In the recent years, the number of biogas plants in Slovenia has remained unchanged. However, elsewhere in Europe, the number of biogas plants is increasing, and so is the production of biogas and biomethane, together with the likelihood of the occurrence of various accidents such as digestate spills, gas explosions and the like. Due to the high concentrations of nitrogen and phosphorus, an uncontrolled digestate spill poses a risk to the environment and to groundwater. Poor maintenance of technical equipment, technical errors in measuring devices, and inadequate training of biogas plant operators increase the likelihood of the occurrence of accidents.
