Every Kilogram Must Be Real. Every Movement Must Be Proven.
At Astra Sage, traceability is not a slogan. It is the control system that protects public trust, prevents fraud, and keeps sustainability claims honest. We are building a UCO supply chain in which every approved Point of Origin, every collection, every batch, every transfer, and every sustainability claim is documented, auditable, and aligned with ISCC traceability and mass balance requirements.
| Why This Matters
Traceability Is What Protects the System
Used cooking oil has value because it is a genuine waste-derived feedstock. That value disappears if the market cannot prove that the oil was truly generated as waste, collected through a verified chain, and allocated correctly through mass balance bookkeeping. ISCC requires traceability and chain-of-custody controls across the supply chain so sustainability characteristics can be forwarded credibly and so operators cannot claim more certified product than they actually sourced.
Astra Sage’s own supplier code and fraud-control procedure already point in the right direction: only genuine UCO may enter the system; Points of Origin must be declared truthfully; self-declarations must be signed; collection events must be documented; and all inbound material must be assigned a batch ID and recorded into the mass balance ledger.
| What ISCC Mass Balance Means
What Is ISCC Mass Balance?
Under ISCC EU, mass balance is a chain-of-custody model that allows certified and non-certified material to be physically mixed, but only if the sustainability characteristics are kept separate in bookkeeping. In plain language: the tank may contain a physical mix, but the books must always show exactly how much certified material came in, how much is still in stock, and how much can lawfully be claimed on the way out. No operator may claim more certified output than certified input, and the balance must follow the real physical flow of material through the site.
Mass balance is not “trust me.” It is “show me the records.”
Technical note
ISCC also makes clear that Sustainability Declarations can only be issued for the sustainable amount actually covered in the bookkeeping, and not beyond it. For blends with fossil material, sustainability declarations may be issued only up to the bio-based share.
| Why Every Kilogram Must Be Genuine UCO
Why Every Kilogram Collected Must Be Certified-Eligible UCO
At Astra Sage, the page should say this very clearly: every kilogram accepted into the certified system must be genuine UCO from a verified Point of Origin. That is because the first certified supply-chain element for waste-derived material is the operator collecting the waste from the Point of Origin and becoming owner of it — the Collecting Point. ISCC defines the Point of Origin as the place where the waste or residue is generated, and for UCO that is typically the restaurant, canteen, kitchen, hotel, or food-processing site where the used oil arises.
Astra Sage’s Supplier Code requires suppliers to supply only genuine UCO, prohibits fresh or unused oil, expired-but-unused oil, and oils mixed with wastewater, sludge, or chemicals, and requires the supplier to name Astra Sage as the Collecting Point in the ISCC self-declaration.
The operational consequence is important: if water, sludge, sediment, heavy bottom layer, or other rejected non-conforming material is separated out during receiving, decanting, filtration, or later verification, it cannot simply disappear from the story. It must be recorded as rejection, quarantine, loss, or non-certified waste outside the accepted UCO balance. That is the only way to keep the ledger honest. This is an inference from Astra Sage’s own rejection, decanting, and fraud-control rules.
| Why Fraud Hurts Everyone
What Happens If Fresh Oil Is Disguised as UCO?
If fresh edible oil is falsely declared as UCO, the damage is not limited to one shipment. It distorts the whole market. Studies and policy reviews have warned that when UCO or UCO-based fuel is worth more than virgin oil, suppliers have an incentive to “turn virgin oil into UCO,” mix virgin oil into UCO, issue fake sustainability proof, or leave deliveries off the mass balance so the books still look correct on paper.
That matters because the fraud signal changes commercial behavior. If virgin edible oil can earn waste-based sustainability value, it creates pressure to divert food oils away from food markets and into fuel markets. CE Delft notes that high UCO values can incentivize virgin-oil fraud and even increased virgin-oil production, while more recent market concerns in the U.S. and Europe have focused on virgin palm oil being mislabeled as UCO to capture subsidies and sustainability value.
“If fresh edible oil is falsely counted as UCO, the result is market distortion. It rewards fraud, tightens food-oil supply, undermines climate policy, and can push food-system costs in the wrong direction.” That is strong, economically logical, and more defensible than predicting a literal market crash.
| How Astra Sage Controls the Chain
How Astra Sage Builds Traceability in Practice
Astra Sage’s process should be shown as a disciplined chain of control, not a simple pickup service. Your own documents already give the right backbone.
Supplier Onboarding
Astra Sage collects only from verified Points of Origin. During onboarding, the supplier must understand what qualifies as UCO and what does not, and Astra Sage checks plausibility against site type, fryer count, menu, hours, storage arrangements, and expected generation.
Supplier Education
The supplier is educated on eligible UCO, excluded materials, segregation, storage, contamination risks, and the consequences of false declaration. Astra Sage’s Supplier Code already makes clear that fresh oil, expired-but-unused oil, and contaminated material are prohibited, and that unexplained or unrealistic volumes are fraud indicators.
