Quality Assurance

Quality at the Source

We are the only activated carbon plant in the world that manufactures its own charcoal. This unique approach allows us to control quality from the very first step of the process.

Our in-house quality control laboratory tests every batch to ensure compliance with international standards including ASTM, AWWA, NSF, and EN specifications.

Our Process

Quality Control Steps

  1. We buy local coconut shells, avoiding imported raw materials with uncertain quality.
  2. The material is carefully inspected to remove waste, stones, and foreign particles.
  3. The material is sun-dried to reduce moisture content below 10%.
  4. Raw shells are crushed, screened, and prepared for carbonization.
  5. Carbonization at 400-600 C, maintaining volatile matter at 15%.
  6. Carbon is washed and processed for steam activation.
  7. Every batch is tested in our in-house laboratory before shipping.
