Carbon‐based materials from renewable sources: Challenges and perspectives with a focus on green coconut

Abstract This article presents a comprehensive examination of agricultural production, biomass generation, and its transformation into biochar, with a particular emphasis on green coconut waste as a primary resource. It underscores the link between agriculture and substantial biomass output, shedding light on the ecological issues associated with solid waste. Furthermore, it highlights the significance of sustainable approaches. The article explores different aspects of green coconut biomass, encompassing its chemical composition, covering the biomass‐to‐biochar conversion, and addressing production techniques and activation methods. In the context of biochar applications, the article scrutinizes the preparation procedures for green coconut utilization, emphasizing emerging trends and overlooked areas. It includes prior research conducted by our research group. In the section discussing future prospects, it emphasizes the relevance of proper selection of coconut waste as carbon precursors, while also considering the obstacles to widespread adoption. Lastly, it examines the potential of biochar within the framework of the circular economy, along with its role in fostering sustainable practices and managing biomass waste. © 2025 The Author(s).
