Circular Economy Capabilities Toward Fly-Ash Management
No full textThis chapter explores the transformative potential of fly ash, a by-product of coal combustion, within the framework of a circular economy. With growing environmental concerns over waste management and resource depletion, fly ash is being reimagined as a valuable resource rather than merely industrial waste. This chapter outlines a comprehensive strategic framework for fly ash management, focusing on key areas such as regulatory advancements, technological innovations, sustainable transportation, and the role of public-private partnerships (PPPs). It also discusses how fly ash can contribute to green infrastructure, enhancing urban resilience and sustainability. This research highlights the urgent need for global cooperation to address the challenges associated with fly ash while proposing practical solutions that align with sustainability goals. By integrating fly ash into construction, water management, and soil reclamation, this chapter presents a pathway for industries and governments to reduce environmental impact and promote resource efficiency. This chapter provides a compelling argument for adopting circular economy principles in fly ash management and paves the way for future innovations in sustainable development. Readers interested in environmental sustainability, waste management, and green infrastructure will find valuable insights and strategic directions in this work
Introduction to Various Fly Ash (Coal & Bio-Coal) Generated from Industrial Operations
No full textThis chapter presents the intricate dynamics of fly ash, a byproduct of both coal and bio-coal combustion, which has gained renewed interest for its broad industrial applications. While often seen as mere waste, fly ash embodies distinct chemical properties that hold the potential for transforming conventional industrial processes. The discussion extends beyond typical uses, exploring innovative paths in sustainable applications and environmental management. The nuances in fly ash composition, driven by variations in feedstock and combustion processes, are explored to uncover its role in promoting a circular economy. By discussing the emerging applications of both coal and bio-coal fly ash (BFA), this chapter highlights the evolving relationship between industrial byproducts and sustainable practices. Through this lens, it opens new avenues for rethinking resource efficiency and environmental stewardship, thereby offering a fresh perspective on how fly ash can support more resilient and eco-friendly industrial systems
Circular Economy and Sustainable Management
No full textThis book summarizes both conventional and emerging waste management approaches for fly ash, particularly with a focus on sustainability dimension – including its applicability, scope, methods, and challenges of bio-coal production. It covers the sustainability aspects of fly ash management and recent developments in methods, processes, and scope of bio-coal production as an alternative to conventional coal along with its implications for industrial ecosystems.

Comprehensively covers all the dimensions related to coal and bio-coal fly ash and circular economy associated with it Discusses cradle-to-grave technology for bio-coal Emphasizes the efficient, economically viable, and environmentally sustainable use of coal and bio-coal fly ash Explores renewable fuel solutions and circular economy associated with it Encourages the use of bio-coal for boosting sustainability and circular economy This book is aimed at researchers and graduate students in environmental and civil engineering, as well as those working in clean technologies
Life Cycle Assessment and Cost Analysis of Fly Ash
No full textThis chapter reviews the environmental and industrial implications of fly ash (FA) produced from coal and biomass based power plants. We provide an outline of the types of FA used in industrial applications such as coal fly ash (CFA), rice husk ash (RHA), and bagasse ash (BA). We also discuss the environmental risks associated with improper disposal of FAs. This chapter also emphasizes the importance of the life cycle assessment (LCA) framework as a critical tool for identifying environmental hotspots and guiding sustainable practices in the management and utilization of FA. This chapter further discusses the application of FA in various sectors, including construction, embankments, landfilling, and adsorbents, assessing their potential to reduce carbon footprints and promote a circular economy. Finally, this chapter concludes with the need for innovative approaches to repurpose FAs, minimize their environmental impact, and enhance sustainability in industrial practices
Fly Ash-Based Sustainable Building Materials and Life Cycle Assessment of Fly Ash
No full textThe increased energy demands have placed enormous pressure on finite fossil fuels. These fossil fuels consumption has reached 15 billion million tonnes (MT) annually, which has contributed to 37.55 billion MT of carbon dioxide emissions in 2023. These emissions lead to global warming, climate change, and other associated changes. Therefore, there is a need for carbon sequestration for a better tomorrow. Fly ash (FA), a waste product generated by coal-fired electric and steam-generating plants is a potent waste that can be used for different practical uses. Moreover, it is estimated that around 500–600 MT of FA is generated annually. This waste can be tapped for resource recovery. In fact, FA is an emerging building material that can also contribute to carbon sequestration. This chapter explores FA-based bricks, concrete, and other building materials for sustainability. These materials require lesser cement and other natural resources. The produced materials with comparable strength, stability, and density could synergize with the conventional building materials and could be a small step towards sustainability with circular economy
Influence of Adult Education Program on Agricultural Wages: Moderating Effect of Village Size
No full textThis paper studies the influence of adult education program on to the prevalent agricultural wages in villages of India. Adult education program in India is conducted by various state governments irrespective of the consideration of village characteristics. We argue village characteristics as an important variable towards the success of any government program. The objective of any government program in villages is to improve the economic status of villagers. Prevalent agricultural wages are a good indicator of the economic well-being of rural inhabitants. Therefore, as an indicator of economic development of Indian rural population, we have selected agricultural wages as the dependent variable. In earlier studies, there are predominantly four significant determinants of agricultural wages. They are non-agricultural, transportation, regional, and local factors. After controlling for these factors, we have found that adult education has significant positive influence on the larger size of villages and in a smaller size of villages, it does not have any influence. We have used robust regression technique in our analysis due to the presence of outliers in the data
Impact of Energy Mix on Nitrous Oxide Emissions: An Environmental Kuznets Curve approach for APEC countries
No full textThere is a limited number of studies on the estimation of Environmental Kuznets Curve (EKC) hypothesis for Nitrous Oxide (N2O) emissions, though it is one of the most harmful greenhouse gases (GHGs) present in ambient atmosphere. In the wake of industrialization, it is necessary to understand the impact of energy consumption pattern on N2O emissions and revise the energy policies accordingly. In this study, we have analysed the impact of renewable and fossil fuel energy consumptions on N2O emissions for APEC countries over the period of 1990-2015, and the analysis has been carried out following the EKC hypothesis framework. The results obtained from the study indicate the efficacy of the renewable energy solutions in having positive impact on environmental quality by helping to reduce the level of N2O emissions. The policy implications derived the results are designed keeping the objectives of Sustainable Development Goals (SDGs) in mind, so that the energy policies can bring forth sustainability in the economic systems in these nations
