Hofstetter AUTTONOMOUS - Off-Grid Landfill Gas Management Systems
Auttonomous – our complete, integrated and self sustainable solution for the management of off-grid landfills.
An impossible challenge
The management of off-grid landfills represents a special environmental challenge as landfill technologies such as degassing systems and leachate treatment plants rely on electricity for operation. The operation of such landfills therefore comes with very high risks of explosion, fire, intoxication and groundwater contamination, as well as with increased odor emissions.
The complete off-grid system
Hofstetter is proud to introduce its latest innovation called Auttonomous ™ – the first ever solution that is capable of managing the gas and leachate of off-grid landfills. The fully integrated and containerized Auttonomous ™ unit safely combusts landfill gas in a gas engine which produces electricity and heat that can be utilized on-site.
Part of the produced electricity is used to power a compact reverse osmosis unit that turns landfill leachate into clean water. Last but not least, the proper gas and leachate management results in significantly decreased odor emissions.
- Gas flow rate 20 – 500 Nm3/h
- Efficiency >70% (combined thermal & electric)
- Methane concentration 35% - 55%
- Leachate treatment 4`000 - 20`000 liters per day
- Turn down ratio 1:5 (1:10 optionally available)
- Noise level : <69 dB (A) (special low-noise design optionally available)
