ReChar Methodology for Crop-Residue Gasification, Useful Heat, Fuel Displacement, Livestock Integration, and Biochar-to-Soil Outcomes

RC-CRG-POC-001Demonstration Version 2.0.0published

A gasifier does not create a digital asset. Completed and evidenced cycles may create measured conservation outcomes. Those outcomes become digital assets only after post-impact Proof of Conservation, independent technical validation, legal-sufficiency review, registrar determination, and Negatrope registration.

Demonstration Version 2.0. Lotus Fire Gasifier is the first qualified technology family, not the entire methodology name. Comparable gasifiers may be admitted after separate qualification. Digital assets arise only after post-impact PoC, validation, legal review, and registrar determination.

Controlling chain

Eligible biomass → qualified technology → commissioned unit → measured cycle → useful heat → evidenced counterfactual displacement → biochar batch → livestock pathway → organic-material batch → soil application → measured agricultural outcome → lifecycle deductions → PoC → validation → legal review → registrar → Negatrope → instrument

Do not create an unsupported composite impact score. Wood and LPG displacement are alternative, not additive, for the same heat.
