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 €


Monitoring an evaluation of treatment technologies and management schemes at research centre Foulum (Denmark).

Aarhus University will evaluate and monitor a full-scale anaerobic digestion plant, fed with raw pig slurry, and a prototype of an anaerobic filter reactor.

a) Full-scale anaerobic digestion treatment plant:
The steps to follow are:

  1. separation (flocculation)
  2. stripping of ammonia
  3. anaerobic digestion (AD)
Manure treatment process: Phases separation + Stripping to produce a concentrated nitrogen fertilizer

b) Prototype of an anaerobic filter reactor (AF reactor): The objective is to obtain a small size reactor while maintaining a high methane production. To achieve this it is required an inert material introduced into the reactor where microorganisms grow as a bio-film.
