Advanced Feedstocks

Emerging and advanced renewable materials supporting the next phase of sustainable fuel development.

Our Products

Animal fat

Animal Fat CAT.1

Animal Fats Category 1 is a veterinarian material that is unsafe for any kind of consumption but great for biofuel. When purified, these (CAT.1) fats are suitable for producing green FAME.

Animal Fat CAT.1 refined

The same raw material of animal origin, too high in metals and impurities to use instantly, but when purified and rightfully refined, it can be the perfect green particle of the (close to) green HVO.

Animal Fat CAT.2

Category 2 animal fats are intermediate-risk materials suitable for technical or chemical use as fertilizer and greaser. Purified, they become clean and suitable for the production of green biofuel.

Animal Fat CAT.3

Category 3 fats can be rendered and processed further into feed or technical and oleochemical-grade fats and products as a byproduct of veterinarian waste streams. In our hands, they become a high-quality feedstock for biofuel.

Fatty Acids

Depending on their origins, Fatty Acids can be the product of physical refining by distilling veterinarian residues or vegetable oils. Different sources, yet both Fatty Acids.

Food Waste Fat

These fats are extracted from food and consumption residues. Fats extracted from leftovers need a few extra transformational steps to be used as a green-valued feedstock.

POME

Palm Oil Mill Effluent (POME) is a by-product of palm oil processing: water, oils, and organic solids that, once refined, serve as renewable feedstock for advanced biofuel production.

Sewage sludge

Sewage sludge is a typical advanced feedstock. Fats, often wastewater from kitchens, are quite easily extracted in wastewater treatment, but this takes a lot of handling.

Soapstock Acid Oil

A residue from the neutralization of crude vegetable oil, like rapeseed, soybean, or sunflower. The separation leaves a weakly acidic solution of phospholipids, water-soluble fats, oil, and acid residues.

UCO

Used Cooking Oil (UCO) is an enormous global waste stream from restaurants, fast-food brands and food processing companies. Purified and processed UCO can be converted into high-quality renewable fuels such as FAME, HVO and SAF.

Waste streams with a second purpose

Renewable feedstocks created from waste and residue streams help reduce emissions while supporting renewable fuel production at industrial scale. Waste and residue streams once treated as end products can now play a structural role in replacing fossil-based fuels. From Used Cooking Oil and Animal Fats to Advanced Feedstocks, these renewable streams play an increasingly important role in creating lower emission energy systems and reducing dependence on fossil based fuels.
