Production of electricity from pig farm wastes

This is the good practice's implementation level. It can be national, regional or local.
About this good practice
The biogas unit manages approximately 200 tn per day of animal waste from the pig farm as well as approximately 150 tn per day organic material from local producers (poultry farms, cheese and dairy producers, olive oil producers, cultivations etc). The Installation is fully integrated (vertical production) and includes a slaughterhouse, a Dissolved Air Floatation system (DAF) for the treatment of waste water and a biogas production unit for the anaerobic digestion of animal solid waste and other organic material. Small farmers often lack the capacity to manage the waste produced on their farms. In order to address this problem and create added value, the company farm, an industrial scale pig farm which also operates a biogas plant, came up with the idea of working with local farmers. Farmers sign a contract with the company, which in turn collects the waste from their farm and transfers it to its biogas plant to produce biomethane. The biomethane production unit uses waste produced by poultry farms, dairy farms, local fish farms, etc. Apart from the biomethane production, the digested material from this process is turned into a fertilizer for local farmers. The farm keeps daily records of all biomethane production parameters, including all of its inputs and outputs.
Resources needed
6.000.000 Euros (€)
Evidence of success
The farm efficiently processes waste from local farms, that in the past would be disposed of in an uncontrolled manner into the environment.
Digested material is now turned into energy, as well as high-quality fertilizer for local use. The fertilizer could also be sold to other farmers at National Level.
50 individuals directly employed in/by the initiative and 100 indirectly employed (e.g. in spin-offs of the initiative, suppliers, transport, etc.)

Potential for learning or transfer
Agriculture and livestock farming organic residues can be used to meet energy needs (heating, cooling, electricity generation, etc.) either by direct burning or by conversion to gaseous, liquid and/ or solid fuels. Depending on the available biomass source, the corresponding process for optimal energy utilization is selected.
The connection of local farmers and producers in remote areas and villages is an important lesson, since they can self-organize into farm-associations and create their own biogas production units. The environmental impact of poultry and pigs waste in the area would be very problematic if this plant did not exist
