Service and Optimization of Existing Feed-in Technology in Biogas Plants
Repowering, retrofitting, and custom-fit replacement parts—for fewer downtimes. More stable feed. Higher performance from existing systems.
Many biogas plants do not fully realize their potential. Increasing requirements, changing substrates, and growing wear and tear lead to a decline in performance, efficiency, and operational reliability. Through targeted measures in the area of feed technology, we improve existing plants cost-effectively without the need for a complete rebuild.
Where, specifically, can your insertion technique be improved?
Typical weaknesses in existing biogas plants usually manifest in several areas at once: declining throughput, rising energy consumption, increasing malfunctions, or high wear and tear. It is crucial to identify the actual cause and tailor the feed-in technology specifically to address it.
Higher throughput with stable feeding
Reduce Energy Consumption and Control Operating Costs
Minimize disruptions and reduce downtime
Which measure will have the greatest impact on your system?
Not every plant requires the same approach. Some problems arise from worn-out components, others from mismatched systems or changes in the substrate. That is why we always consider existing feeding technology in the context of all processes working together.

Repowering
Modernize existing facilities in a targeted manner and overcome performance limitations.

Retrofit & Conversion
Targeted optimization of individual systems and components.

Maintenance & Replacement Parts
Reduce wear and ensure system operation.
Practical Solutions Instead of Standard Solutions
Our solutions are based on real-world plant experience. We understand the typical challenges associated with difficult substrates, fluctuating feed rates, and existing third-party systems. Our goal is always to ensure stable and cost-effective plant operation—tailored to actual operating conditions.
Let's work together to identify where your feeding technology has the greatest potential for optimization.

FAQ
Frequently Asked Questions About Service and Optimization of Existing Biogas Plants.
When does it make sense to optimize or retrofit my feeding system?
Optimization is worthwhile if throughput decreases, malfunctions increase, or equipment wear is higher than average. Often, the substrates used also change over time, so existing systems must be adjusted to ensure stable and efficient operation once again.
What is the difference between retrofitting and repowering in terms of installation technology?
During a retrofit, specific individual components—such as those that are outdated or worn out (e.g., push floors, screw conveyors, or disengagement systems)—are replaced or modernized. Repowering is a more comprehensive process aimed at strategically increasing the performance, cost-effectiveness, and energy efficiency of the entire plant.
How can the application technique be adapted to new or more challenging substrates?
When switching to fibrous or heavier substrates such as manure or grass, we specifically equip the system with adapted disintegration technology and robust augers. This prevents clogging, reduces wear, and ensures a continuous flow of material.
How long will the plant be shut down during a retrofit or repowering?
Our goal is to reduce downtime to an absolute minimum. Through precise advance planning and custom-fit components, many modernization measures and component replacements can be carried out during already scheduled maintenance windows or in phases.
When will the investment in optimizing an existing feeding system pay for itself?
Modernization usually pays for itself quickly: Thanks to the more efficient technology’s lower electricity consumption, lower maintenance costs, and a higher gas yield resulting from more stable feed, retrofit measures often pay for themselves within the first one to three years.
