The Eigenbetrieb Umwelttechnik of the city of Baden-Baden (Baden-W\u00fcrtemberg, Germany) operate the first full-scale implementation of the IFBB process. The production of silage started in February 2013, whereas the hydro-thermal conditioning and belt dryer units have been operational since June 2013. In Baden-Baden the IFBB technology is applied as an add-on to an existing sewage works and biogas plant (left). It is part of an integrated environmental concept of waste management for the city and its urban hinterland. The plant is designed with a production capacity of 2100 tons of silage briquettes per year, whereas the biogas plant offers a capacity of 1.3 MW electrical power. The plant processes a wide variety of substrates: branches, brushwood, leaves, grass, all kind of garden waste, municipal green waste, etc. The first processing steps are to separate, chop and sieve the delivered material. Green clippings and small woody particles are ensiled and pressed into hermetically packaged 500 kg silage bails (right). This allows easy storage and transport to the biogas plant, approximately 2 km away from the delivery station.<\/p>\n
At the site of the biogas plant the core of the IFBB process starts. The silage is conditioned (= mashed) with warm water (approximately 40\u00b0C), and then the material is mixed within the pulper (left). The cell walls of the fibrous parts of the silage are opened during this processing step.<\/p>\n
In order to keep the suspension suitable for pumping, 4 cbm water is added per 1 cbm silage. Subsequently the biomass-water mixture is pumped into two buffering reservoirs (right), where the suspension is homogenized again.
