Worldwide
World’s theoretical
potential rises
according to a study published by the ATEE with 750 TOE/year if all
waste were treated through anaerobic digestion in discharge or
digesters – a value for which it is necessary to add the agricultural
by-products of a value of 1000 TOE/year. Overall, biogas represents a
layer comparable with the fossil natural gas worldwide consumption -
1800 TOE/year
In France
Energy likely to be developed starting from anaerobic digestion of household waste, of industrial effluent and wastewater treatment plants sludge seems to be evaluated between 2,6 and 5 million tep/year - more than 10% of the current gas consumption.
Worldwide ressource in biogas*
| World biogas ressource | Produced biogas (TOE/year) | Biogas
which can be valued (TOE/year) |
| Urban and industrial solid waste | 750 | 60 to 100 |
| Urban and industrial waste water | 50 | 40 to 50 |
| Agricultural by-products | 1000 | 40 to 150 |
| TOTAL | 1800 | 140 to 300 |
| Biogas/worldwide consumption of natural gas | 100% | 8% to 17% |
*According study of ADEME
Biogas ressources in France*

| Urban wastewater treatment plants | 65 000 | 150 000 |
| Industrial wastewater treatment plants and agrifood industries | 64 000 | 800 000 |
| Discharges | 19 000 | 300 000 |
| Anaerobic digestion of domestic and assimilable solid waste | 1 900 | 1 000 000 |
| Agricultural digesters | 100 | 1 000 000 |
