Biomass Asia is in Carbonfuture's supplier due-diligence, with Puro.earth onboarding in tandem. Credits are issued as CORCs on a “land-and-expand” basis — spot sales first, then offtake.

Every batch tracked

The 6-step biochar lifecycle

Rice-husk & straw sourcing→Pyrolysis→Packaging (weighed / sampled)→On-site storage→Transport→End use — permanent storage

Integrity

We pre-answer the hard questions

Additionality

Biochar-only is near break-even; carbon revenue is the enabler — the project wouldn't happen otherwise.

Permanence

CORC200+ — carbon stable in soil for 200+ years, evidenced by lab analysis.

Leakage & over-crediting

Conservative factors, chain-of-custody tracking and independent verification.
