This study explores the importance of critical raw materials and minerals by analyzing the Republic of Korea’s recent circular economy and resource security policy. Raw materials and rare metals are becoming increasingly significant to the Korean economy because the country is currently shifting away from fossil fuels and nuclear power towards renewable energy resources as well as transforming its industries towards decarbonization, digitization, and automation. Korea is a resource-poor country and is heavily dependent on imported minerals and rare earths, which are essential for its economy and new industry. Responding to these challenges and concerns, Korea is moving towards a sustainable circular economy and achieving greater resource security. Despite certain limitations, this transition would ultimately contribute in preparing Korea for current and future challenges in the areas of critical raw materials and minerals.

Critical Raw Materials

Today human society is already witnessing rapid depletion of non-renewable ore resources. As the distribution of raw material resources globally is very off-balance, and preassure on environment as the consequence of ore exploatation is not negligible, re-utilization and recycling of industrial side-streams gaining on importance. Finding new potentially anthropogenic resources of material (at first place critical raw materials) are inline with sustainable waste management goals, and in correlation with boundaries given by the circular economy principles. Side-streams from mines can become source for recovery of these materials. The aim of this paper was to analyze position of mining waste in correlation with circular economy principles, as well potential for implementation of them within extraction industry in the Republic of Serbia.

Critical Raw Materials

Nowadays, the waste management sector faces a number of challenges. Changes in consumer habits generate huge amounts of industrial and household waste. Today’s trends, which involve a higher use of critical raw materials, such as in the manufacture of batteries and solar cells, make it urgent to extract valuable raw materials from waste. The waste sector as a whole, taking into consideration all levels of the waste hierarchy (prevention, reuse, recycling, energy recovery, landfilling), is a significant branch of the national economy, both in terms of employment and income-generating capacity. In addition, the sector can be considered a major intermediary in industrial value chains as it contributes to the generation of secondary raw materials that can be sold to industries and thus help to achieve a circular economy through the collection, treatment and processing of waste.

Subject. The article considers the concept of circular economy, which has originated relatively recently in the academic literature, and is now increasingly recognized in many countries at the national level. In the European Union, the transition to circular economy is viewed as an opportunity to improve competitiveness of the European Union, protect businesses from resource shortages and fluctuating prices for raw materials and supplies, and a way to increase employment and innovation. Objectives. The aim of the study is to analyze the incentives developed by the European Commission for moving to circular economy, and to assess their effectiveness on the basis of statistical analysis. Methods. I employ general scientific methods of research. Results. The analysis of the EU Action Plan for the Circular Economy enabled to conclude that the results of the recent research in circular economy barriers, eco-innovation, technology and infrastructure were successfully integrated into the framework of this document. Understanding the root causes holding back the circular economy development and the balanced combination of economic and administrative incentives strengthened the Action Plan, and it contributed to the circular economy development in the EU. Conclusions. The measures to stimulate the development of the circular economy proposed in the European Action Plan can be viewed as a prototype for designing similar strategies in other countries, including Russia. Meanwhile, a more detailed analysis of barriers to the circular economy at the level of individual countries and regions is needed.

Critical Raw Materials

Major benefits and constraints related to mineral extraction within the EU have been identified on the examples of selected critical raw materials’ deposits. Analyzed case studies include the following ore deposits: Myszków Mo-W-Cu (Poland), Juomasuo Au-Co (Finland), S. Pedro das Águias W-Sn (Portugal), Penouta Nb-Ta-Sn (Spain), Norra Kärr REEs (Sweden) and Trælen graphite (Norway). They represent different stages of development, from the early/grassroot exploration stage, through advanced exploration and active mining, up to reopening of abandoned mines, and refer to different problems and constraints related to the possibility of exploitation commencement. The multi-criteria analysis of the cases has included geological and economic factors as well as environmental, land use, social acceptance and infrastructure factors. These factors, in terms of cost and benefit analysis, have been considered at three levels: local, country and EU levels. The analyzed cases indicated the major obstacles that occur in different stages of deposit development and need to be overcome in order to enable a new deposit exploitation commencement. These are environmental (Juomasuo and Myszków), spatial (Juomasuo) as well as social constraints (Norra Kärr, Juomasuo). In the analyzed cases, the most important constraints related to future deposit extraction occur primarily at a local level, while some important benefits are identified mainly at the country and the EU levels. These major benefits are related to securing long-term supplies for the national industries and strategically important EU industry sectors.

