Evaluation of manure management and treatment technology for environmental protection and sustainable livestock farming in Europe.

MANEV is an European project of large-scale demonstration framed within the LIFE + Programme of Environment Policy and Governance, whose main objective is to improve environmental protection and sustainability of livestock promoting the use of treatment technologies in different saturated or surplus areas in the production of livestock manure across Europe.

8 partners will assess 13 treatment technologies and manure management systems, located in 8 regions with high pig production belonging to 4 European countries, following a common monitoring and assessment protocol that will be developed a long the project. The results of each assessment could be referred to CO2 equivalent units in order to assess its contribution to fight against climate change.

A software tool will be developed based on the results and all the information and data obtained from the technology assessments developed in the project, which is intended to provide an objective decision support tool to determine the most appropriate treatment according to the local circumstances, without being these mere technological comparison but taking into account aspects like for example environment, society, economics, local regulation,… of every study case. Europe will be endowed with a common decision support tool to the various technologies beneficial for both farming sector (search for the optimal technology) and the administration (environmental control and promotion of the use of technologies).

DURATION: 48 months (January 2011 – December 2014)


  • Total budget: 4.165.832 €
  • European co-financing: 2.076.153 €

Action: CEBAS-CSIC Scenario

Monitoring and evaluation of manure management strategies in the region of Murcia (Spain).

CEBAS-CSIC will monitor and evaluate the COMPOSTING of the slurry in Murcia according to the common monitoring protocol. The following tasks will be developed:

  1. Evaluation of the distribution of pig slurry in the Region of Murcia and identification of the key points where slurry is produced in excess in relation to the available agricultural land.
  2. Identification of appropriate agricultural soils for pig slurry application according to the crop and nutrient balances.
  3. Establishment of the technical requirements for transformation of pig slurry by COMPOSTING. Determination of the feasibility of composting as an alternative for recycling pig manure in the Region of Murcia.
  4. Feasibility of the combination of anaerobic digestion and composting of the digestate for manure management: The composting technology will be studied for transformation of the digestate generated in biogas plants based on pig slurry anaerobic digestion.
  5. Identification of the benefits and constraints in manure and slurry composting: economic, environmental and agricultural.
  6. Environmental and quality indicators of composting technology: Compost environmental and quality indicators will be reviewed, highlighting the most relevant factors applicable to pig slurry.
  7. Implication of composting on the carbon cycle: C-conservation and sequestration: A balance between the CO2-emissions from composting and after soil use, in comparison with the direct soil application of raw manure, is required for determining the C-conservation and the best option for C-sequestration.
