Biogas production from organic matter is a natural process, the closer one follows the natural processes with industrial ones the better the results tend to be. When technical systems work against nature, they tend to become complex resulting in excessive wear and tear as well as failures in plant operation. RENERGON therefore uses minimal but robust key components to support and enhance the natural processes. Measurable synergistic effects are the result: stable biogas production, low wear, low energy consumption and the associated low life cycle costs with a long plant service life and availability.
In the case of solid fermentation as the core technology (patented RSD® process – Renergon Simultaneous Digestion), the process liquid, the percolate, is circulated and thus the decomposition process of the stackable biomass in the fermenter boxes into biogas is started and maintained. This percolate cycle ensures that relevant microorganisms, moisture, heat and essential nutrients are evenly distributed in the biomass. In addition, the percolate with its buffer substances stabilizes the entire biogas process. Due to the robust plant technology and the stable anaerobic (without oxygen) degradation, impurities, foreign bodies have little impact. In contrast to a large liquid fermenter holding say 400 cubic meters of liquid digestate which has become chemically contaminated and then needs to be emptied. Emptying and disposal of such volumes is time-consuming and extremely expensive and it does happen.
As a technology leader in the field of solid fermentation, RENERGON stands for maximum plant safety, optimum process sequences and high gas yields.
