Axpo Kompogas Ltd Flughofstrasse 54 8152 , Switzerland
Since Mar, 2015
Our vision
Our aim is to exploit the potential of all organic waste to generate cost-effective and sustainable energy.
Our Mission
Our mission helps us fulfil our vision
- We are the technology leader in the construction of fermentation plants for organic waste.
- We specialise in operating fermentation plants for sustainable material recycling and energy recovery of organic waste in Switzerland.
The Kompogas process
The patented Kompogas process is based on the continuous dry fermentation of organic waste using a plug-flow digester. The fermentation process is both thermophilic and anaerobic. In this kind of dry fermentation, the temperature in the digester is maintained at 55°Celsius. The average substrate moisture is around 75% and the retention time is approximately 14 days. The Kompogas process ensures that the organic waste is degraded properly and freed of undesired spores, germs and micro-organisms.
The continuous-feed, horizontal plug-flow digester facilitates a high gas yield and offers high operating reliability thanks to the simple and efficient control systems. A low-speed agitator ensures the optimum formation of methane. The special design and arrangement of the agitator paddles also prevents sedimentation of dense media materials in the fermentation substrate.
Fermentation involves various upstream and downstream processes. Via a feed unit, the organic waste is fed into the digester for treatment. Subsequently, the substrate is automatically conveyed to the digester. A discharge pump withdraws the hard substrate. Around one-third of this substrate is pumped back for inoculation. The remaining quantity is either pushed out of the digester or mixed with green waste using the partial flow process.
Advantages of fermentation
From waste management to resource management
Fermentation of solid organic waste turns waste management into resource management, while still assuring the material recycling of organic waste. The sanitised digestate obtained from the fermentation process is used as wet or dry natural fertiliser, or is refined to form compost. This way, a closed, environmentally friendly natural cycle is maintained.
All organic, biodegradable waste can be used as feed material for the Kompogas process. Green waste and food leftovers from municipal waste collections provide the right mixture for the ideal fermentation process and the recovery of energy.
Research and development
Across the globe, more than 70 fermentation plants use the Kompogas system. Collectively this adds up to more than 450 years of operational experience. The first Kompogas plant went into operation in 1991. Even today, this plant boasts 100% operational reliability. This is the best possible proof of the durability and reliability of our plants.
Drawing on the experience gained from operating our own plants and from close collaboration with operators abroad, we are committed to continual development of our technology, using our innovative strengths to enhance and modify processes and components.
