Biogas

Increased methane yield

Biomass from energy crops or vegetable waste is used in biogas plants in order to obtain methane gas as a source of energy through microbial degradation. The yield of the fermentation process and the cost-effectiveness of the plant depend to a very high degree on the type and quality of the substrate resources used. The stability of the fermentation process is also an important factor.

In the interest of efficient and stable fermentation, it is advantageous for the energy crops to be processed beforehand in order to achieve extensive defibration and a defined maximum particle size. This significantly facilitates the microbiogical process. For this purpose, we have developed our Biogrinder of type RBG. It produces a crushed and mashed substrate forming a flocculent mass. The machine generates very high shear forces in the input material. It features crushing tools of simple design which provide a long service life and easy maintenance.

Investigations in collaboration with universities show that the methane yield can be significantly accelerated through use of the BHS Biogrinder. A further advantage is homogenization of the substrates. In addition, the formation of floating layers is avoided. Extraneous material such as stones and soil clods are also crushed in the machine. Another attractive option is that of using low-cost vegetable waste; without pretreatment, however, it is difficult to add this to a fermentation process. Profitability of the investment can be achieved within a short time.
