Special Issue Information

Dear Colleagues,

This Special Issue focuses on empirical and theoretical studies of systems transitions from linear to circular modes of production, and consumption.  

Governments, industry and society are increasingly recognizing the imperative to transition to a circular economy. Though sometimes viewed as a panacea to the economy versus environment dichotomy, the circular economy paradigm goes against the grain of more than two centuries of economic development and theory. Here, production efficiency is optimized through mono-tasking within siloed areas of resource extraction, process, manufacture, distribution, consumption, disposal, and waste management, where externalities outside each process of the value chain are mostly unaccounted for. On the other hand, the objectives of a circular economy to close, slow, and narrow material flows whilst sustaining natural systems necessitates system-wide approaches and collaboration among various actors along the entire value chain in a way that optimizes social, economic, and environmental performance. This Special Issue seeks to explore the current state of play in the transition of complex systems— both existing, planned, and future—to draw lessons that can be applied to other sectors and jurisdictions.

The Special Issue seeks to include research articles that apply wholistic systems analysis methods from economic, engineering, and/or the social and policy sciences. Cross-disciplinary studies are encouraged. Systems of interest range from the microscale (e.g., organizations, communities), mesoscale (e.g., supply chains, eco-industrial parks, cities) through to the macroscale (sub-national, national, or regional). Systems transitions may be sector-specific (e.g., ag-food systems, manufacture) or focused on materials or products (e.g., rare earth minerals, plastics, textiles, batteries). Approaches might include the application of traditional economic theories (e.g., rational choice theory or behavioral economics) to predict the uptake of CE approaches, products, and services; quantitative systems analyses such as techno-economic and/or life cycle assessments, material flows analyses, and/or environmental accounting; market analyses; sustainability assessments; soft systems methodologies to identify leverage points; triple bottom line models or empirical evaluations of economic, environmental, and social performance; or comparative case analyses of linear and CE systems.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

This study proposes a nitrogen recycling system that collects and recycles nitrogen compounds from waste gases in the industrial sector, such as those from stationary sources, from industrially processed wastewater containing livestock effluent, and from household wastewater. Multiple scenarios are set, and the potential global flows of anthropogenic nitrogen in 2050 are estimated and compared to assess the effects on the largest planetary boundary problem. In contrast to the business-as-usual (BAU) scenario, in which environmental conditions are worsened through a 47% increase in nitrogen emissions by 2050 above the 2010 levels, the agricultural countermeasures scenario produced a reduction in emissions which was less than the 2010 levels. The industrial countermeasures scenario proposed in this study achieved comfortable reductions in nitrogen production by constructing a nitrogen recycling system that installs the nitrogen compounds to ammonia (NTA) technologies. Combining the agricultural and industrial countermeasures achieves a 66% reduction in nitrogen emissions compared with the BAU scenario in 2050. The combination of both countermeasures with a high installation rate of NTA technologies can achieve the reduction of nitrogen emissions beneath the planetary boundary. Full article
