Organic Waste Composting Through Nexus Thinking

Organic waste composting is another excellent example to demonstrate the power and the benefits of nexus thinking. Even though organic waste composting itself is not a new topic, those who want to start a new project or align an ongoing project with nexus thinking, find it difficult to gather the necessary information. With nine case studies from four continents, this book aims to fill above gap in literature. While current literature on composting is often found to be limited to either soil/agriculture sector or waste management sector, this book presents a combined point of view. This open access book starts with an introductory chapter that describes the need to bring the waste management aspects and soil nutrient management aspects of compost production into one integrated theme. The relevance of nexus thinking and the Sustainable Development Goals (SDGs) are also presented in this introduction. The first three chapters after the introduction covers composting from the solid waste management and its policy aspects, taking examples from three developing countries. The next three examples are mostly about the benefits composting can provide to the soil and agriculture. These examples are also from three developing countries, but with a mixture of urban as well as rural settings. Last three chapters present more insight into the latest developments taking examples from Europe, as well as new methods adapted from the traditional styles from Africa.

This book elaborates how water, soil, and waste may be managed in a nexus and how this approach may help combat global change. In addition to providing a brief account on nexus thinking and how it may help us tackle issues important to the world community such as food security, the book presents the environmental resource perspective of three main aspects of global change: climate change, urbanization, and population growth. Taking as its point of departure the thematic discussions of the Dresden Nexus Conference (DNC 2015) held in March 2015, the book presents the perspectives of a number of thought leaders on how the nexus approach could contribute to sustainable environmental resource management. The first chapter provides an introduction to the issues and consent of the book. Chapters 2 and 3 focus on climate change adaptation. Chapters 4 and 5 discuss the role of urbanization as a main driver of global change. The last two chapters of the book present ideas on how the nexus approach may be used to cope with population growth and increased demand for resources.

Humans generate millions of tons of waste every day. This waste is rich in water, nutrients, energy and organic compounds. Yet waste is not being managed in a way that permits us to derive value from its reuse, whilst millions of farmers struggle with depleted soils and lack of water. This book shows how Resource Recovery and Reuse (RRR) could create livelihoods, enhance food security, support green economies, reduce waste and contribute to cost recovery in the sanitation chain. While many RRR projects fully depend on subsidies and hardly survive their pilot phase, hopeful signs of viable approaches to RRR are emerging around the globe including low- and middle-income countries. These enterprises or projects are tapping into entrepreneurial initiatives and public ̶ private partnerships, leveraging private capital to help realize commercial or social value, shifting the focus from treatment for waste disposal to treatment of waste as a valuable resource for safe reuse. The book provides a compendium of business options for energy, nutrients and water recovery via 24 innovative business models based on an in-depth analysis of over 60 empirical cases, of which 47 from around the world are described and evaluated in a systematic way. The focus is on organic municipal, agro-industrial and food waste, including fecal sludge, supporting a diverse range of business models with potential for large-scale out-and up-scaling.

The fourth Factor X publication from the German Environment Agency (Umweltbundesamt, UBA), Sustainable Development and Resource Productivity: The Nexus Approaches explores the interdependencies of sustainable development paths and associated resource requirements, describing and analysing the necessities for a more resource efficient world. The use of and competition for increasingly scarce resources are growing worldwide with current production and consumption patterns of industrialised economies soon to reach the point where the ecosphere will be overtaxed far beyond its limits. Against this background, this volume examines the important initiatives to monitor resource use at the international, EU and national level. The current trends and challenges related to sustainable resource use are discussed, including international challenges for a resource efficient world, megatrends, justice and equitable access to resources. In the second part of the book, contributions examine implementation strategies. They assess the concept known as circular economy and discuss the theory of growth and the role of the financial and education systems. The final section places special emphasis on practical examples. Overall, the book presents concrete ways and examples of achieving more sustainability in practice. Discussing solutions for a more sustainable use of natural resources, this book is essential reading for scholars and students of natural resources and sustainable development and decision-makers and experts from the fields of policy development, industry and civil society.

By covering both the general principles of bioconversion and the specific characteristics of the main groups of waste materials amenable to bioconversion methods, this new book provides the chemical, biochemical, agrochemical and process engineer with clear guidance on the use of these methods in devising a solution to the problem of industrial waste products.

This book offers a broad and global level description of the current status of wastewater use in agriculture and then brings the readers to various places in the MENA Region and Europe to explain how some countries and regions have addressed the challenges during implementation. On a global scale, over 20 million hectares of agricultural land are irrigated using wastewater. This is one good, and perhaps the most prominent, example of the safe use potential of wastewater. Water scarcity and the cost of energy and fertilisers are among the main factors driving millions of farmers and other entrepreneurs to make use of wastewater. In order to address the technical, institutional, and policy challenges of safe water reuse, developing countries and countries in transition need clear institutional arrangements and more skilled human resources, with a sound understanding of the opportunities and potential risks of wastewater use. Stakeholders in wastewater irrigation who need to implement from scratch or improve current conditions, find it difficult to gather the necessary information on practical implementation aspects. The main objective of this book is to bridge that gap.

This book explores how integrated management of environmental resources via a nexus approach can help in achieving the respective Sustainable Development Goals (SDGs). It provides conceptual considerations but mainly practical examples on how to implement a nexus approach in cities and multifunctional land-use systems to increase resource use efficiency and develop a low carbon economy. After sketching out the background and conceptual outline, contributions to the book explore key aspects of the nexus implementation. Specifically, they • Demonstrate how to sustainably use organic waste and wastewater for agriculture, • Explore examples on how to manage multifunctional land-use systems including multipurpose reservoirs, • Highlight the importance of economic incentives for successful nexus implementation, and • Provide a comprehensive perspective on challenges and opportunities of implementation, considering peer-to-peer learning, indigenous knowledge, and stakeholder participation. The chapters in this book shed a new light on key aspects of the interrelation between SDGs and the nexus approach in resilient cities and multifunctional land-use systems, and provide specific examples on how to advance sustainable resources management.

The book’s primary intention is to serve as a roadmap for professionals working in developing countries interested in the Nexus Water-Energy-Food-Ecosystems (WEFE) approach. The book shows a multi-disciplinary approach, showcasing the importance of the proper use of Nexus WEFE when implementing certain development programs in regions around the globe. It can be presented as a manual for an individual that either wishes to implement intervention projects following the NEXUS approach or students interested in cooperation and development. The book begins with a general explanation of the theoretical concepts and implementation processes of Nexus WEFE and continues getting into case studies, explaining the importance of proper implementation and potential drawbacks and solutions to them. This book has a particular focus on the European Union cooperation policies when implementing such an approach in developing countries.
