The University of Kassel has designed an IFBB demonstration plant. It fits into two standard containers in order to facilitate European wide transportation. This prototype includes all of the core elements of the IFBB process.
The pre-treatment of the silage is conducted by a mash water percolation system at a temperature of 40 °C. Mechanical dewatering of the mashed silage is carried out by a screw press. The resulting press fluid can be converted to biogas by anaerobic digestion in any biogas plant. Briquetting is done with a hydraulic briquette press with a throughput of 40-110 kg /h. Production of pellets would also be possible.
"We are working in the area of bioenergy for a long time now. For twenty years we are processing bio waste of the city and utilise the energy here at the sewage plant. We missed a opportunity to apply a similar method for green cut."
"My profession is waste sewage water treatment. I wouldn't say, I'm doing environment engineering or bioenergy, I'm saving the world. That sounds just ridiculous! But people have to deal with what it is."
