The idea of the circular economy is conceptualized as the basic transformative, integrative philosophy, which is the basis of ecological and economic policy of public-private partnership. It is found that the intensification of competition for resources leads to increased waste production and pollution, which led to the formation of an economic system. Its components are renewable energy sources, increased production of waste from production waste, minimization of food waste and improving the quality of life of all segments of society. All successful micro-industries have been found to be the product of successful business start-ups. The author identified the key factors of the circular economy: the potential of the Fourth Industrial Revolution; circular value chains based on recycled waste; leaders in the circular economy; cooperation. The analysis of the circular business model made it possible to prove that it can include one or a set of the following elements: circular design, optimal use, value recovery, network (chain) organization. Those ones represent the circular economy as a global imperative of the formation and development of its architecture.

Biomass For Energy

Biomass is seen as one of the most dominant future renewable energy sources. In detail, agro-industrial by-products represent a cheap, renewable, and abundant feedstock useful for several new products, including biochemical, biomaterials, and above all biogas, which are taking on an ever-increasing role in Italy. In this context, the tomato chain was analysed aiming at estimating the amount of processed tomato and the related waste production as a new suitable resource for producing biofuel as a new frontier within the context of a circular economy. Due the importance of the tomato industry, this research aims at filling gaps in the knowledge of the production and yield of the by-products that are useful as biomass for energy use in those territorial areas where the biomethane sector is still developing. This aim could be relevant for planning the sustainable development of the biomethane sector by reducing both soil consumption for dedicated energy crops and GHG emissions coming from the biomass logistic supply. The achieved results show the localization of territorial areas highly characterized by this kind of biomass. Therefore, it would be desirable that the future policies of development in the biomethane sector consider the availability and the distribution of these suitable biomasses within the territory.

The article discusses the basic principles of the implementation of the transition from a linear economy to a circular economy model. The article summarizes the existing problems that require solutions to create new jobs, increase economic growth, and create a balance between the economy, environment and population. The authors present examples of building a circular economy model in foreign countries. The importance of the tasks of implementing and promoting the circular economy was revealed, thanks to the involvement of all participants in the society in this process and the motivation for companies and investors. Effective tools for moving society towards a resource-efficient closed-cycle economy, increasing energy efficiency, energy conservation and reducing the energy intensity of the gross domestic product, due to the entry into a competitive level of renewable energy sources are investigated. The introduction of digital technologies and artificial intelligence in automated accounting of resource consumption, as well as the improvement of accounting rules will create opportunities for the end user to manage resource consumption taking into account the principles of a circular economy. The authors' study emphasizes that circular economy products and services should minimize resource use and promote reuse, recovery and recycling of materials in the future, leveraging existing product policy instruments, further support for the repair sector, improved design for reuse, and high-quality packaging recycling. The authors in the article propose to legislate the subsidizing of enterprises participating in the circular chain and subsidizing innovative developments in the field of the circular economy in the Russian Federation.

Growing consumerism and population worldwide raises concerns about society’s sustainability aspirations. This has led to calls for concerted efforts to shift from the linear economy to a circular economy (CE), which are gaining momentum globally. CE approaches lead to a zero-waste scenario of economic growth and sustainable development. These approaches are based on semi-scientific and empirical concepts with technologies enabling 3Rs (reduce, reuse, recycle) and 6Rs (reuse, recycle, redesign, remanufacture, reduce, recover). Studies estimate that the transition to a CE would save the world in excess of a trillion dollars annually while creating new jobs, business opportunities and economic growth. The emerging industrial revolution will enhance the symbiotic pursuit of new technologies and CE to transform extant production systems and business models for sustainability. This article examines the trends, availability and readiness of fourth industrial revolution (4IR or industry 4.0) technologies (for example, Internet of Things [IoT], artificial intelligence [AI] and nanotechnology) to support and promote CE transitions within the higher education institutional context. Furthermore, it elucidates the role of universities as living laboratories for experimenting the utility of industry 4.0 technologies in driving the shift towards CE futures. The article concludes that universities should play a pivotal role in engendering CE transitions.

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.

The role of a forest sector in the transition to a circular economy (CE) is critical. Therefore, the purpose of this study is to summarize the main findings of the most important published articles and to provide insights on the interdisciplinary space at the interface of concepts related to a forest-based CE. Moreover, it attempts to assess the challenges raised from adopting the CE in forest sector. Through a systematic literature review, 69 scientific publications were selected and evaluated by two sights: (i) a descriptive analysis and (ii) a cluster analysis of the keywords related to the forest-based CE. The study highlights the need for additional survey on optimizing the interaction between forest ecosystem services and circular economy. Further discussion is also needed about the relations of the key factors associated with the forest-based circular economy, as they emerged from the cluster analysis and the co-occurrence network map.

