The authors and editors of this volume state that with the intensive growth of global industrialization and urbanization, the consumption of various resources and materials, such as energy, minerals, and even water, is increasing at an amazing speed, which poses great pressure on material resources. In addition, the massive utilization of materials has led to low efficiency, resulting in great wastes of resources as well as serious environmental pollutions and degradation, which has severely hindered the sustainable development of economy and society. In order to transit to sustainable development, it is necessary to improved resource efficiency, and circular economy and waste valorization are the best alternative ways for achieving this goal. This book aims to provide an in-depth description of circular economy and waste valorization, make assessments for circular economy and waste valorization in different regions and countries and determine the technological pathways and roadmap for achieving circular economy and waste valorization. More specifically: (1) Conceptions and Theories: Concepts and definitions of circular economy and waste valorization and their nexus and contributions to sustainable development. (2) Policy and Practice: Measurement and assessment of performance or sustainability for implementing circular economy and waste valorization. (3) Pathways and Prospects: Identification and prioritization of the barriers, strategies, technologies, and pathways for achieving circular economy and waste valorization. The book systematically and comprehensively introduces the definitions, concepts, framework and nexus of circular economy and waste valorization, analyzes and measures their performance and sustainability and provides the methods for investigating and prioritizing the barriers and strategies and determining the pathways and roadmap for their development.

This book adds a new dimension to the sustainability assessment of food waste reduction and valorisation: policy analysis. Featuring a transdisciplinary analysis by key experts in the field, it identifies the drivers of change in food-waste reduction and valorisation technologies by looking, for example, at the regulatory framework and at policy actions undertaken by local and global actors. The book explores the development of regulations and policies for food-waste prevention, management, and valorisation at a global as well as European Union level. It also discusses the notion of food waste in legal terms and investigates the effects of the lack of a standard, universal definition of food waste on the efficient use of by-products, promising processes and products for technological and commercial exploitation. Utilising mathematical mapping methods to assess food consumption impacts and providing supply chain models that allow the testing of consumption scenarios, the book goes on to discuss a series of emerging technologies (tested at lab scale and/ or pilot scale) and opportunities for the valorisation of food waste.

From Waste to Value investigates how streams of organic waste and residues can be transformed into valuable products, to foster a transition towards a sustainable and circular bioeconomy. The studies are carried out within a cross-disciplinary framework, drawing on a diverse set of theoretical approaches and defining different valorisation pathways. Organic waste streams from households and industry are becoming a valuable resource in today’s economies. Substances that have long represented a cost to companies and a burden for society are now becoming an asset. Waste products, such as leftover food, forest residues and animal carcasses, can be turned into valuable products such as biomaterials, biochemicals and biopharmaceuticals. Exploiting these waste resources is challenging, however. It requires that companies develop new technologies and that public authorities introduce new regulation and governance models. This book helps policy-makers govern and regulate bio-based industries, and helps industry actors to identify and exploit new opportunities in the circular bioeconomy. Moreover, it provides important insights for all students and scholars concerned with renewable energy, sustainable development and climate change.

In concomitance with the growing developments around the circular economy concept in the region, the resource recovery and recycling of industrial production residues is increasingly being envisaged in the European Union and its member states. The role of the recycling industry has become ever important in this context. The shredding industry is based on shredding discarded products such as end-of-life vehicles, and municipal white goods, and subsequent retrieval of (primarily) metals. Shredder fines (or fines) is a heterogeneous fine-granular production residue of this industry, which is currently disposed of. Shredder fines presents, and will continue to do so in the foreseeable future, several challenges that need to be addressed. It creates a disposal problem given the shrinking landfill availability and incurs handling costs to the shredding industry. Furthermore, it reduces our resources efficiency in general. This thesis aims to contribute knowledge on the challenges of facilitating the valorisation of shredder fines in the context of Sweden. In doing so, the current situation concerning fines and its management was investigated by addressing the research questions; 1) What is the resource potential of fines generated at the studied shredding plant, and 2) Why is the current disposal-oriented management of shredder fines sustained in Sweden. There, a systems perspective was employed, where the research questions were addressed on the material, actor, and institution levels, based on three scientific articles, which are appended. The studied material carries a certain amount of potentially recoverable resources, nevertheless shows a significant need for upgrading pertaining to the user requirements and regulatory standards of different recovery applications. The full recovery of fines requires integrated processes that could simultaneously harness these resource opportunities and resolve the material constraints. When it comes to the current practice of managing fines in Sweden, the utilisation in landfill covering offers the shredding companies a secure outlet for the material, given it is a well-established practice that has evolved over decades of operations and there is still a significant demand for landfill cover materials. Additionally, it provides shredding companies with a legislatively-compliant low-cost disposal option for managing fines. On the other hand, the complex materiality, lack of marketability of secondary raw materials (SRMs), and unfavourable governmental regulation of waste recovery create strategic disincentives for shredding companies in opting for fines valorisation. Fines valorisation calls for change in the well-established current practice of utilising the material in landfill covering. Thus, drastic policy measures such as phasing out landfilling and mandating resource recovery and recycling of fines are required to remove the incentives for fines disposal and compel the shredding industry to seek valorisation alternatives for its management. In order to ensure long-term sustenance, applications based on fines valorisation need favourable and more predictable circumstances and settings on different societal levels. There, secure outlets for potential fines-derived SRMs is one of the essential elements. Governmental interventions to create demand and alleviate valorisation investments via market and financial instruments play a significant role in that regard. The other primary requirement to facilitate fines valorisation in the long term is to set clear market and regulatory playing rules. Established supply and demand structures would enable clear pricing mechanisms for fines-derived SRMs and accurate economic assessments of fines valorisation, thus reducing the investment risk for shredding companies. On the other hand, clear regulatory standards and favourable regulatory practices would reduce the uncertainty of the realisation of valorisation applications and gain trust among actors.

The book is designed to help public and private decision-makers and academics deepen their knowledge and understanding of the contexts, obstacles and challenges of a variety of business types involved in Industrial Symbiosis and Circular Economy practices. Industrial Symbiosis is reported in the Action Plan on the Circular Economy developed by the European Commission in 2015 (COM / 2015/0614 final) and in its revision of 14 March 2017, but relatively little is known of how these practices start, develop or fail, and mutate in a rapidly changing context. Including selected contributions presented at the 24th ISDRS 2018 Conference, “Actions for a Sustainable World: from theory to practice” in the two theme tracks “5c. Circular economy, zero waste & innovation” and “5g. Industrial symbiosis, networking and cooperation as part of industrial ecology”, this book offers a transdisciplinary perspective on real experiences of industrial symbiosis, performed both by industries and the scientific community, best practices, success and unsuccessful cases (implemented or under implementation), with the final aim to promote the adoption of Industrial Symbiosis as an operational and systematic tool for the Circular Economy. In particular, a focus on the environmental, social, and economic impact of Circular Economy and Industrial Symbiosis practices, and how those impacts may be context and/or scale dependent is given.
