Skyler connects used cooking oil (UCO) suppliers with sustainable aviation fuel (SAF) producers — building the certified supply chain aviation needs to decarbonize.
Skyler's platform connects every step of the UCO-to-SAF supply chain with real-time data, ISCC certification, and an immutable audit trail.
Skyler coordinates regular collection from restaurants, caterers, and food manufacturers. Each pickup is logged with GPS timestamp, volume, and quality grade — creating the first link in the chain of custody.
Every batch is certified under the International Sustainability & Carbon Certification (ISCC) standard. Certificates are generated automatically and attached to each lot — no manual paperwork, no gaps in the audit trail.
Every transfer, test result, and certification event is recorded on an immutable ledger. SAF producers and airlines can verify the full provenance of every litre — from the restaurant kitchen to the refinery gate.
SAF producers receive certified UCO batches matched to their volume requirements and blending mandates. Carbon credits are calculated and issued automatically at point of delivery.

Most UCO aggregators stop at collection. Skyler owns the full data layer — from pickup to proof.
We don't just move oil — we capture every data point along the way, giving buyers the documentation they need for regulatory compliance.
ISCC certificates are generated programmatically per batch, eliminating manual errors and weeks of back-and-forth with auditors.
Carbon intensity is calculated at batch level using verified emission factors, so credits are accurate and audit-ready from day one.
One-click exports for ReFuelEU Aviation, CORSIA, and national blending mandate reporting — no spreadsheet wrangling required.
Airlines need low-carbon fuel that works in today's engines, at scale, under rules that keep getting tighter. Used cooking oil is one of the few feedstocks that already meets all three.
UCO is a residue of cooking. Collecting it adds no land to cultivation and takes nothing away from food supply.
Used cooking oil is listed in Annex IX Part B of the EU Renewable Energy Directive, so fuel made from it counts toward ReFuelEU Aviation when it meets the directive's sustainability and greenhouse-gas criteria.
Through the HEFA process, refiners turn UCO into jet fuel (SAF) and renewable diesel (HVO) that blend into existing fuel systems.

Vietnam's restaurants, street-food kitchens and food manufacturers produce a large and widely scattered stream of used cooking oil. Public data on it is scarce, which is exactly why buyers need a supplier that documents every batch from the first pickup.
Rough estimate of used cooking oil generated in Vietnam. Unofficial figure; documented data is limited.
Raw UCO arrives with water, food solids and variable acidity. Before export, every batch is filtered, settled and dewatered to bring it within the buyer's specification, then tested and documented.
Target 2028: our own pre-treatment module running in Vietnam.
Whether you generate waste oil or need certified feedstock, Skyler delivers real value.
Eliminate disposal costs, gain sustainability credentials, and contribute to aviation's net-zero future — all with zero operational overhead.

Skyler is an early-stage company building a traceable supply of used cooking oil from Vietnam for the world's SAF and renewable diesel producers. We collect, pre-treat, document and certify, so the oil that leaves a kitchen can be proven all the way to the refinery gate.
We are preparing our first export shipment for 2027 and working toward ISCC EU certification in the same year.
Vegetable oils and animal fats that have already been used for frying or cooking in kitchens and food production. Each batch is tested; oil mixed with mineral oil, chemicals or other waste can't be accepted.
No. Scheduled pickup is free, and suppliers receive a sustainability certificate for the oil they hand over.
We are starting in Vietnam, collecting from food-service and food-manufacturing sites and exporting pre-treated UCO to SAF and HVO producers.
Our first export shipment is planned for 2027, and ISCC EU certification is targeted for the same year. Talk to us now to plan volumes for those years.
Yes. The same pre-treated UCO is a feedstock for both SAF and HVO, and we work with producers of either.
Every pickup is logged with location, time, volume and quality grade and given a batch ID. That record follows the batch through pre-treatment, testing and certification to delivery.
