Production Process
The quality is decided long before it reaches the packing floor.
Understanding how we produce is understanding why our product performs the way it does. Buyers who understand our process become long-term partners, not one-time importers.
Shell Sourcing and Collection
Only verified, post-agricultural shells enter our facility.
Coconut shells arrive at our facility from a network of agricultural processors, oil mills, and copra producers across Sri Lanka's major coconut regions. Every shell we receive is post-production waste from the food and oil industry. Nothing is harvested or cut for charcoal production.
Shells are inspected on arrival. Heavily contaminated, wet, or mixed shells are rejected. Only clean, dry, mature coconut shells enter our process. This first gate is where most producers cut corners. We do not.
Detail
Supplier verification conducted on-site. All suppliers are documented, visited, and required to confirm in writing that shells are post-agricultural waste only. No shells from land-clearing or forestry operations are accepted under any circumstances.Drying and Pre-Treatment
The invisible step that defines the final product.
Shells are sun-dried and then moved through our controlled drying stage to reduce moisture to the target level before carbonisation begins. Wet shells produce poor charcoal — low fixed carbon, high smoke, inconsistent output. Dry shells carbonise cleanly and efficiently.
This step is invisible in the final product but defines it completely. Producers who skip or rush this stage cannot produce consistent fixed carbon results regardless of how well their kilns are set up.
Detail
Moisture is measured at intake, after sun-drying, and before kiln loading. Only shells within our target moisture range enter the carbonisation stage.Carbonisation
Slow, controlled, and not rushed — this is where the transformation happens.
Shells are loaded into our industrial carbonisation kilns and fired under carefully controlled, oxygen-limited conditions. The process runs for an extended cycle. Temperature is managed throughout. This slow, controlled burn drives off volatile compounds completely and converts the organic carbon structure of the shell into a dense, stable charcoal with the high fixed carbon content our buyers require.
We do not use fast-burn open methods. We do not blend partially carbonised material to increase volume. Every batch completes its full cycle.
Detail
Oxygen-limited environment prevents uncontrolled combustion. Temperature curves are monitored and recorded per batch. No batch is ejected early to increase throughput.Cooling and Primary Sorting
Hot charcoal exposed to open air degrades. We do not allow that.
After carbonisation, material is cooled in sealed conditions before being moved to the sorting floor. Hot or partially cooled charcoal exposed to open air re-oxidises and degrades quality. Controlled cooling is non-negotiable in our facility.
On the sorting floor, under-carbonised material, oversized pieces, and foreign matter are manually removed before the batch proceeds to processing.
Detail
Cooling duration is set to allow full temperature normalisation before the batch is opened. Manual sorting is conducted under good light with trained sorters who have clear reject criteria.Crushing, Screening and Grading
What the screen passes is what goes in the bag — nothing else.
The carbonised shells are fed into our mechanical crushers and then passed through a series of precision screens to produce the specific size grades required — coarse lump, granules of various mesh sizes, or fines.
Our screening equipment is calibrated to produce consistent, uniform output. There is no dust mixed in to bulk out a shipment. There is no sand added to increase weight. What the screen passes is what goes in the bag — clean, graded charcoal and nothing else.
Custom screening is available for buyers with specific mesh or particle size requirements.
Detail
Screen calibration is checked and logged at the start of each production run. Custom mesh configurations are available and prepared to verified specifications before a buyer order is processed.Quality Testing
Every batch tested before packing. Failed batches do not ship.
Every batch is tested before packing. We measure fixed carbon percentage, ash content, moisture content, volatile matter, and particle size distribution. Results are recorded per batch.
Third-party laboratory testing is available and conducted regularly. Buyers receive a Certificate of Analysis with every shipment — not on request, as standard.
If a batch does not meet our internal specifications, it does not ship. It is reprocessed or used in lower-grade applications. We do not send a substandard batch with an apology and a discount.
Detail
Testing is conducted in-house per batch. Third-party laboratory verification through SGS or equivalent external lab is conducted on a scheduled basis and available on request for any specific shipment.Packing and Export Preparation
From our facility to your port — we manage the full process.
Approved batches are packed to buyer specification — jute bags, PP woven bags, or bulk containers. Bags are sealed, labelled, and palletised. Export documentation is prepared in parallel — phytosanitary certificates, SGS or third-party inspection, bill of lading, certificate of origin, and certificate of analysis.
We handle the full export process from our facility to your port. Colombo is one of the busiest and best-connected ports in the Indian Ocean. We use that advantage to give buyers reliable, competitive lead times and freight options.
Detail
Documentation is prepared and checked against shipment contents before loading. No shipment moves without a complete document set. Buyers receive copies digitally before vessel departure.Certificate of Analysis with every shipment. Not on request. Every time.
Results are recorded per batch. Buyers receive documentation before vessel departure. If it doesn't meet spec, it doesn't ship.
