Our Renewables

Animal fat

Animal Fat CAT.1

Animal Fats CAT. 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

CAT.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 fatties 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 Methyl Esters are waste and residue from palm oil production. When collected and processed into a renewable feedstock, POME is an exclusive biofuel.

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 SA.