Valley Of Death

Reducing the environmental pressure along the products life cycle, increasing efficiency in the consumption of resources and use of renewable raw materials, and shifting the economic system toward a circular and a climate-neutral model represent the heart of the current macro-trends of the European Union (EU) policy agendas. The circular economy and bioeconomy concepts introduced in the EU’s Circular Economy Action Plan and the Bioeconomy Strategy support innovation in rethinking economic systems focusing on market uptaking of greener solutions based on less-intensive resource consumption. In recent decades, industrial research has devoted enormous investments to demonstrate sustainable circular bio-based business models capable of overcoming the “Valley of Death” through alternative strategic orientations of “technological-push” and “market-pull”. The study highlights industrial research’s evolution on bio-based circular business model validation, trends, and topics with particular attention to the empowering capacity of start-ups and small and medium-sized enterprises (SMEs) to close the loops in renewable biological use and reduce dependence on fossil fuels. The research methodology involves a bibliographic search based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach and the European Innovation Council (EIC) Accelerator Data Hub investigation to understand SMEs’ key success factors and start-ups of the circular bioeconomy sector. Eco and bio-based materials, nutraceuticals, and microalgae represent the most sustainable industry applications, leading to circular bioeconomy business models’ future perspective.

AbstractThe increase in the world population leads to rising demand and consumption of plastic raw materials; only a small percentage of plastics is recovered and recycled, increasing the quantity of waste released into the environment and losing its economic value. The plastics represent a great opportunity in the circular perspective of their reuse and recycling. Research is moving, on the one hand, to implement sustainable systems for plastic waste management and on the other to find new non-fossil-based plastics such as polyhydroxyalkanoates (PHAs). In this review, we focus our attention on Tenebrio molitor (TM) as a valuable solution for plastic biodegradation and biological recovery of new biopolymers (e.g. PHA) from plastic-producing microorganisms, exploiting its highly diversified gut microbiota. TM’s use for plastic pollution management is controversial. However, TM microbiota is recognised as a source of plastic-degrading microorganisms. TM-based plastic degradation is improved by co-feeding with food loss and waste as a dietary energy source, thus valorising these low-value substrates in a circular economy perspective. TM as a bioreactor is a valid alternative to traditional PHA recovery systems with the advantage of obtaining, in addition to highly pure PHA, protein biomass and rearing waste from which to produce fertilisers, chitin/chitosan, biochar and biodiesel. Finally, we describe the critical aspects of these TM-based approaches, mainly related to TM mass production, eventual food safety problems, possible release of microplastics and lack of dedicated legislation.

Nowadays, circular economy (CE) is on the agenda, however, this concept of closed supply chains originated in the 1960s. The current growing quantity of studies in this area accounts for different discourses except the holistic one, which mixes both approaches—contextual and operating (contextual approach utilizes the thorough examination of the CE theory, stricture of the policy, etc.; the operating one uses any kind of statistical data)—to assess the capacity of circular economy regulatory policy packages (CERPP) in operating raw materials and industrial wastes. This article demonstrates new guidelines for assessing the degree level of capacity (DLC) of CERPPs in the operation of raw materials and industrial wastes by utilizing the apparatus of the fuzzy set theory. It scrupulously surveys current CERPPs in three regions: the EU overall, Finland and Russia; and assesses for eight regions—the EU overall, Finland, Russia, China, Greece, France, the Netherlands and South Korea—the DLC of CERPPs in operating raw materials and industrial wastes. The results show that EU is the best in CE policy and its CERPP is 3R. The following are South Korea and China with the same type of CERPP. Finland, France and the Netherlands have worse results than EU with the type of CERPP called “integrated waste management” because of the absence of a waste hierarchy (reduce, recover, recycle). Russia closes the list with the type of CERPP “basic waste management”.
