Manual mass balance in Excel
Closure errors compound across the month. By the time an auditor finds them, the certificate window is already open and the export contract is at risk.

Mass balance, certifiable.
For the plants that turn waste plastic into European biofuel.
ISCC EU and RED II compliant traceability for industrial pyrolysis. Load-by-load chain of custody, automatic mass-balance closure, third-party C14 sign-off and immutable audit logs — built for plants exporting to refineries in Rotterdam, Antwerp and Genova.

§ 02 — The problem
Spreadsheets, lab PDFs and Word templates were never going to survive an ISCC audit.
Pyrolysis plants exporting to European refineries operate under one of the strictest sustainability regimes in the world. The tooling most plants run today was not built for it.
02C14 · email
C14 lab disconnected from operations
Sample IDs travel by email, results land in a PDF, and nobody can prove which lot was tested. The biogenic fraction floats in a parallel system.
03POS · rework
POS documents rebuilt by hand
Every shipment to a European refinery means re-keying tonnage, supplier and certificate references into a Word template. Each version is a new compliance liability.
§ 03 — The solution
One system from truck to refinery.
DFT replaces the spreadsheets, lab inboxes and Word templates with a single audit-grade record of every kilogram, from intake to export.
Feature · 01
Load-by-load chain of custody
Every truck that arrives is a structured record: timestamp, supplier, transport class, certificate, eRSV and POS reference. Searchable, exportable, immutable.
· CAR · TRUCK · SPECIAL· eRSV linked· POS attached
Feature · 02
Automatic mass-balance closure
Daily production splits into EU PROD, PLUS PROD, Carbon Black, Metal scrap, H₂O, Gas/Syngas and losses. Monthly and annual closure runs against a configurable tolerance — alerts fire before the auditor arrives.
· Closure tol. 0.5%· Drill-down enabled· YE & monthly
Feature · 03
Third-party C14 sign-off
Saybolt NL — or any accredited lab — uploads results directly against the lot. Only certifier accounts can mark a batch as verified. No more PDFs in inboxes.
· Saybolt NL ready· Multi-lab capable· Digital sign-off
Feature · 04
Append-only audit log
Every certified record is hash-chained. POS documents are immutable post-signature. Operators cannot edit history; auditors cannot doubt it.
· SHA-256 chain· No UPDATE / DELETE· ISCC ready
§ 04 — Compliance
Built to stand up to the certifier in the room.
Schema, audit log and document model are designed against the ISCC EU System Document 205 and Directive 2018/2001. Closure tolerance, retention and signature workflows are configured in code, not in policy memos.

§ 06 — Case study
Girardot · Cundinamarca · CO
Eight million kilograms of mixed plastic. One ledger.
The BiNova plant in Girardot, Colombia, processes mixed plastic waste into pyrolytic oil destined for European refineries. In year-end 2024, every load, every production batch and every gram exported was reconciled against the ISCC mass-balance.

§ 07 — Engagement
Priced per plant, not per user.
Operators, certifiers and refinery viewers come and go. Your license tracks the asset, not the headcount. Final figures depend on volume, lab partners and deployment topology — we put numbers on the table after a 30-minute scoping call.
