Coconut agriculture is considered an economical crop that is commonly cultivated in the tropics. Annually, approximately 300 million tonnes of coconut were produced globally. The coconut husk constitutes about 40% of the entire fruit and is generally incinerated or brought to landfills, which could further emit unwanted greenhouse gases. The main composition of CH comprises of polymeric compounds, namely, cellulose, hemicellulose and lignin. Here, we discuss systematic valorisation solutions to convert coconut husk into various functional materials. With delignification pre-treatment, the cellulose-rich coir was developed into high-performance plastic alternatives, nano-scaled reinforcement agents, fluorescence switchable fibers, and biochar-based electrode material for CO2RR. On the other hand, the separated lignin was functionalized and polymerized into various copolymers and processed into nanoparticles, nanofibers and hydrogels. Their potential applications in personal care and biomedicine were also investigated. We expect that this strategy can be extended to rationally design functional nature-based materials from various biomass sources.
