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 €


Assessment of a collective treatment and management scheme for energy production and nitrogen removal in Lombardy (Italy).

University of Milan will assess a collective treatment plant with anaerobic digestion (AD) and nitrogen removal.

The treatment plant will collect the manure produced by 10 individual farms (pig, cows and poultry) with a total production of 300 m3/day.

The manure collected from the different farms is transported by pipeline or by slurry tankers to the plant where it is treated in a first stage of anaerobic digestion (AD) in order to recover biogas. Next a phases separation will produce a liquid and a solid fraction.

Liquid fraction is treated in a Sequentially Batch Reactor (SBR) for nitrogen removal through a process of nitrification and denitrification (N/DN). A solid-liquid separation stage is inserted between the AD and the SBR to reduce the load and to separate most of the phosphorus. The solid fraction can be managed in order to avoid P surplus in the area.

Scheme of the AD+SBR treatment technology.


  • Anaerobic digesters.

  • Input of biomass to the process.

  • Solid fraction.

  • Aeration process in the SBR reactor.
