LIFE + MANEV PROJECT

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)

BUDGET OF THE PROJECT:

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

Action: CRPA Scenario

Monitoring and evaluation of processes based on utilization of energy from biogas to manage nitrogen content and GHG emission from pig slurries in Emilia-Romagna region (Italy).

CRPA will assess in Emilia-Romagna region two typologies of systems:

  1. a) Systems for the removal of the nitrogen contained in the slurries based on reducing the power of pollution (SHARON process and MBR).

    b) Conservative systems of nitrogen and the phosphorus contained in the slurries for their agronomic use (stripping).

    These systems are integrated into two treatment plants as desdribed below:

    1. Anaerobic digestion + Sharon process (at farm level). Monitoring and assessment of a treatment plant located in Basilicagoiano (Parma). A biogas plant will provide energy for the treatment of the clarified fraction of the slurry in an innovative process of nitritation-denitritation, called Sharon (using a SBR, designed in collaboration with the firm SIBA, ex SAGIDEP). The plant consists of a prototype with a volume of 2,4 m3 and a treatment capacity of 0,35 to 1 m3/day slurry after anaerobic digestion.

    2. Anaerobic digestion + solid/liquid separation + stripping + nitrification-denitrification. Monitoring and assessment of a treatment plant, developed by the company IDROENGINEERING, in a farming business. The San Salvatore pig farm is a closed cycle, about 800 sows + fattening for a total of about 650 tonnes of live weight; the daily production of slurry is about 100-120 m3. It is located in Sospiro (Cremona).

    The process line is made up with the following process units:

    1. An anaerobic digestion of thickened fraction from flotation of pig slurry in a mixture with agroindustry byproducts. The biogas is used in a co-generator of 250 kW of electrical power.
    2. A solid/liquid separation of digestate with a centrifuge.
    3. An ammonia stripping of the clarified fraction from flotation and centrifuge.
    4. An aerobic treatment with denitrification-nitrification of the effluent from ammonia stripping unit with a Membrane Biorector (MBR).
