Studies of the decomposition of fibre components in the biogas process by means of in-sacco-batch method
The substrates used in biogas plants are characterized on the basis of their biogas potential. The in-sacco-batch method is an approved method for animal nutrition which determined the digestibility of ingredients of different feedstuffs. The digestibility and the rate of degradation of plant components and fibre components in the biogas process are important parameters. The batch fermentation test for estimating the biogas potential of substrates has no significance in this regard. For the optimization of the biogas process the digestibility of fibre components plays an important role. In this paper the he in-sacco-batch method was adapted for the biogas potential tests. The method allows the characterization different fermentation additives in view of the digestibility of substrates.
