With Fermentation to sustainable recycling of biogenic waste

The bio-gas production using a fermentation process in the PÖTTINGER fermenter is based on the discontinuous dry fermentation of biogenic waste (organic waste and municipal waste as well as organic residues) whilst excluding oxygen.

This produces CO2-neutral methane. This in turn can be converted into green electricity and heat or into natural gas quality bio-gas or can be used as fuel (LNG) for commercial vehicles. This can save fossil fuels.

The process also accelerates the composting. Instead of going through the principal rotting phase, the organic waste is filled into the fermenter boxes with a working volume of ca. 45 m³. Then bio-gas is created in a fermentation process.

The remaining material is further processed into compost in a post-rotting process and can be used as humus fertiliser.

In contrast to simple disposal and combustion of organic residues, the recycling in a PÖTTINGER fermentation system completes the material cycle both in economical and ecological terms.
