Results

The project pursues the following expected results:

Economic viability of the project:

  • 50% cost saving of liquid fertilisers vs inorganic fertiliser
  • 70% substitution of inorganic fertilisers in the project area

Positive environmental impact:

  • Prevention of CO2 emissions vs inorganically fertilised fields (estimation of 3.600t CO2 saved).
  • 20% increase in nutrient absorption capacity of the plant vs inorganic fertilised fields, leading to reduction of nitrogen and phosphorous in the ecosystem.
  • 30% reduction of phosphorus present in tested pig manure vs manure of conventionally bred pigs. The project intends to reduce approx. 3.400 kg of P in tested pig manure.
  • Savings in energy and chemical use through biological treatment of ammonia in the gas stream when drying solid fraction with recirculated liquid fraction of digestate.
  • Positive effects on the organic load in wastewater from pig manure: by preserving the presence of N and P in the liquid fraction of the digestate, we will save on energy and costs on the otherwise required treatment of wastewater. This current practice leads to environmental problems and goes against the principles of the circular economy.

Report the impact of the project on the environmental problems identified and the socioeconomic benefits for the target audience.

Create list of appropriate doses of the liquid fertiliser required per crop type tested in the project, as well as step-by-step manual to implement the integrated approach for third parties.

Demonstrate high replicability potential by actively engaging stakeholders, especially other biogas plant operators.
