Biofertiliser for agriculture

Biofertiliser – Plant nutrients put to good use again
Biofertiliser is a byproduct when producing biogas. It contains plant nutrients such as nitrogen, phosphorus, and potassium and can be used as fertiliser in agriculture.
St1 Biokraft produces biofertiliser that can replace or supplement mineral fertiliser.

From biogas production back to the field
By using the digestate remaining after biogas production as fertiliser, plant nutrients from organic waste can be returned to agriculture.
The properties of the biofertiliser depend, among other things, on the substrates used and how the digestate is processed.

Quality and control
We conduct quality assurance and testing of the biofertiliser's composition, and we offer several biofertiliser products that are certified according to SPCR-120. The certification ensures that decomposed materials are clean, source-separated, and biologically easy to break down. We produce biogas from waste that cannot be used as food or animal feed.
