Micronutrients

Minimum dose — maximum effect 

As early as 1989, Dr. Friedmann experimented with micronutrients during research work on the fermentation of wastewater from baker's yeast production. After it became clear that the micronutrients had to be "visible" to the methane bacteria, considerable success was achieved. 

It was only recognized in 2006 and 2007 that the use of micronutrients also brings significant efficiency advantages in agricultural biogas plants. So-called dry fermentation plants initially only used silage as a substrate. This caused biological problems that were quickly remedied with suitable micronutrients. 

Micronutrients are now established in all modern biogas plants. Even with pure liquid manure fermentation, the addition of micronutrients brings efficiency advantages. In order to minimize effort and costs, a formulation with optimal bioavailability of the micronutrients is essential.
