NEW PROJECT: Best Available Technologies for Pig Manure Biogas Plants in the Baltic Sea Region PDF Print E-mail

Baltic Sea 2020 intensifies the effort to reduce leakage of nutrients from industrial pig farms in the Baltic Sea Region. A new project was initiated in June, with the objective to improve the environmental and economic performance of anaerobic (biogas) treatment of slurry from the pig production. Relevant current technologies will be analyzed regarding their cost efficiency to minimize leakage of nutrients to surrounding waters. The Danish “Centre for Bioenergy and Environmental Technology” runs the project, in partnership with Finnish “MTT Agrifood Research”  “and “Swedish Institute of Agricultural and Environmental Engineering”. The analysis is performed during this autumn, and results will be communicated to concerned industry and responsible authorities during next spring.

Background
The Baltic Sea 2020 Intensive Pig Production Programme aims at promoting the best available techniques for pig manure management to reduce the leaching to the Baltic Sea. The recent overview of best available techniques for manure treatment has recommended anaerobic digestion (biogas) as the best well proven technique to reduce N-leaching from pig production (Foged, 2010).  As additional biomass substrate is becoming scarce, there is a strong need to optimize the biogas plant function as well as analyzing existing techniques to find the best and most cost effective method.

 

 

Objectives
  • Compare different technologies for anaerobic digestion and evaluate the methods based on efficiency and cost.
  • Analyse cost-benefit of the different biogas plant types under different national framework conditions.
  • Identify suitable handling techniques for the digestate from digester to fields for plant uptake.
  • Analyse the optimal use of the biogas for energy purposes, such as fuel, upgraded for gasgrid or for Combined Heat and Power plants (CHP) power production.
  • Recommend a current ‘standard’ of combined validated techniques proven for best performance for treating pig manure under different national framework conditions.
  • Recommend the economically and environmentally optimal solutions for local use of produced biogas and nutrients in the degasified slurry, depending on the national conditions and ecological region.

Deliverables
  • Report on specific technologies that have proven durability and efficiency for treatment of pig slurry in the Baltic Sea region.
  • Recommendations for ‘standard models’ and optimal combinations with other pre- and post-treatment technological solutions of small, medium and large scale biogas plant for pig manure.
  • Economic performance of different types of biogas plants under different national conditions (economically and environmentally).
  • Presentation of the achieved results at relevant seminars in Baltic Compass, BATMAN and Baltic DEAL projects and other relevant fora.
  • Articles of the recommendations in selected relevant national media.
