The paper "Coconut Waste: Discovering Sustainable Approaches to Advance a Circular Economy" by Fabrícia Vieira et al. explores the environmental and economic challenges posed by the agro-industrial residue generated from coconut fruit processing. The authors highlight the potential of coconut waste, characterized by its lignocellulosic composition rich in lignin and multifunctional groups, to be transformed into valuable products and byproducts. The review covers the historical context of coconut economic exploration, its chemical composition, and diverse applications of coconut products. The paper emphasizes the importance of repurposing coconut waste to mitigate environmental impacts and promote a circular economy. It discusses the utilization of coconut residues in various sectors, including handicrafts, organic fertilizers, bioethanol, cementitious materials, bioadsorbents, and alternative solid fuels. The study also addresses the infrastructure and logistics challenges in integrating coconut residue valorization into the circular bioeconomy, advocating for sustainable practices and the economic and industrial reintegration of lignocellulosic biomass as a key raw material. The research method involves a comprehensive literature review, evaluating original research articles, reviews, and technical notes related to coconut industry aspects and agro-industrial residues. The paper provides a detailed overview of coconut history, cultivation, value chain, and the chemical composition of coconut residues, highlighting their potential in civil construction, filtering and adsorption materials, ethanol production, pyrolysis products, and other applications.The paper "Coconut Waste: Discovering Sustainable Approaches to Advance a Circular Economy" by Fabrícia Vieira et al. explores the environmental and economic challenges posed by the agro-industrial residue generated from coconut fruit processing.
