Biogas Plant in Batka,
FIGA is a large-scale farm in Batka, district of Rimavska
Sobota, with pigs and 220,000 egg-laying hens. In response to an initial
problem of animal manure disposal, a biogas plant was built in 1992-95. The
owner of the farm paid half of the costs of the project and the Slovakian
ministry of agriculture covered the other half. The payback time is estimated
to be 6 years. The technology used is a mix of Austrian know-how (Bauer) and
Since its installation, the biomass
plant has received 166 t. of animal manure a day from the farm and provides
the farm with:
24.9 GJ/day (winter min.)
41.2 GJ/day (summer max.)
GJ/day (annual average)
The remaining product - the digested sludge - is a high-value
fertiliser used on the fields.
The benefits of the biogas plant
- own, stable, self-sufficient energy production (electricity and heat)
- cheap energy, which yields financial savings in the longer term.
- possibility of selling energy surplus - a source of extra income for the
- reduction of obnoxious smells from the manure
- solution of the manure-disposal problems
- production of high-volume fertiliser that carries a higher content of
nitrogen (15% more) than artificial fertilisers, and that does not burn the
crops, as un treated slurry can do. This reduces the need for expensive
- better control of the waste from many animals means less pollution of
local environment and water sources.
- a veterinarian aspect: In the bioplants, viruses are killed. The risk of
spreading animal infections in the area is thereby reduced.
- removal of chemical fertilisers from the fields and recirculation of
nutrients results in healthier vegetables and fruits for human consumption.
- local power plants contribute to creating permanent local jobs in the
On a national basis, widespread use of the biogas plants
could deliver a badly needed means of energy self-sufficiency, and the
decentralised structure of the biogas plants means less need for expensive
distribution of energy in rural areas. On a global basis, it reduces the use
of fossil fuels and, thereby, emissions of CO2. At the same time,
biogas plants control, and therefore reduce, the emission of methane, a
greenhouse gas that is 20 times more aggressive than CO2.
