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.
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.
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.
Soybean Acid Oil
Soybean acid oil is the acidulated soapstock from soybean refining. It is the cheapest route to a soybean-derived ester, but its high polyunsaturate content gives the resulting fuel poor oxidation stability.
Rapeseed Acid Oil
Rapeseed acid oil is recovered by acidulating the soapstock from rapeseed oil refining. As a residue stream it qualifies as waste-based feedstock, and its high free fatty acid content routes it to acid esterification rather than the alkali process.
Sunflower Acid Oil
Sunflower acid oil is the acidulated soapstock from sunflower oil refining. It is generally paler and lower in phosphatides than soybean or rapeseed acid oil, which makes it marginally cleaner to process.
