Besides encymes the mechanical decomposition of substrates is most widespread. We as biogas plant operators use mechanical decomposition of substrates as long as we operate plants

Many "new" procedures to increase the biogas yield from the substrates are developed and propagated particularly in economically difficult times. The best known techniques at the market are

Micronutrients or trace elements (these are mostly heavy metals) are needed in all biogas plants. The micronutrients are the central atoms in the enzymes which must be produced by the methane bacteria in order to produce biogas. Without micronutrients there is also no biogas.

At the operation of biogas plants acidification of the digester is one of the most expensive problems. When the digester biology is acidotic, it can possibly last months,

The introduction of „Technical Rules for Hazardous Substances 529 (TRGS 529)“ in Germany earlier this year lead to several new provisions for operators of biogas plants.

In the biogas branch a new business segment developed in the previous years: the biological support of plants and the analysis of digester contents for essential trace elements or micronutrients. As these analysis are quite expensive, it is worth to question their sense.

Meanwhile, the use of micronutrients or trace elements in biogas plants is a generally acknowledged rule of technology. Till 2007 this was not the case at all. Till 2007 micronutrients were only used in the lab for scientific purposes or sometimes with the fermentation of industrial wastewater.

When I started constructing and commissioning the first high-loaded biogas digesters (digester load 8-10 kg oDM/cbm/d) in 2005,

The still common understanding assumes the existence of a mesophilic (35 - 40 °C) as well as a thermophilic (50 - 55 °C) temperature range for the biogas production.