The circular city is emerging as new concept and form of practice in sustainable urban development. This is a response to the complex and pressing challenges of urbanization, as highlighted in the New Urban Agenda (NUA). The concept of a “circular city” or “circular city-region” derives from the circular economy model applied in the spatial territorial dimension. It can be associated with the concept of a “self-sustainable” regenerative city, as stated in paragraph n.71 of the NUA. This paper aims to develop an extensive form of “screening” of circular economy actions in emerging circular cities, focusing on eight European historic port cities self-defined as “circular”. The analysis is carried out as a review of circular economy actions in the selected cities, and specifically aims to identify the key areas of implementation in which the investments in the circular economy are more oriented, as well as to analyze the spatial implications of the reuse of buildings and sites, proposing a set of criteria and indicators for ex-ante and ex-post evaluations and monitoring of circular cities. Results show that the built environment (including cultural heritage), energy and mobility, waste management, water management, industrial production (including plastics, textiles, and industry 4.0 and circular design), agri-food, and citizens and communities can be adopted as strategic areas of implementation of the circular city model in historic cities, highlighting a lack of indicators in some sectors and identifying a possible framework for “closed” urban metabolism evaluation from a life-cycle perspective, focusing on evaluation criteria and indicators in the (historic) built environment.

Food, the basic connecting unit of all the UN's Sustainable Development Goals, plays a crucial role in the ecological transition towards a circular economic paradigm. This paper takes scientific considerations as a starting point in order to contribute to the definition of a theoretical-operational framework in which to grow the Circular Economy for Food. This is a still-open question in a sector of the circular economy that is emerging as vital to sustainable development. The 3 C's of Capital, Cyclicality and Co-evolution offer a systemic, holistic vision of the food system's role. Within this conceptual framework, the designers can find the main boundaries of the system, within which to express their creativity. The aim must be to avoid damaging relationships with the best supplier of raw material known to humanity (Nature), respecting planetary boundaries and at the same time offering a fair space to civil society.

The 21st century is known as the industrial revolution 4.0 which changes the economy among people who grow together with modernity and technology systems. It proves that the development of human thinking on creativity will greatly affect the development of the creative economy, but this has made the market begin to be abandoned by new generations and switch to e-commerce systems. The existence of an epidemic that has begun to spread in people's lives is also one of the factors that have changed the world economy and made the market begin to be abandoned. Changes in the world economy will require revitalization so that this is used as a foundation in the formation of the Screen Market integrated with the digital system to polarize the economy. The new generation is the key to the development and balance of the economy in technology, this is in line with the entrepreneurial nature and character of the new generation, which makes them prefer to develop as start ups. The revitalization of the economic center will become a forum for interaction with the surrounding environment so that the characteristics of the formation of interaction space are the basis and the beginning of the screen market. The screen market is located on Jl Arjuna Utara which is surrounded by malls, offices, universities, making the type of retail being marketed a creative sub-sector, namely culinary with local products, fashion retail, and also craft retail managed by start ups so it is hoped that the screen market can accommodate interaction and creatively combined with digital developments. Keywords: Economy; Market; New Generation; Technology. Abstrak Abad ke-21 dikenal dengan terjadinya revolusi industri 4.0 yang mengubah  perekonomian  di kalangan masyarakat yang bertumbuh bersama dengan sistem modernitas dan juga teknologi. Membuktikan bahwa perkembangan pemikiran manusia terhadap kreativitas akan sangat memengaruhi perkembangan ekonomi kreatif tetapi hal ini menjadikan pasar mulai ditinggalkan oleh generasi baru dan beralih pada sistem e-commerce. Adanya wabah yang mulai merambat dikehidupan masyarakat juga menjadi salah satu faktor yang merubah perekonomian dunia dan menjadikan pasar mulai ditinggalkan. Perubahan perekonomian dunia ini akan membutuhkan revitalisasi sehingga hal ini dijadikan sebagai landasan pijakan dalam pembentukan Pasar Layar yang dipadukan dengan sistem dari digital sebagai polarisasi perekonomian. Generasi baru merupakan kunci dari perkembangan dan keseimbangan perekonomian dalam teknologi, hal ini sejalan dengan sifat dan watak entrepreneur yang dimiliki oleh generasi baru sehingga menjadikan mereka lebih memilih berkembang sebagai start up. Revitalisasi pusat perekonomian ini akan menjadi wadah interaksi dengan lingkungan sekitar sehingga adanya karakteristik pembentukan ruang interaksi sebagai dasar dan awal dalam pasar layar.

<p>New Zealand is ranked among the top nations in waste production, including a million tonnes of plastic waste. Currently, there are methods for recycling plastic within New Zealand but these methods can be expensive and time-consuming, resulting in most of the plastic being thrown into the landfill. Because plastic does not fully degrade, it ends up in the ocean and other waterways, poisoning the water with toxins. The purpose of this research is to provide a solution to reducing plastic waste by creating an alternative method of recycling that utilises new technologies such as additive manufacturing, to create a building material that fits into the concept of the circular economy. The findings of this research explored the recycling of plastic by collecting plastic waste such as PLA (Polylactic Acid) from old 3D printed models. The plastic was recycled into filament for additive manufacturing (AM) and used to print building tile, establishing an initial proof of concept for the use of recycled plastic as a potential building material.</p>
