Food safety in a circular economy


Book Description

Agrifood systems require sustained growth to maintain food security for the global population, while facing unprecedented pressure from challenges of climate change and resource depletion. In this context, evaluating, holistically planning and transitioning to circularity will be critical to improve sustainability and face those challenges. While circular economy initiatives offer considerable promise in improving sustainability and increasing performance, these benefits are juxtaposed by the increasing evidence that contaminants, physical, microbiological or chemical, can get introduced, persist and potentially lead to unsafe food. Therefore, protecting food safety is key for the success of transitioning our current linear agrifood system to a more sustainable and circular one. This report provides a synthesis of current and emerging evidence of food safety risks in circular agrifood initiatives, with an aim to understand challenges and opportunities to manage and enhance food safety. Food safety has to be an equal performance indicator for any transition, requiring addressing data gaps, focusing research efforts and exploring opportunities for improving food safety outcomes. All parties in the agrifood system need to proactively do their part to ensure agrifood systems develop, by harnessing the innovation in this area, and at the same time produce safe food.




Handbook of Recycling


Book Description

Winner of the International Solid Waste Association's 2014 Publication Award, Handbook of Recycling is an authoritative review of the current state-of-the-art of recycling, reuse and reclamation processes commonly implemented today and how they interact with one another.

It also details various recycling technologies as well as recovery and collection techniques. To completely round out the picture of recycling, the book considers policy and economic implications, including the impact of recycling on energy use, sustainable development, and the environment. With contemporary recycling literature scattered across disparate, unconnected articles, this book is a crucial aid to students and researchers in a range of disciplines, from materials and environmental science to public policy studies. - Portrays recent and emerging technologies in metal recycling, by-product utilization and management of post-consumer waste - Uses life cycle analysis to show how to reclaim valuable resources from mineral and metallurgical wastes - Uses examples from current professional and industrial practice, with policy and economic implications




Challenges and Opportunities of Circular Economy in Agri-Food Sector


Book Description

Global population by 2050 is predicted to be over 9 billion and accordingly, the production systems will demolish about 140 billion tons per year of minerals, ores, fossil fuels and biomass, i.e., thrice of the current need, and the food production itself has to be doubled. Optimized resource usage, lifecycle management, and reduced carbon emission have become a priority for agri-food businesses today, and circular economy (CE) helps for a sustainable and flexible way to grow without exhausting primary materials, and it thinks beyond recycling and resource usage. The word CE best relates to the resource and efficiency management, 6Rs, closed-loop production systems, zero waste and lifecycle engineering, reduced overconsumption of resources and waste generation, enriched system redesign and business model innovation, thereby leading to sustainable development goals. In this light, the book calls for theoretical and empirically sound contributions that are focused on the different aspects of the circular economy, 6R’s, sustainable production and consumption, closed-loop systems, etc. in the agri-food sector.

This book, written by Walter Stahel, who is widely recognised as one of the key people who formulated the concept of the Circular Economy, is the perfect introduction for anyone wanting to quickly get up to speed with this vitally important topic for ensuring sustainable development. It sets out a new framework that refines the concept of a Circular Economy and how it can be applied at industrial levels. This concise book presents the key themes for busy managers and policymakers and some of the newest thinking on the topic of the Circular Economy from one of the leading thinkers in the field. Practical examples and case studies with real-life data are used to elucidate the ideas presented within the book.




Resource Recovery from Wastes


Book Description

The concept of a circular economy has been gaining increasing attention in recent years. Many of the sources of chemicals we have become reliant on are dwindling and the accumulation of waste products poses a serious environmental problem. By recovering resources from these waste materials, we can reduce our dependence on virgin feedstocks that may not be sustainable as well as reducing the quantity of material going to landfill sites. Incorporating different perspectives from a global authorship, this book aims to introduce systems thinking to the field of waste and resource management. The topics covered range from the use of biogeochemical processes in resource recovery to the application of engineered nanomaterials, with information relevant to both academia and industry. The broad range and cross-disciplinary nature of the topics in this book make it a valuable resource for those working in circular economy research, green chemistry and waste and resource management.




Circular Economy and Sustainability


Book Description

The concept of circular economy is based on strategies, practices, policies, and technologies to achieve principles related to reusing, recycling, redesigning, repurposing, remanufacturing, refurbishing, and recovering water, waste materials, and nutrients to preserve natural resources. It provides the necessary conditions to encourage economic and social actors to adopt strategies toward sustainability. However, the increasing complexity of sustainability aspects means that traditional engineering and management/economics alone cannot face the new challenes and reach the appropriate solutions. Thus, this book highlights the role of engineering and management in building a sustainable society by developing a circular economy that establishes and protects strong social and cultural structures based on cross-disciplinary knowledge and diverse skills. It includes theoretical justification, research studies, and case studies to provide researchers, practitioners, professionals, and policymakers the appropriate context to work together in promoting sustainability and circular economy thinking. Volume 1, Circular Economy and Sustainability: Management and Policy, discusses the content of circular economy principles and how they can be realized in the fields of economy, management, and policy. It gives an outline of the current status and perception of circular economy at the micro-, meso-, and macro-levels to provide a better understanding of its role to achieve sustainability. Volume 2, Circular Economy and Sustainability: Environmental Engineering, presents various technological and developmental tolls that emphasize the implementation of these principles in practice (micro-level). It demonstrates the necessity to establish a fundamental connection between sustainable engineering and circular economy. - Presents a novel approach linking circular economy concept to environmental engineering and management to promote sustainability goals in modern societies - Approaches the topic of production and consumption at both the micro- and macro-levels, integrating principles with practice - Offers a range of theoretical and foundational knowledge in addition to case studies that demonstrate the potential impact of circular economy principles on economic and societal progress
