Researcher's progress: Here the sandwich is made with butter made from carbon dioxide and electricity

Hear the chemist Anders Lorén explain how the fat products are made in the clip above.

Carbon dioxide, water and energy.

In theory, this is all that is needed to be able to do something that can be eaten.

But often large amounts of land are exploited in connection with this or it contributes to carbon dioxide emissions.

Neutral food fat

Something you, according to researchers, should be able to partially avoid if you take the carbon monoxide directly from the air to create food.

Now they have succeeded in producing a neutral cooking fat, both spreadable and in liquid form, which is created entirely from carbon dioxide from the air, electricity and water.

- The sustainability gains are huge, above all we win in land use and emissions of nitrogen and phosphorus.

What you need to do is that you need to expand and get more power, says operations manager Anders Lorén.
