AbstractImproved value generation and efficient use of resources are important steps national economies can implement to minimize the use of resources and mitigate the creation of waste and toxic emissions. The increase of resource efficiency is eminent to tackle the imminent challenges of depleting resources and the emerging environmental crisis. In this study, we explore the value generation and efficiency of resource recovery in waste streams in the most important economic sectors in Iceland, namely, (i) fisheries, (ii) domestic waste processing, (iii) geothermal energy production, and (iv) aluminium production. By describing the processes, the opportunities, and the market potential of the value generation through enhanced resource efficiency in the four case studies, we identify possible solutions towards a more sustainable society. The results reveal that the increase in resource efficiency reduces the environmental impacts, increases the economic output, and enhances the resilience of the economy. We conclude that the presented concepts of added value generation could be the first step towards a circular economy, adhering to a more sustainable world while preserving vital resources for the next generations. While our results are based on the presented examples in Iceland, the described processes of resource recovery can be applied in any other country with similar resources.

<p>Circular economy solutions reuse and upcycle waste streams in order to minimize the use of resources and mitigate the creation of waste and emissions. Accordingly, circular economy solutions are an essential tool to tackle the imminent challenges of depleting resources and the emerging environmental crisis. In this presentation, we explore the circular solutions for resource recovery in waste streams in a country with one of the highest Gross Domestic Product (GDP) and Human Development Index (HDI) in Europe, Iceland. The economy of Iceland is mainly based on renewable energy, fishery, farming, metallurgy, and tourism. To assess the benefits of circular economy solutions we examine four relevant case studies from the following industrial sectors in Iceland: i) a geothermal energy plant, ii) fisheries, iii) domestic waste processing and iv) aluminium production. By describing the processes, the opportunities and the market potential of the circular economy solutions in the four case studies we identify the superiority of circular recovery of resources in a modern society. The results reveal that the recovery of resources reduces the environmental impacts, increases the economic output and enhances the resilience of the local economy. While our results are based on the examples in Iceland the described processes of resource recovery can be applied in any other country with similar resources. We conclude that the presented circular solutions could lead to a more sustainable world while preserving vital resources for the next generations.</p>

This paper examines the hydrological cycle and its implications for the production capacity of two countries, China and the United States. While it takes a macro-level view, it illustrates the relevance of understanding the circularity of nature as exemplified by the hydrological cycle, for urban and regional circular economy considerations. Taking the circularity of nature as a starting point is a departure from common circular economy conceptions, which take an anthropocentric perspective rather than a nature based one. We calculate the amount of solar energy available for freshwater evaporation and the allocation of freshwater to its key uses in the domestic, industrial, and agricultural sectors. Our calculations indicate that the capacity to generate economic output can be accurately described by the embodied solar energy distribution that determines the availability of freshwater for allocation to different uses. This illustrates the need to take environmental/physical conditions more fully into account in economic development decisions at every level, from local to regional, national, and global. We begin our analysis with a review of circular economy concepts and argue that they reveal a limited understanding of the circularity of nature evident in energy and material cycles and their economic capacity implications. Achieving further expansions of economic capacity may increasingly depend on an improved understanding of nature’s circularity, especially when competing resource pressures and land-use constraint exacerbate economic capacity limits. Our findings suggest three particularly important lessons for decision makers: first, the efficiency increases needed to realize growing economic output will require circular economy models that consider the efficient processing capacity of nature rather than relying solely on technological solutions; second, the non-use of resources may be as valuable or more than their use; and third, price policies can be effective in steering resource use and non-use in the right direction.

The objective of this paper is to outline the potential and outlooks of development of circular economy in Bulgaria, as well as demonstrate the need for adequate measures on part of public authorities to encourage this change. The research is based on a primary survey of Bulgarian employers’ attitudes towards pursuing a corporate policy relating to the principles of sustainable development, which was conducted among 400 enterprises. The analysis reveals untapped potential not only with regard to a more efficient use of resources, in both the private and public sectors, but also in terms of underestimating the significance of the issue. The firms could significantly reduce their costs, improve their compatibility and their export potential if they apply new business models and new innovative technologies, which are both resource-efficient and eco-friendly. The research and analytical methods used for the development of the paper involve graphical and table presentation of statistical and empirical data and survey of available legal and analytical research on the topic. The conclusions reached reveal a number of obstacles slowing down the transition to a real circular economy model.  That would require speeding up the reform in the eco-fiscal and innovative government policies.  The paper’s added value lies not only in the analytical examination of the issues, but above all in deriving recommendations for future actions.

