Sri Lanka is globally recognized for high‑quality coconut‑shell activated carbon, benefiting from its strong coconut industry and established expertise in charring and steam activation. Coconut‑shell activated carbon produced in Sri Lanka is prized for high density, low dust, high hardness, and very low levels of sulfur and arsenic, making it ideal for potable water, food, and sensitive industrial applications.[11][6][2]
The core raw material for most Sri Lankan Activated Carbon Manufacturers and Suppliers is coconut shell, a by‑product of coconut oil and desiccated coconut production. Shell charcoal is produced via controlled carbonization, followed by steam activation in vertical or rotary furnaces to develop micro‑ and mesoporous structures suitable for adsorption of organics, chlorine, VOCs, and odours.[11][6][2]
Some producers also experiment with rice husks, wood, and other biomass sources, but coconut shell remains the dominant base due to its high fixed‑carbon content and favourable porous structure after activation. Environmental initiatives, such as “green charcoaling” and energy‑recovery systems, help reduce emissions and improve sustainability across the Sri Lankan activated carbon value chain.[5][6][2]
