Biogas – renewable fuel able to substitute fossil fuels
For a wide range of organic substances from agriculture,
foodstuff or feed industries, anaerobic fermentation is a
superior alternative to composting.
Biogas …
• results from anaerobic fermentation of organic materials
• is a mixture of methane and carbon dioxide
• serves as a high-energy, CO2-neutral fuel

For the Farmer:
improvement of manure properties: odor reduction, elimination of acid
components, viscosity decrease, mineralization of organic nitrogen,
reduction of pathogenic germs and weed seeds
additional incomings from heat and power production
waste water treatment without costly sewer connection
For the Environment:
reduction of methane and ammonia emissions from manure
reduction of nitrate wash-out into groundwater
recycling of fertilizer compounds from organic wastes
reduction of carbon dioxide emissions by substitution
of fossil resources

Biogas potential EU
•
The existing biomass resources on our planet can give us an idea of the global
potential of biogas production.
This potential was estimated by different experts and scientists
Regardless the results of these estimations, the overall conclusion was always, that
only a very small part of this potential is utilised today, thus there is a real possibility
to increase the actual production of biogas significantly.
The European Biomass Association (AEBIOM) estimates that the European
production of biomass based energy can be increased from the 72 million tones
(Mtoe) in 2004 to 220 Mtoe in 2020.
The largest potential lies in biomass originating from agriculture, where biogas is an
important player. According to AEBIOM, up to 20 to 40 million hectares (Mha) of land
can be used for energy production in the European Union alone

Bioplinski potencial v Sloveniji
•
V Sloveniji je 16 bioplinarn, v Nemčiji pa že več kot 6.000
s skupno močjo več kot 2.000 megavatov.
•
V Sloveniji je po analizi kmetijskega inštituta dovolj potenciala, da bi zgolj z biomaso,
pridelano na 3 odstotkih obdelovalnih površin (670 tisoč hektarjev), lahko postavili
več kot 86 megavatov bioplinskih elektrarn. Pri tem proizvodnja hrane ne bi bila
ogrožena, kmetje pa bi imeli zagotovljen stabilen odkup.
