Biotechnological Partition of the Grass Silage to Streamline its Complex Energy Utilization

The current prevailing energetical utilization of grass silage is based on anaerobic fermentation. However, huge fermentors and long retention times are needed because only a part of the organic matter undergoes the anaerobic fermentation. System of complex energetical utilization of the grass silage based on partition of easily accessible organic matter was verified on a commercial scale. It was confirmed that the separation of the accessible organic matter from the ballast enables minimization of the anaerobic fermentor dimensions from thousands to tens of cubic meters and reduced retention times from months into hours. In addition, the waste energy obtained from the cogeneration of the methane was used to run the overall technology and the charcoal kiln to produce charcoal from the ballast.
