Efficient and Carbon-Neutral Operation of Biogas Plants
The operation of biogas plants is complex, and today numerous companies specialize in the design, supply, and construction of core process technologies. However, there are several important, technology-independent components that can significantly improve the efficiency and carbon-neutral performance of a biogas facility.
How Can Altherm Help?
- Automated feedstock feeding, preparation, and pre-grinding
- Provides the stable process heat required for optimal fermentation.
- Safe pre-storage and post-storage while preserving material quality and composition.
Altherm provides innovative renewable energy solutions to address these challenges through proprietary technologies and partnerships with leading international companies. Many are unaware that the market value of biogas and biomethane can be influenced by whether the process heat is generated from renewable energy sources.
Feedstock Preparation
Biogas from Straw
Through the collaboration between the Danish companies Linka and Euromilling, a unique, fully automated system can be configured to process straw from baled feedstock to a homogeneous material ready for fermentation.
- Automatic Straw Feeding and Bale Twine Removal System
- High-Capacity Straw Shredder and Hammer Mill
- Pre-Grinding and Homogenization Mixing Tank
- SCADA-Based Control System
The energy-efficient design, low maintenance requirements and fully automated operation ensure cost-effective performance. The technology has already proven its reliability in practice: at the Nature Energy Kværs biogas plant in Denmark, 4 tonnes of straw are processed every hour, delivering stable and high biomethane yields.

Stable Process Heat
Carbon-Neutral Heating Solution
Our outdoor, stand-alone bale-fired heating systems require no dedicated boiler house and are available in outputs ranging from 200 to 800 kW. Multiple units can also be installed in cascade to meet higher heat demands. As a carbon-neutral heating solution, the system supports sustainable energy production, while the resulting ash can be mixed with slurry and returned to agricultural land as a soil amendment.
The Altherm T Series is a complete bale-fired heating plant, as it includes not only the boiler but also…
- …all mechanical equipment…
- The buffer tank
- The double-walled heat-recovery chimney
- The complete control system
- The ventilation system
The Altherm T Series bale-fired boilers offer a reliable renewable energy solution for delivering the stable process heat essential for efficient biogas plant operation.
Safe Pre- and Post-Storage
Flexible Solutions
With more than 55 years of experience, Wiefferink has proven its flexible, enclosed solutions across a wide range of applications worldwide.
The AB Cover is an innovative air-supported cover system with a double-membrane design and a large, adjustable gas storage capacity. It integrates seamlessly into biogas plants, providing an ideal solution for efficient gas storage and process reliability.
The Floating Cover is a floating membrane cover system that rests directly on the surface of the slurry. As it does not increase storage capacity, it is generally not considered a building permit–requiring installation.
Silocover, új vagy meglevő hígtrágyatároló tartályok ammónia-visszatartását, szagkibocsátás-csökkentését és az esővíz kizárásával kapacitásvédelmet célzó, egész Európában elterjedt, kulcsrakész lefedési rendszer.
Ecobag is a flexible, enclosed storage system with a capacity of up to 10,000 m³, designed for slurry storage and as a buffer tank for biogas plants.
