More about our renewables
Nothing is wasted

Our Renewables

Animal fat

Animal Fat CAT.1

Animal Fats CAT. 1 is veterinarian material unsafe for any kind of consumption, great for biofuel. When purified these (CAT.1) fats are good for the production of 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 material suitable for technical or chemical use as fertilizer and greaser. Purified it becomes clean and suitable for the production of green biofuel.

Animal Fat CAT.3

As a byproduct of veterinarian waste streams CAT.3 fats can be rendered and processed further into feed, or technical and oleochemical grade fats and products. In our hands it becomes high quality feedstock for biofuel.

Fatty Acids

Depending on its origins Fatty Acids can be the product of the physical refining by distillation of 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, but it is not wasted.


Palm Oil Methyl Esters are waste and residue from the production of palm oil. Collected and processed into a renewable feedstock, this POME is a biofuel exclusive.

Sewage sludge

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

Soapstock Acid Oil

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


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