Recycling of organic waste

Energy recovery
Fermentation is a biodegrading material process in an oxygen-free atmosphere (anaerobic). The resulting methane-based raw gas is captured specifically, and used for energy. After treatment, it is fed into the gas network as biogas, or it is converted into green electricity and heat in a cogeneration unit.

Material recovery
After fermentation and energy recovery from organic waste, solid and liquid fermentation residue - natural fertiliser - remains. In agriculture, the natural fertiliser promotes growth of plants. This closes the material cycle. The Kompogas natural fertiliser and soil improver are completely sanitised. These quality products help achieve exceptional harvest results.

Fermenting and composting
Composting occurs with the addition of air, by contrast to fermentation (aerobic). The residue is compost. In classic compost heaps, there are always some anaerobic processes as well. This produces greenhouse gases, which are released into the environment and pollute it.

By fermenting organic waste, we contribute to reducing greenhouse gas emissions.

Construction of the new plant in Zurich has begun
09.08.2012

From 2013 onwards, the City of Zurich will collect and ferment organic waste before using the generated biogas as an environmentally friendly, renewable energy source. The plant will be built by Axpo Kompogas AG as general constructor. Monitor the progress over the Internet through our live webcam.

Axpo Kompogas increases agitator technology

Axpo Kompogas continues to increase its agitator technology and has therefore installed a complete measurement technology to its latest digester in Switzerland. The results will be used to develop the agitator technology for the new generation of digesters. More

 

 


Announcements

The Kompogas plant in Chavornay uses organic waste and saves CO2

The new Kompogas plant in Chavornay (VD) begins operation on 20 June 2011 and will immediately start to feed power from biomass, the new renewable energy source, into the public grid. The system uses around 20,000 tonnes of organic waste annually, and from it produces heat and organic fertilisers as well as green electricity. On Saturday, 25 June 2011 it is officially opened together with the local population.
