How we make it
From biocharto packaged batch.
An industrial line engineered for continuous operation. Eight documented stages. Every parameter monitored, every batch certified, every change logged.
The process · at a glance
Thermal steam activation.
Input: biochar. Output: activated carbon with controlled pore distribution, batch-level traceability, and declared CO₂e. The line operates 24/7 with shift handovers. Every critical parameter is instrumented and logged in the quality system.
Stages
The process, step by step.
01
Reception
Biochar arrives at plant, is weighed, sampled and registered. We do not process a batch that does not pass inbound control.
02
Drying
Biochar is dried to 5–7% humidity under controlled conditions. Lower moisture stabilizes kiln feed and reduces downstream energy consumption.
03
Dosed feeding
Calibrated-screw feeding into the rotary kiln. Mass flow is monitored continuously to keep activation at steady state.
04
Steam activation
Rotary kiln at 800–950°C with superheated steam as activator. This is where biochar transforms into activated carbon with the target pore structure.
05
Cooling
Controlled cooldown under inert atmosphere prevents re-oxidation. Exit temperature ≤ 100°C before any further handling.
06
Milling & sieving
Particle size controlled per SKU. Granular grades pass calibrated screens; powdered grades pass hammer milling and 325-mesh classification.
07
QC laboratory
Every batch is tested in-house: iodine number, BET, ash, moisture, pH, hardness, apparent density. Every shipment leaves with a Certificate of Analysis.
08
Bagging
Packed in 25 kg paper bags with PE liner, 500/1000 kg FIBC, or ISO containers for bulk. Palletized and stretch-wrapped.
Quality assurance
Every batch ships with a Certificate of Analysis.
Each shipment includes a CoA with iodine, BET, ash, moisture, pH, hardness, and apparent density — plus the ISO 14067-aligned CO₂e declaration. Traceability runs from biochar batch to shipment, and test methods reference ASTM or ISO standards.
Per-batch CoA
Nine-parameter physical and chemical assay, signed by QA.
Full traceability
From biochar batch to final packaging, auditable by customer or third party.
Third-party testing
SGS · ALS · Bureau Veritas · on request or by framework contract.
CO₂e per tonne
ISO 14067-aligned methodology, declared next to the datasheet.
