"High-caloric coconut shell charcoal. Engineered for extreme purity, smokeless combustion, and minimal ash residue."
"Sourced strictly from natural coconut shell husks. Zero timber deforestation, carbon-neutral manufacturing process."
"7,500 kcal/kg calorific value guarantees prolonged, steady thermal output for industrial and hospitality demands."
"Rigorously tested batch by batch for fixed carbon (>80–85%), minimal moisture (<8%), and minimal ash (<3–5%)."
COCONUT SHELL
CARBON MATRIX.
SUNA Charcoal is a coconut-shell-based charcoal product developed for applications that require a consistent, efficient, and high-heat carbon source. Produced from natural coconut shell raw material, the product is intended to provide reliable burning performance with relatively low smoke generation and low ash formation.
Its characteristics make SUNA Charcoal suitable for both industrial applications and commercial heating requirements, depending on the selected grade and intended use.
PERFORMANCE
PARAMETERS.
SUNA Charcoal is characterized by the following specified performance parameters:
Fixed Carbon
High-purity elemental carbon content supporting sustained combustion and minimal non-combustible residue.
Calorific Value
Exceptional heat-generating capacity providing steady radiant thermal energy.
Moisture Content
Controlled low moisture level preventing heat loss during ignition.
Ash Content
Extremely low ash-forming material ensuring clean burning operations.
Volatile Matter
Low volatile components resulting in clean, virtually smokeless performance.
These specifications describe the carbon content, moisture level, ash-forming material, volatile components, and heat-generating capacity of the product. The combination of these properties supports applications where a relatively high-carbon and efficient solid fuel or carbon source is required.

Direct Technical Answers
Charcoal Specifications & Export FAQ
Direct answers regarding our coconut shell carbonization, activation feedstock metrics, and bulk logistics.
01What are the core technical specifications of SUNA coconut shell charcoal?▼
SUNA coconut shell charcoal delivers 80%–85%+ fixed carbon, gross calorific value of 7,000–7,500 kcal/kg, total moisture <7%, and non-combustible ash content under 3.0%. All specifications are validated by ASTM laboratory assays and pre-shipment SGS certificates.
02Is SUNA charcoal suitable as feedstock for activated carbon activation?▼
Yes. Our industrial granulated charcoal (3x6, 4x8, and 8x30 mesh) is specifically manufactured from mature Sri Lankan coconut shells, providing the high mechanical hardness, uniform micro-pore density, and low ash essential for high-yield steam activation in water filtration, gold recovery (CIP/CIL), and air purification.
03What packaging formats and container capacities are available?▼
We provide 25kg PP woven bags with polyethylene liners, 500kg/1,000kg UV-resistant Jumbo Super Sacks, and 1kg/10kg OEM master cartons. A standard 40ft High Cube (HQ) ocean container accommodates approximately 18.5 Metric Tons on heat-treated ISPM-15 pallets or up to 24 Metric Tons floor-loaded.
04What is the combustion duration and smoke profile of the briquettes?▼
SUNA extruded hexagonal briquettes burn for 4.5 to 6.0 hours with steady radiant heat, producing zero toxic smoke, zero chemical smell, and no sparks. They burn completely to a natural light-grey ash residue of less than 3%.
