (EOQ) and economic production quantity (EPQ) model aimed at cost minimization. The decision variables of the proposed model include the production run time of two products, order quantity of new material, and the extent of investment in converted equipment. We also prove that the optimal solution exists uniquely and provide an algorithm for the computation of the optimal solution. Finally, a numerical example involving the pulp and paper manufacturing industry is provided to illustrate the solution process, and the results of its sensitivity analysis are also presented to show some managerial implications.

Woman worker has to get more attention in the formal sector of their role, beside of informal sector. Because of the women role has sufficient potentially toward the labor market. The number of commuter woman workers are getting increased in the formal sector. This is also influenced by the owner of the business to be trusted on the productivity of commuter woman workers. The urban sector of economic offers more formal sector especially service sector. Woman workers regarded more proper to be in the formal sector that concerning to woman character for the reason of helping family economically, the concept of gender encourages woman workers to tend to have the spirit for doing work better. The effect of modernization has become one of mobilizing to women in the rural area to an urban area even behavior or transportation. Conformity of woman characteristic informal sector encourages the productivity of workers in the service sector.
