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.

AbstractNowadays, the world is shifting towards a more sustainable way of life, and product designers have an important part in this change. They have to eco(re)design their products to make them environmentally conscious throughout their lifecycle, and especially at their end-of-life (EoL). However, one can observe that synergy between product designers and recycling-chains stakeholders is lacking, mainly due to their weak communication. While many design-for-EoL approaches coexist in the literature, design from EoL must also be taken into account to fully develop a circular economy.RE-CYCLING is an innovative design approach that supports both design for and from EoL. This paper focuses on the recycling EoL-option and the validation of the associated indicators. To validate the design-for-recycling indicators, the recyclability of three smartphones is assessed. It is expected that indicators provide a similar score as none of them was designed to be recycled; results comply with expectations. In parallel, the convenience of using recycled materials in smartphones is analysed to validate our design-from-recycling indicators. It is found that the proposed indicators can indeed support designers integrating recycled materials in products.

The building industry is blamed for consuming enormous natural resources and creating massive solid waste worldwide. In response to this, the concept of circular economy (CE) has gained much attention in the sector in recent years. Many pilot building projects that implemented CE concepts started to appear around the world, including Taiwan. However, compared with the pilot projects in the Netherlands, which are regarded as the pioneer ones by international society, many CE-related practices are not implemented in pilot cases in Taiwan. To assist future project stakeholders to recognize what the key CE-related practices are and how they could be implemented in their building projects in Taiwan, this study has conducted a series of case studies of Dutch and Taiwanese pilot projects and semi-structured interviews with key project stakeholders of Taiwanese pilot projects. Thirty key CE-related practices are identified via case studies, along with their related 5R principles (Rethink, Reduce, Reuse, Repair, Recycle) and project phases. Suggestion on CE-related practices, their 5R principles, project items, and phases to implement in building projects in Taiwan is also proposed while discussion on differences between two countries’ pilot projects is presented.

The problem of creating effective models, methods and tools for strategic management of projects and programs for the development of organizations in the transition to a circular economy. Global trends in the development of organizations prove that the world is transforming with acceleration. The life cycle of knowledge and technologies for managing complex projects and programs is significantly reduced. The technical and technological complexity of organizational development projects increases due to innovations. These trends create significant challenges in the development of project management systems and programs for the formation of a circular economy in Ukraine. This is especially true of projects and programs in conditions of uncertainty about the impact of COVID 19 and anticipation of a global crisis after a pandemic. Today, the application of proven best practices (benchmarking) is no longer a way forward. Forming a vision, goals and strategy for the implementation of organizational development projects in advance makes our actions rigid, not flexible. When creating a project or program begins with focusing on what is valuable to our customers and the country, it is enough for us to use best practices. But the complexity and innovative orientation of development projects of organizations in the transition to a circular economy creates a number of challenges. One of the answers to these challenges is cost-effective work on project management and development programs, taking into account the trends of transition to a circular economy. Project management teams learn to distinguish between what is valuable and what doesn't matter, this is the path that management methodologies have taken for decades. A number of projects have taken the first steps in implementing the necessary cost-effective / flexible transition that supports sustainability and adaptability to turbulent environmental changes. In the conditions of modern destructive economic relations in the world community the problem of a choice of strategy of projects as drivers of development of the organizations is vital. One of the key approaches to the development of the EU is the transition to a circular economy with maximum utilization of both waste products and projects, and the disposal of project products after the end of product life cycles.

<p>Steel is the most recycled material in the world and a key contributor to the circular economy, but todays primary steelmaking methods result in high embodied carbon. In the face of the climate emergency, designers have been tasked with driving down the upfront emissions of the built environment. Naturally the embodied carbon characteristics of all materials have been put under the microscope and those with high impacts are being demonised, primary steel is one of those. So how does a designer balance the immediate needs of the climate emergency with the future needs of society? When confronted with a material like steel with practically perfect circularity characteristics but high embodied impacts how do designers balance the needs of today with those of tomorrow? What if steel could be made with zero carbon emissions? Coupled with its high potential for re-use and its high recycling rates is steel a friend and ally in the face of the climate emergency rather than a foe?</p>

The world ecological problem of waste accumulation, environmental pollution and the need to develop a circular economy are described. The aim of the article is to show the advantage of using a circular economy in the management of the national economy. It is substantiated that resource management should radically change from a linear model of accept-use-dispose to a more stable, circular model. It is proved that the principles of circular economy are not based on the management of material and waste flows, but on more valuable methods, such as maintenance, recycling and reuse. Different models of circular economy and their shortcomings are considered. Based on practical world experience in implementing the concept of circular economy, 5 main circular business models are identified. It has been established that circular supply chains that minimize waste and seek to reuse, repair and recycle where waste cannot be prevented should be more sustainable than the linear systems they replace. It was found that in the absence of effective resource management, the current environmental situation will lead to fatal consequences, which confirms the need for public administration to ensure the use of a circular economy.

The world is presently facing a climate catastrophe of its own making through the unabated increase in greenhouse gas emissions. Global consumption patterns are to blame, as presently, the global annual demand for resources outpaces the annual rate of the earth's ability to regenerate those resources. Thus, there is an urgent need to reduce the global demand for resources to a sustainable level, through the adoption of a circular economy. Individual consumption behavior habits form the basis of global consumption patterns, and therefore, adoption of sustainable consumption habits and lifestyles are necessary for addressing the climate crisis. In this chapter, the authors assess the potential for addressing the climate crisis through the adoption of a circular economy and sustainable consumption behavior. The authors also evaluate the extent of adoption of sustainable consumption behavior in India and make recommendations for adopting a circular economy in India.


This chapter will delve on modern approaches to city making (eco-cities, sustainable cities, resilient cities, etc.) explaining their basics and complexity. Additionally, the demands that changing solutions place on the architects, urban planners, and other city designers will be explained. The scope should be treated as the introduction to the circular economy approach; it will also cover other development attitudes where a city was not the initial prime element even if urban planning became one of the main issues during later phases of development. Such attitudes can be traced in the mid-20th century policy making with the car transport being the leading development attitude but having a wide impact on the solutions used in most cities. It will also explain when the urbanization process became part of this economic approach. The chapter will include principles of the modern initiatives in various parts of the world and consider existing movements allowing for a more sweeping coverage.
