**7. Conclusions**

The utilization of activated carbon derived from biomass in gases and aqueous solutions has grown significantly in various industrial applications. However, due to its high cost and nonrenewable sourcing, alternative sources of these carbons are being sought after. This review highlights biomass as a resource, the structure of biomass, and the production methods for activated carbon using biomass materials, as well as various carbonization and activation techniques. Activated carbon has demonstrated great potential in water treatment, often surpassing commercial carbons, depending on the target contaminant. While activated carbons have been extensively studied, there is a lack of research on how different production methods affect their use in continuous bed columns and regeneration potential. Biomass materials' composition varies depending on origin and agronomic practices, necessitating more detailed studies on the production, optimization, and application of biomass-based activated carbon.
