The circular economy is considered as an alternative model to the unsustainable linear ,Äútake,Äìmake,Äìwaste,Äù approach that characterizes contemporary economic systems. It aims to achieve sustainable development by promoting the responsible and cyclical use of resources to maintain their value in the economy and minimize pressures on the environment. Biochar systems offer opportunities for operationalizing the CE model. They are multifunctional systems that can be used for bioenergy and biochar production using an extensive range of biomass feedstocks, including biowaste. They can contribute to climate change mitigation, as producing biochar and mixing it with soil is a means for sequestering atmospheric CO2. Moreover, the produced biochar has a wide range of applications, including its use for agricultural soil amendment, wastewater treatment, manufacturing of cement, and remediation of contaminated soils. This versatility of biochar systems creates great opportunities for developing circular models of waste management that can valorize different waste streams. This chapter provides an overview of the CE concept and describes biochar systems, focusing on systems for the synergistic valorization of wood waste and contaminated soils. It also discusses the role of these systems in the CE indicating that they can contribute to the transition toward the CE.

Fully revised and updated for its third edition, this book presents the definitive compilation of current knowledge on all aspects of biochar. Research on biochar continues to accelerate as its importance for soil health, climate change mitigation and adoption, and the circular economy becomes more widely acknowledged. This book not only reviews recent advances made in our understanding of biochar properties, behavior, and effects in agriculture, environmental management, and material production, but specifically develops fundamental principles and frameworks of biochar science and application. This third edition has been fully revised and updated to reflect recent developments and growing trends, with important coverage of the application of biochar outside of its traditional soil-based uses, the commercialization of biochar, and its incorporation into policy. This includes brand new chapters on the role of biochar-based materials for environmental remediation, building construction, and animal feed, and a greater discussion of biochar's role in the circular economy, climate change mitigation, and sustainable development. Overall, this book provides a systematic, comprehensive, and global examination of biochar. Written by an international team of academics and professionals, it addresses its uses, production, and management and its broader potential for mitigating climate change and driving forward sustainable development. Edited by two leading figures in the field, Biochar for Environmental Management is essential reading for students, scholars, practitioners, and policymakers interested in biochar and the role it can play in environmental sustainability and global sustainable development.

Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.

Waste-to-Resource System Design for Low-Carbon Circular Economy equips the user with the necessary knowledge to carry out the preliminary design and optimization of economically viable and environmentally friendly waste-to-resource systems. This book covers the state-of-the-art development of technologies and processes in terms of six types of bioresources (i.e. energy, biohydrogen, biomethane, bioethanol, biodiesel, and biochar) that are recoverable from waste. The focused technologies and processes, such as anaerobic digestion, fermentation, pyrolysis, gasification, and transesterification are being widely applied—or have the potential to be used—towards sustainable waste management. It also covers the methods needed for the design and optimization of waste-to-resource systems, i.e., multiobjective optimization, cost-benefit analysis, and life cycle assessment, as well as systematic and representative databases on the parameters of the processes, costs, and the advantages and disadvantages of technologies.

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.
