The Role of Biochar in Sustainable Agriculture
(Springer Science+Business Media, 2025) Manoj N. Shrivastava; Renu Singh; S. Srivastava
Biochar, a carbonized biomass derived from sustainable sources, offers significant potential for improving soil fertility and mitigating climate change. This chapter explores biochar production from urban waste, focusing on its agricultural applications. Urban waste, particularly municipal solid waste, presents a viable feedstock due to its abundant organic and inorganic components. The chapter details the pyrolysis process, a critical method for biochar production, highlighting its efficiency and environmental benefits. Biochar’s porous nature enhances soil water retention, nutrient availability, and microbial activity, thus improving crop yields and quality. Furthermore, biochar sequesters carbon, reduces greenhouse gas emissions, and decreases reliance on chemical fertilizers. Traditional and modern biochar production techniques are reviewed, emphasizing optimizing conditions to maximize yield and quality upon agricultural use. Challenges such as lack of awareness, technical barriers, and environmental concerns are discussed alongside potential solutions. The chapter underscores biochar’s role in sustainable agriculture, especially in developing countries, where it can contribute to food security, reduce deforestation, and promote cleaner cooking practices. Integrating biochar systems into agricultural practices can realize significant environmental, economic, and social benefits. © 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
