Waste-Based Feedstock
Used Cooking Oil, POME and Acid Oils.
Sugarcane juice, molasses, maize, rice, and other starch crops serve as sustainable feedstocks for ethanol production. These agricultural resources power the transition to cleaner biofuels, reducing dependence on fossil energy and supporting a circular, low‑carbon economy.
Crude vegetable oils, used cooking oil, and refining by‑products such as PFAD, acid oil, and sludge oils serve as essential feedstocks for Fatty Acid Methyl Esters (FAME) biodiesel. These renewable and cost‑effective sources drive sustainable fuel manufacturing and circular energy recovery.
Feedstock Families

Documentation & Compliance
ISCC chain-of-custody, sustainability declarations, specification sheets, third-party inspection reports.
Biofuel Feedstock Sourcing Built on Your Plant's Limits
Biodiesel, HVO and SAF feedstock has to satisfy three desks at once: procurement wants volume, the plant wants its pretreatment limits met and compliance wants mass-balance evidence. At Bio Green Fuels, we check UCO, POME, acid oils, PFAD and PKFAD against all three before an offer is made.
Used Cooking Oil (UCO), PFAD or Acid Oil for Your Route
A biodiesel line needs low FFA and water after pretreatment; an HVO or SAF unit tolerates high FFA but needs phosphorus, metals, chlorine and polyethylene removed. We read each UCO, acid oil or distillate analysis against the limits your route runs to.
Lot Analysis and Sustainability Evidence
Depending on source, each offer can include a lot-specific COA with test methods, SDS and specification, plus sustainability and traceability evidence with mass-balance chain of custody where applicable. RED III Annex IX classification remains your certification body's decision.
Feed Slates Planned for Biodiesel, HVO and SAF Plants
We help procurement teams build a feed slate across UCO, acid oils, fatty acid distillates, CNSL and crude vegetable oils, comparing loading port, parcel size, monthly or spot volume and delivery window, so your plant is not tied to a single stream.
Trial Parcels, Then Vessel or ISO Tank
Where available, samples and trial parcels let your laboratory and plant prove a stream before term supply, with a referee lab agreed up front. Shipments move by bulk vessel, ISO tank or flexitank, with heated discharge for palm-rich lots.
From UCO or PFAD Spec to Discharge Port
Your FFA, MIU and phosphorus limits follow each UCO, acid oil or PFAD lot through pretreatment screening, COA and traceability review, referee testing and loading.

UCO, POME and PFAD Parcel Test Data and Sourcing Trail
Plant labs read the COA against pretreatment limits; sustainability teams read origin evidence, which differs for collected UCO, POME, acid oils and PFAD. Gaps are flagged before you contract.

Feedstock Matched to Your Fuel Route
Biofuel feedstock for biodiesel, HVO and SAF producers, oleochemical plants and rendering operations worldwide.
Biodiesel Producers
Biodiesel, or fatty acid methyl ester (FAME), is made by transesterifying oils and fats with methanol, usually over an alkaline catalyst…
HVO Producers
Hydrotreated vegetable oil (HVO), also sold as renewable diesel, is made by hydrodeoxygenating oils and fats over a catalyst and then…
SAF Producers
Most sustainable aviation fuel (SAF) produced today comes from the HEFA route (hydroprocessed esters and fatty acids).
Renewable Chemicals & Oleochemicals
Renewable raw materials are not only fuel feedstocks.
Feedstock Pre-treatment & Refining
Pretreatment sits between the collection of a waste or residue and its conversion into biodiesel, HVO or SAF.
Industrial Ethanol & Blend Components
Ethanol is used both as a renewable fuel component, most visibly in E5 and E10 petrol, and as an industrial solvent and chemical…
Featured Feedstock
Refinery-grade feedstock qualified against your specification
Methanol
Methanol (CAS 67-56-1) at 99% minimum, the alcohol that converts vegetable oils, used cooking oil and acid oils into methyl esters. Charged in excess for transesterification and recovered for reuse, it also carries the methoxide catalyst.
Biodiesel transesterificationSodium and potassium methoxide preparation
Used Cooking Oil (UCO)
Used cooking oil is the highest-value waste feedstock in the biofuel market, qualifying under RED II Annex IX for double counting. Frying degrades it, so free fatty acid, polymer content and moisture are confirmed per source.
Biodiesel (FAME) after esterification pretreatmentHVO / renewable diesel feedstock
Soapstock Acid Oil
Soapstock acid oil is the generic acidulated refinery residue, made from whatever oils a refinery was processing. It is the cheapest fatty feedstock available and the most variable, so it is always bought against a lot analysis.
Biodiesel after acid esterification or glycerolysisHVO feed after pretreatment
Distillers Corn Oil
Distillers corn oil is recovered from the stillage of dry-mill ethanol plants, after the starch has already been fermented. Because it is a residue rather than a crop, it qualifies as a waste-based feedstock under most incentive schemes.
Biodiesel after esterification pretreatmentHVO / renewable diesel feedstock
Palm Methyl Ester
Palm methyl ester is finished biodiesel, produced by transesterifying palm oil with methanol. It offers one of the highest cetane numbers and best oxidation stabilities of any FAME, with cold-flow behaviour as its limiting property.
Biodiesel blendstockRenewable diesel component
Palm Fatty Acid Distillate (PFAD)
Palm Fatty Acid Distillate (PFAD), rich in free fatty acids, is an abundant and low‑cost feedstock converted via esterification and transesterification into biodiesel (FAMEs) or hydrotreated renewable diesel (HVO), making it a critical waste‑derived resource for sustainable energy production.
Biodiesel by direct esterificationHVO / renewable diesel feedstock
Palm Kernel Fatty Acid Distillate (PKFAD)
PKFAD is the deodoriser distillate from palm kernel oil refining, rich in lauric and myristic acids. As a processing residue at high free fatty acid content, it is a low-cost esterification feedstock for biodiesel and renewable diesel.
Biodiesel by direct esterificationHVO feed as part of a blended slate
Crude Soybean Oil
Crude soybean oil is the dominant biodiesel feedstock in the Americas. Its high linoleic content gives good cold-flow properties but the weakest oxidation stability of the major feedstocks, so antioxidant treatment is standard.
Biodiesel (FAME) after degumming and dryingHVO feed after pretreatment
Crude Rapeseed Oil
Crude rapeseed oil is the reference biodiesel feedstock in Europe. Its high oleic and low saturated content give rapeseed methyl ester the best cold-flow behaviour of any major FAME, which is why it dominates in temperate markets.
Biodiesel (RME) after degumming and dryingWinter-grade FAME production
