Certification Statement

The “Inertinite Gold Certificate” is awarded to biochars in which ≥ 95 % of the organic carbon is classified as inertinite and the mean random reflectance (Ro) ≥ 3 %. Inertinite represents the most stable form of organic carbon in the environment, exhibiting resilience comparable to that of inorganic minerals and ensuring long-term carbon storage (1).

Disclaimer

  • Certification is valid for three (3) months from the submission date.
  • These findings apply only to the submitted sample(s), as provided by the Client or a designated third party. Fusinite Ltd assumes no responsibility for the declared origin or representativity of the material.
  • The values reported in this certificate do not account for batch or production variability. Assessment of such variability requires systematic sampling and analysis over a defined period.
  • The analytical uncertainty is generally within a relative standard error (RSE) of ≤ 10%.
  • Carbon and hydrogen contents were analyzed according to ISO 29541:2010. The Inertinite Benchmarking (IBRo2) includes Random Reflectance Analysis (Ro), following Sanei et al. (2025)(2), the ITPE Procedure, and ISO 7404-5:2009, together with reactive organic carbon and mineral carbon analysis using the Rock-Eval 6 method. For the complete analytical protocol, see Sanei et al. (2025)(2).
