Trace elements
Why Trace Elements Are So Important.

The key to stable biological processes and high methane yields.
Without the right trace elements, no biogas plant can operate reliably. Iron, nickel, cobalt, and selenium regulate key enzymatic processes involved in methane production. Even small deficiencies slow down the microorganisms—gas yield decreases, the biological system becomes unstable, and the digester reacts sensitively to stress.

The Challenge—Every System Is Unique
A biogas plant is as unique as a fingerprint. Substrates, effluent, pH levels, and trace element availability vary greatly. Standardized bagged materials or one-size-fits-all formulations therefore often lead to:
- Under- or over-dosing
- Precipitation caused by sulfur
- imprecise results
- unstable processes
Trace Elements in Biogas Plants
What role do trace elements play in a biogas plant?
Trace elements support the microorganisms in the digester. They are important for enzymatic processes, substrate degradation, process stability, and methane production.
Which trace elements are particularly important for biogas plants?
Important trace elements include, among others, nickel, cobalt, selenium, and iron. They are involved in key biological processes of methane formation.
Can custom trace element blends be produced?
Yes, custom mixtures can be produced for all SaMpower trace elements. Based on laboratory analyses, substrates, and the requirements of the respective biogas plant, the trace element supply can be specifically tailored to the actual needs of the digester.
How can you recognize a trace element deficiency?
A possible trace element deficiency can manifest as declining gas production, lower methane content, rising levels of fermentation acids, foaming, unstable pH values, or a decline in substrate utilization.
Why should trace element supply be based on analysis?
Every biogas plant has different substrates, process conditions, and biological requirements. A laboratory analysis helps tailor the supply specifically to the actual needs of the plant.
Why is bioavailability important for trace elements?
Trace elements must not only be present in the digester but also be able to be utilized by the microorganisms. If they are bound or precipitated, they are only available to the biology to a limited extent.
When should the trace element supply be checked?
A review is advisable in cases of declining gas production, unstable biological activity, substrate changes, abnormal laboratory results, or if the plant is not reaching its performance potential.