The article examines the development of the circular economy in Ukraine, as well as the prospects of implementation of the experience of leading EU countries in the field of circular economy in Ukraine. The relevance of the study is that for now in Ukraine very few steps have been taken towards a circular economy, although everyone understands its importance. First of all, the meaning of the circular economy is revealed and the main advantages of its implementation in Ukraine are determined. The advantages of the transition to a circular economy are as follows: significant material savings, sustainable use of resources, stimulating innovations, the ability to meet the needs of the ever-growing population of the Earth, economic growth, and income. The circular or closed-loop economy involves the recovery, reuse, and rational use of resources and, through services and smart solutions, leads to added value. The state of resource management in Ukraine and the EU, in particular waste management, is analyzed. It is established that in the field of waste management Ukraine lags far behind developed European countries. Today, huge amounts of waste have accumulated in Ukraine, and currently, there is no developed infrastructure to decide this problem, and landfills themselves have become sources of great environmental danger. The new EU policy and the policy of Ukraine in the field of circular economy are analyzed. Taking into account the best European practices, recommendations are given to Ukraine on the transition from a traditional, linear economy to a circular economy. The main ones are as follows: it is necessary to change the structure of public procurement and focus on environmentally friendly types of production; it is necessary to accelerate the transition of Ukraine from the traditional model of public procurement to the concept of “green” procurement; it is necessary to develop an effective legislative and regulatory framework for the functioning of the circular economy; it is necessary to move to more efficient business models (such as ecodesign, repair, reuse, recovery and exchange of products and maximum prevention of waste generation) and stimulate the development of environmentally friendly technologies; it is expedient to develop programs of financing of projects in the field of circular economy; it is necessary to promote better awareness of consumers about the concept of “circular” economy, environmental “footprint” of goods and services, as well as sustainable consumption; it is necessary to change the method of production and consumption of goods from short-term to long-term, as well as to encourage the economy, businesses and consumers to maximize waste recycling. It is also established that in general, Ukraine’s policy in the field of circular economy should be formed and implemented at all three levels: national, regional, and global. However, each of us can begin to change in the direction of a circular economy (for example, through conscious consumption and resource conservation). It is also important to realize the importance of sorting garbage because its removal to landfills and finding new ones is not the best solution. Garbage needs to be recycled, and this can only be done if it is sorted.

The current stage of development of the agricultural industry is characterized by high rates of automation of production processes. In this regard, the problem of rationalizing the process of distributing agricultural resources and organizing the production chain with added value is becoming more acute. An effective solution to this problem can be a closed-cycle economy model. This model can contribute to the rational use of resources, reduce production losses, and, as a result, improve the quality of products and their volumes. It is necessary to develop a general plan for the implementation of the main postulates of the closed-cycle economy in agriculture, gradually implement the circular economy strategy and include new industrial circular economy in the process of modernization of a particular branch of agriculture. In some areas of agriculture, a cycle of production systems should be established as soon as possible. With the basic implementation of new industrial technologies and industrial development, as well as the stability of the reserves of social resources, it is necessary to steadily increase the new cycle of industrialization in agriculture.

Currently, agricultural production generates large amounts of organic waste, both from the maintenance of farms and crops, and from the industrialization of the product. Generally, these wastes are accumulated in landfills or burned, sometimes causing environmental problems. However, many scientific studies suggest that these residues are rich in bioactive compounds, so these matrices could be revalued for their use in food, cosmetic, or pharmaceutical industries. In this way, the circular and sustainable economy is favored, while obtaining products with high added value. In this case, this approach is applied to the residues generated from kiwi production, since numerous studies have shown the high content of kiwi in bioactive compounds of interest, such as phenolic compounds, vitamins, and carotenoids. These compounds have been reported for their antioxidant, anti-inflammatory, and antimicrobial activities, among other beneficial properties for health such as its use as prebiotic. Therefore, this article reviews the potential of residues derived from industrial processing and agricultural maintenance of kiwi as promising matrices for the development of new nutraceutical, cosmetic, or pharmacological products, obtaining, at the same time, economic returns and a reduction of the environmental impact of this industry, attaching it to the perspective of the circular economy.

Following the growth of the global population and the subsequent rapid increase in urbanization and industrialization, the fisheries and aquaculture production has seen a massive increase driven mainly by the development of fishing technologies. Accordingly, a remarkable increase in the amount of fish waste has been produced around the world; it has been estimated that about two-thirds of the total amount of fish is discarded as waste, creating huge economic and environmental concerns. For this reason, the disposal and recycling of these wastes has become a key issue to be resolved. With the growing attention of the circular economy, the exploitation of underused or discarded marine material can represent a sustainable strategy for the realization of a circular bioeconomy, with the production of materials with high added value. In this study, we underline the enormous role that fish waste can have in the socio-economic sector. This review presents the different compounds with high commercial value obtained by fish byproducts, including collagen, enzymes, and bioactive peptides, and lists their possible applications in different fields.

There is a growing debate surrounding the contradiction between an unremitting increase in the use of resources and the search for environmental sustainability. Therefore, the concept of sustainable degrowth is emerging aiming to introduce in our societies new social values and new policies, capable of satisfying human requirements whilst reducing environmental impacts and consumption of resources. In this framework, circular economy strategies for food production and food loss and waste management systems, following the Sustainable Development Goals agenda, are being developed based on a search for circularity, but without setting limits to the continual increase in environmental impacts and resource use. This work presents a methodology for determining the percentage of degrowth needed in any food supply chain, by analyzing four scenarios in a life cycle assessment approach over time between 2020 and 2040. Results for the Spanish case study suggested a degrowth need of 26.8% in 2015 and 58.9% in 2040 in order to achieve compliance with the Paris Agreement targets, highlighting the reduction of meat and fish and seafood consumption as the most useful path.

Circular Economy is the solution for the current environmental crisis, representing a huge economic opportunity to build new sustainable businesses. However, many barriers need to be faced for its implementation at industrial scale—firstly, the lack of data sharing between the different stakeholders of product value-chains. The DigiPrime project is an EU-funded Innovation Action aimed at developing and demonstrating a digital platform with services able to unlock innovative cross-sectorial business models for the remanufacturing and recycling of target value-added products. In this paper, the concept behind the DigiPrime project is reported, with a particular focus on the construction sector.
