Abstract:
The coconut palm (Cocos nucifera L.), a globally significant tropical crop, underpins a rapidly expanding industry driven by surging demand for natural, plant-based products. With the coconut market projected to exceed USD 50 billion by 2030, sustainable management of processing residues-principally coconut shell and coir-has emerged as a critical bottleneck for the sector's high-quality development. This review systematically evaluates the potential of these lignocellulosic by-products as feedstocks for a circular bioeconomy, focusing on their physicochemical characteristics, global processing infrastructure, and valorization pathways. We construct a novel "waste-technology-product" mapping framework that integrates established and emerging conversion technologies, including advanced bioethanol production, thermochemical conversion, and functional material synthesis. Key applications span high-value functional filtration media, sustainable construction materials, bioactive ingredients for cosmetics and nutraceuticals, and environmental remediation agents. By synthesizing mechanistic insights into recalcitrance reduction, process intensification, and multi-product biorefining, this work provides a robust scientific foundation for enhancing resource efficiency and advancing waste-to-value chains in the coconut industry.
