The BIOFerm system creates biogas from organic waste 30 to 40 per cent of the volume of residential waste in Germany is organic waste. The nationwide collection of biowaste offers enormous potential. This waste can be converted to energy in biogas plants at minimal cost. The largest as yet untapped potential lies in the field of biowaste and landscape conservation material. These elements have so far been to a large extent composted or sent unsorted to landfill sites instead of being used to generate energy. Waste is a resource – as part of the economic cycle BIOFerm offers a comprehensive range...

BIOFerm process – modern waste treatment Dry fermentation for stackable, organic solids Schmack Biogas offers the BIOFerm dry fermentation technology in its portfolio for non-pumpable feedstock. The demands made on the source material are extremely low. The process is ideal for stackable, organic solids, such as biowaste, green matter and solid manure containing up to 60 per cent dry matter content. Common features of industrial or municipal biowaste include: high proportion of impurities (plastic, wood, metal etc.) high dry matter content heterogeneous substrate composition not always separated...

Biowaste fermentation technology Recycling waste – the BIOFerm system Dry fermentation: ideally suited The BIOFerm system works on a batch process, which means that the digesters are periodically emptied and then refilled. In the reception hall a wheeled loader mixes the stackable fresh material with the previously fermented material (a process also known as „seeding“) and feeds it into the garageshaped digesters. After approx. four weeks the digester is completely emptied and refilled with a seeded mixture. for organic and green waste The majority of the plant and measurement technology is located...

Economic benefits from tried and tested technology Greater returns with robust and reliable components Dry fermentation technology is constantly evolving in terms of efficiency, ease of maintenance and economic viability. A great many tried and tested components from the Schmack wet fermentation system were transferred to the BIOFerm system as a result. Technical adaptation Garage digester roof structure Optimised drainage system Percolate tank as round fermenter with double membrane roof External gas storage Optimised roof structure The digester‘s roof has no housing, following the design of...

Flexible substance handling thanks to combined technology Integrating different biogas technologies enables the maximum exploitation of all source materials In conventional biowaste fermentation, the source substrate is extremely heterogeneous. Furthermore, the material input varies according to the season. The expected gas yields from biowaste are therefore highly variable. Hybrid system: Tried and tested technology, new process benefits Since not all biogenic residues are suitable for dry fermentation, they have to be used in socalled hybrid systems (combined wet and dry fermentation). The combination...
