We Supply Facilities for Production of Sustainable Fertilizer and Substrate

CO2 neutral

The most sustainable produced substrates on the market – CO2 neutral

Sustainable – organic

Sustainable produced liquid fertilizer for organic plant production

To less than 3,6%

Reduce the dry matter content of the digestate to less than 3,6% as required in the Danish legislation
