Biojet Fuel: Current Technology and Future Prospect (Clean Energy Production Technologies)

by Arindam Kuila

This book covers the basic knowledge of biojet fuel, explores the current technological status, and presents future prospects for commercial biojet fuel production. The focus of this book is on biojet fuel production from different types of potential substrates. It also includes technoeconomic analysis and life cycle assessment of biojet fuel. Biojet fuel is currently recognized as the best alternative to petroleum-based jet fuel due to its renewability and sustainable features. However, there is a scarcity of reports on biojet fuel production from various types of substrates.The aviation industry globally consumes approximately 200 million tonnes of jet fuels each year, with a projected continuous growth rate of 5% per year until 2050 (Seymour et al., 2020). Currently, the global demand for jet fuel is predominantly met by petroleum-based fuels. However, the limited availability of fossil fuels and increasing concerns about climate change have placed significant pressure on commercial airlines to reduce greenhouse gas emissions and embrace cleaner and more sustainable practices.Biojet fuel has emerged as the most favorable alternative to petroleum-based jet fuel due to its renewable nature and sustainable characteristics. Despite its potential, there is a limited number of reports available on the production of biojet fuel from different types of substrates. The present scenario of biojet fuel necessitates the development of improved and cost-effective technologies that can yield long-term benefits.The book is useful for students and researchers in various branches of life sciences, including environmental biotechnology, bioprocess engineering, renewable energy, chemical engineering, nanotechnology, biotechnology, microbiology, and more.

Rainfed Agriculture and Watershed Management

by Sohan Singh Walia Karmjeet Kaur Tamanpreet Kaur

This book provides a comprehensive explanation of rainfed farming, dryland agriculture, and watershed management concepts. Despite utilizing all available water resources for irrigation, approximately half of the cultivated land will still rely on rainfall. With limited scope for expanding cultivated areas, meeting future food demands becomes an immense challenge. It is within this context that the significance of dryland agriculture emerges.Indian agriculture relies heavily on the monsoon, making water crucial for sustainable development. Unequal distribution of the global average rainfall (about 1000 mm) contributes to disparities in agriculture and socio-economic conditions. Around 70% of India's agriculture depends on rainfall, producing nearly 44% of the food and supporting 40% of the human and 60% of the livestock population. Even with full irrigation potential, half of cultivated land still relies on rain. Approximately 30% of the country is prone to drought and water scarcity, posing challenges for rainfed agriculture. Inefficient water use affects other inputs, emphasizing the need for resource management and indigenous systems.This book serves as a valuable resource for farmers, students, and scholars by providing guidance on various aspects of rainfed agriculture, dryland farming, and watershed resource management techniques. It aims to optimize the use of irrigation water and foster sustainable agricultural development. Additionally, it caters to the needs of graduate and postgraduate students studying agriculture, offering specific insights relevant to their designated course on rainfed agriculture and watershed management.

Paddy Straw Waste for Biorefinery Applications (Clean Energy Production Technologies)

by Neha Srivastava Bhawna Verma P. K. Mishra

This book provides an exclusive and critical in-depth analysis of paddy straw waste valorization at a broad scale for different industrial applications. It explores and discusses the various valorization pathways of paddy straw into valuable products connected to biorefineries' products and byproducts. The book also examines the scope, potential, and availability of paddy straw in the field of biorefineries. Various lignocellulosic biomasses with expanded potential are known for their industrial applications, even at a broad pilot range. Among these biomasses, paddy straw has emerged as the most suitable lignocellulosic waste for various biorefinery applications. Paddy is a crucial and widely consumed crop globally, and it generates the highest annual production of waste compared to other cereal crops. The cellulose content, accounting for approximately 47% of the total cellulosic biomass, offers significant potential for valorization, along with hemicellulose and lignin, which can also be explored and expanded on an industrial scale. However, despite the tremendous scope for valorization, lignocellulosic biomass-based biorefineries face cost-effectiveness challenges that need to be addressed for sustainable and uniform expansion, distribution, and economic scalability in various applications. The book's specific feature lies in its targeted and specific valorization of paddy straw into biofuels and other biorefinery-based products, which hold promising industrial applications and easily scalable approaches for mass production. This book is an essential resource for students, scientists, engineers and practitioners working in the biorefinery industry and academia.

Climate Change Impacts on Soil-Plant-Atmosphere Continuum (Advances in Global Change Research #78)

by Himanshu Pathak Dibyendu Chatterjee Saurav Saha Bappa Das

This book explores the interaction between climate change phenomena and the soil–plant–atmosphere continuum (SPAC), which inspects the crucial role of anthropogenic greenhouse gas emissions in modifying the net ecosystem response towards the modified environment. Increasing concentration of anthropogenic greenhouse gases (carbon dioxide, methane and nitrous oxide) from massive deforestation, fossil fuel burning and rapid industrialization in the post-nineteenth century have led to adverse changes in our global climate system. The book evaluates the net impact of climate change on soil, plants and the atmosphere individually and in totality. Among the topics it covers are the impact of climate change on soil environment which encompasses soil processes, nutrient cycling, soil carbon sequestration, soil biota response and soil health management. Also included are the impact on plants with respect to the dry matter assimilation pattern, modification in resource use efficiency, rhizosphere interactions, management of biotic and abiotic stress factors, and regulatory mechanisms of biotic stress factors in modifying the net agroecosystem response towards climate change. Moreover, potential genetic engineering options for establishing C4 or Crassulacean acid metabolism (CAM) in C3 plants, heat–drought stress on pollen biology, breeding ideotype, ecological indicators and crop simulation modelling are considered. Lastly, the impact on the atmosphere takes into account greenhouse gas measurements, mitigation options, eddy covariance measurement of greenhouse gasses, satellite-based monitoring, ecosystem services, abiotic stress management options, air pollution and atmospheric modelling. This book is a valuable resource for researchers, students and policymakers in understanding climate change impacts on interaction processes among the atmosphere, soil and plants from the local to regional scales.
