<p>In Canton Ticino, Switzerland, the exploitation of natural stone, mostly gneisses, is an important activity of valley’s economies but in the last decades the local quarries are facing severe economic difficulties. The current rules on the disposal of quarry wastes and the territorial planning that regulates the structure of quarries and inert landfills, is putting pressure on the economy and profitability of quarries, as the wastes represent up to 40% of the extracted material and disposal costs are huge given the important volumes. Therefore, the sustainable development of the quarry sector needs new and effective strategies, in particular in the management of quarry waste to reduce its disposal costs and possibly to re-enhance this material. Here, we propose an example of an environmentally friendly circular economy based on crushed aggregates of quarry waste for the building of high added value constructional elements.</p><p>In this applied study, we characterized the waste materials (different types of gneisses) and evaluated the crushed aggregates for their use in traditional concretes and in innovative geopolymers to use in 3D printing systems. The results showed that the concretes produced with 100% quarry waste (crushed aggregate) have good mechanical properties but moderate durability. However, it has been observed that even by simply mixing these crushed aggregates with a part of fluvial sand (allochthonous) it is possible to improve the performance of the concrete in all respects. Hence, this environmentally friendly material is suitable for many applications in the concrete industry. The aggregates were also tested for powder bed 3D printing that uses geopolymers as a binder. The first tests with this printed geopolymer suggest that this innovative constructional material may be used in non-structural architectural elements, however, further investigation is needed.</p><p>In this project it has been mapped, within the construction industry, how the economic supply chain could be configured for the reuse of this material. In particular, the usability in the production of concretes, geopolymers and mortars was highlighted, both in traditional applications and with innovative applications such as 3D printing. The analysis was carried out with particular attention to the concepts of circular economy and sustainability, identifying the main actors and their potential interests within the supply chain.</p>

The Farm-to-Fork strategy, launched in May 2020, is the first attempt at a European-wide approach to food systems of this scale. The strategy sets ambitious targets and aims to create a ‘fair, healthy, and environmentally friendly food system’. Yet, within the bounds of its own regulatory and legislative context (including the Green Deal, the Circular Economy Action Plan and the new Biodiversity Strategy 2030), the strategy falls short of recognising key links in and between the food system. This review posits that the strategy and its targets do not adequately consider the importance of transforming agricultural practices for environmental outcomes; of agricultural practices for nutrition outcomes; nor the links between how we value nutrition along the supply chain, from farm to fork

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 transition of the European agri-food sector towards a sustainable production and consumption model is a key element of the Green Deal. The new European “Farm to Fork” strategy aims to make the food system fair, healthy, and environmentally friendly. The consolidation and development of the organic model are two of the main objectives. In Italy, this development can be achieved through the Bio-District model. This model, which was born in the last ten years in Italy, is characterized by innovative multi-actor governance. From an explorative perspective, this study analyses the background literature on Bio-Districts and the context of the development of the Etruscan Roman Bio-District to understand the potential and the factors that allow the application of the principles of the Circular Economy. It focuses on multiple comparative analyses by using a qualitative–quantitative approach. The analysis of the context highlights the potential for expansion linked to an integrated short supply chain through three scenarios.

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.
