Advantages of anaerobic digestion
Anaerobic digestion involves a considerable reduction in the
organic
load, thanks of the biological reactions, and the polluting load of the
digested sludge. It is thus, a complete depollution. A correctly
controlled anaerobic digestion leads to very high rates of purification.
It also has other advantages:
Economic advantages:
- Additional income
- Autonomy in heat in a context of increase in the cost of
fossil energies
- Diversification of outlets for crops
- Reduction of manure purchase thanks to valorisation of
digested sludge
Agronomic advantages
- Transformation of the liquid manure and the manure into a
fertilizer, more easily assimilated by the plants, with reduction in
the odours and the disease-causing agents
- Organic waste processing for competitive prices
- Insect ellimination at the storage pit
- Odours supression
Environmental advantages
- Biogas resulting by anaerobic digestion is a source of
renewable energy because it replaces fossil energy
- Reduction of pollution due to nitrogen stripping (please
refer to the “Sludge” heading)
- Sustainable management of organic waste