ISCC Self-Declaration
Before collection, the supplier signs a valid ISCC self-declaration for waste and residues and names Astra Sage as the Collecting Point. Astra Sage’s service agreement also requires a copy of that declaration to be kept at the premises and made available for audit.
Supplier Code of Conduct
The supplier signs Astra Sage’s Supplier Code of Conduct, committing to genuine UCO only, truthful Point-of-Origin declaration, honest reporting, audit cooperation, and stop-work acknowledgement.
Supplier Validation by Astra Sage
Astra Sage reserves the right to verify actual cooking operations, fryer count, fresh-oil purchase records, disposal records, and collection history to confirm that claimed UCO generation is genuine and plausible.
Collection Event Control
No collection should happen without a valid self-declaration on file, a signed UCO collection receipt, visual and sensory confirmation that the material is UCO, and a documented link to the verified Point of Origin. Any suspicion of non-UCO should abort collection immediately.
Batch Processing and Quantity Bookkeeping
At Astra Sage storage, all inbound material must be documented, traceable to the Point of Origin or approved supplier, assigned a Batch ID, and recorded into the mass balance ledger. High-risk mixing requires management approval, and mixing must not cause loss of traceability, averaging of GHG values, or negative sustainability balances.
Every Kilogram Is Accounted For
Accepted UCO is weighed, recorded, and booked. Non-conforming material, sludge, free water, sediment, or rejected bottom portion must be quarantined, rejected, or disposed outside the certified balance.
Sustainability Declarations Only When Covered
Astra Sage’s fraud procedure already states that Sustainability Declarations must reflect only what is physically dispatched and must be fully covered by mass balance.
| Point of Origin, Collecting Point, Buyer
Who Is Who in the Chain of Custody?
Point of Origin (PoO)
The Point of Origin is the place where the waste is generated. Under ISCC, that means the original waste producer. For UCO, this is typically the restaurant, hotel, food court, commissary, canteen, or food-processing operation where the used oil actually arises.
Collecting Point
The Collecting Point is the first certified operator that collects the waste from the Point of Origin and becomes owner of it. In Astra Sage’s model, Astra Sage is the Collecting Point. That role carries the responsibility for receiving valid self-declarations, documenting collections, maintaining quantity bookkeeping, and preserving mass balance integrity.
Buyer / Downstream Customer
The buyer is the certified downstream customer or processing partner who receives a documented consignment and, where applicable, a Sustainability Declaration backed by mass balance coverage. Under CORSIA and other sustainability systems, certified fuels and their claims must come through approved sustainability certification schemes and certified economic operators.
| How Astra Sage Controls the Chain
Waste-Based Climate Value Exists Only When the Waste Claim Is Real
UCO is valuable in renewable diesel, biodiesel, and SAF markets because it is a waste-derived feedstock. But that climate value is not automatic. It depends on proof of waste status, proof of origin, proof of chain of custody, and proof that the claimed sustainable quantity is actually covered in the mass balance books. ISCC requires that Sustainability Declarations only be issued for the sustainable amount properly covered, and EPA likewise requires renewable-fuel producers using used cooking oils to keep supplier records that certify the feedstock meets the renewable-biomass definition and describe how it was generated.
“When genuine UCO is fully traceable, it can support verified lifecycle emissions claims and, in applicable schemes, low-carbon credits or other sustainability-linked incentives. Without traceability, those claims should not exist.”
| Fraud Is Real
The Industry’s Fraud Problem Should Be Faced Openly
The market has real fraud risk, and serious operators must say so openly. ISCC itself treats intentional contamination or modification of material to count as waste as fraudulent activity and a critical non-conformity.
Malaysia
Malaysia’s deputy commodities minister told Reuters in 2025 that the country would crack down on fraud in UCO exports because Western governments were investigating whether shipments from Asia actually contained virgin oil. He said MPOB was reviewing standards to better distinguish UCO from sludge palm oil and stressed that full supply-chain traceability is the center of the issue.
China
Fraud concerns around China have been serious enough that U.S. lawmakers in 2024 sought a crackdown on surging Chinese UCO imports, citing fears that some cargoes could actually include virgin palm oil. In 2025, the European Commission concluded its examination of Chinese biodiesel fraud allegations by identifying systemic weaknesses in certification audits, even though it said the information gathered did not allow confirmation of fraud in that specific case.
Indonesia
Indonesia has also been part of the fraud conversation. Reuters reported in 2025 that neighboring Indonesia had moved to curb exports of UCO and palm-oil residues after shipment volumes appeared to exceed production capacity, indicating possible mixing with virgin crude palm oil. The EU had earlier launched an investigation into whether biodiesel from Indonesia was circumventing duties by transiting through China and Britain.
The message for Astra Sage is simple: traceability is not bureaucracy. It is market defense.
Traceability Is the Product
Astra Sage is not building a loose collection network. We are building a defensible chain of custody for genuine waste-derived UCO — from Point of Origin to Collecting Point to buyer. That is how sustainability stays credible, how fraud is stopped, and how long-term trust is earned.
