ANAEROBIC DIGESTION & RESOURCE RECOVERY
Our RSD® technology starts where conventional liquid biogas plants and plug flow systems reach their limits. Dry fermentation, on the other hand, allows the fermentation of dry and fibrous substrates (dry matter: 20%-55%), which often cause problems in other systems.
The process runs in batch mode and provides a continuous biogas yield. The plants consist of several digester boxes (garage digester), which are filled and emptied in a fixed cycle. The manual effort required is extremely low, since apart from the simple loading and unloading activity, pre-treatment of the substrate (shredding, shredding) is rarely necessary. In addition, the substrate is not being moved during the entire retention time (18-21 days). The failure and maintenance costs of the technology are reduced since no sensitive stirring and pumping technology is used (avoidance of floating and swelling layers).
One of the most important advantages of dry fermentation is the low demands on the substrate. This can contain impurities that remain as residues after the process and is less dependent on particle sizes as well as fiber content. As an example, consider domestic biowaste, which often contains residual materials such as packaging materials, or horse manure with horseshoes or holsters, which can cause great damage to stirrers.
The biogas produced can then be directly converted into electricity or processed, as biomethane or bio natural gas, and fed into the gas grid or used as vehicle fuel (CNG).
WHICH WASTE IS SUITABLE?
Organic waste is widely underestimated worldwide from an economic and ecological point of view. RENERGON transforms this broad spectrum of material into value. This gives our customers an economic and technical edge. The following substrates are relevant:
BIOWASTE
GREEN WASTE
MSW (household waste)
AGRICULTURE WASTE
ANIMAL HUSBANDRY WASTE
SLAUGHTER BY-PRODUCTS
INNOVATIVE BIOGAS TECHNOLOGY
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 Anaerobic Digestion 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.
FROM WASTE TO VALUE
We focus on our customers. You choose a profitable investment through the production of renewable energy, fuel, compost, fertilizer and biochar as well as through proceeds from waste disposal and generated CO2 compensation certificates.
Biogas is a versatile energy source that can be transported and stored. In addition to generating electricity and heat using a combined heat and power unit (CHP), it can also be processed into bio-methane (bio natural gas). It is then fed into the natural gas grid, used as fuel (CNG) for cars, trucks and buses, or filled into gas cylinders and sold to industry/commercial or private households.
