Section 7.2: the molar H/Corg ratio must be less than 0.7, and less than 0.4 for EBC-FeedPlus.
Section 7.3: the molar O/Corg ratio should be below 0.4. The same section says the ratio can exceed 0.4 and that Carbon Standards International may then carry out a plausibility check. This sheet records that as an aim.
Section 7.5 and Table 2: heavy-metal limits. The text states that EBC-Urban and EBC-Materials must meet the same heavy-metal limits as EBC-Agro, and that EBC-Basic has no heavy-metal limit, only a declaration.
Biochar Trade is not Carbon Standards International and does not issue an EBC certificate.
