- Many years experience with CHP-units and biomethane feed-in systems
AD and biomethane plants by Agraferm
- Agraferm, as a provider of complete anaerobic
digestion (AD) plants, has comprehensive knowledge and many years of
experience in the national and the international biogas sector. Put this
know-how to good use by utilising our entire biogas value chain.
Our plants stand out for...
- ...High reliability and maximum plant availability
- ...Lots of gas in little space: Highest gas yields at low container volume (1.5 MWel from only two containers)
- ...Use of high-quality, robust components such as digester, agitator and pumps, thus increasing life span
- ...An especially stable fermentation process
- ...Industrial quality plant construction
- Minimal operating costs
- Highest possible feedstock flexibility
- Minimal risk of failure
- Maximum economy and low energy consumption
Maximum load fermentation for best gas yields
- Biogas operators around the world have to work with a
great variety of feedstocks, and this often places high demands on the
Agraferm started working on high-load fermentation of energy crops very
early on. This maximum load (high-load fermentation/digestion) technology
developed and supplied by Agraferm offers AD plant solutions to cope with
very high viscosities without having to challenge operational reliability,
flexibility and gas yield – whereas conventional plant technologies have to
reckon with high dilution, process energies and wear.
That is why Agraferm plants are regularly rated among the top performers,
for example, in the German Federal Government's KTBL measuring programme and
BMPII biogas measuring programme.
Our paddle agitator stirs everything!
- With the development of the robust paddle mixer – which
has been successfully used in Agraferm plants for more than a decade –
Agraferm has brought the continually changing selection of input materials
While conventional AD plants with submersible motor agitators have to work
primarily with slurry, maize or sugar beet, operators of Agraferm AD plants
can choose from a wide selection of feedstocks. In an increasingly limited
and depleting feedstock market, operators of Agraferm plants can accept
feedstocks that other plants can use only in limited amounts, or cannot use
The Agraferm paddle mixer allows stirring and recycling of input materials
with a high dry content and richly structured materials such as poultry
manure, green waste, organic waste bin contents, silages etc. in high
From biogas comes biomethane - gas upgrading
- A cutting-edge technology that will play a major role in
the future is the processing of biogas into biomethane of natural gas
quality, otherwise known as renewable natural gas (RNG). This process makes
the development of heating concepts redundant, and thereby opens up entirely
new alternatives in the choice of Location and allows gas-to-grid. Agraferm
has already realised many Projects with gas upgrading in the biomethane
Agraferm biomethane (gas-to-grid) plants are based on membrane technology.
This successful solution employs only membranes that have proven successful
over time. Agraferm assumes responsibility for the entire process design and
construction of the plants.
Many years of experience in waste-to-energy
- The Agraferm Group has comprehensive expertise in waste
treatment, and can process and recycle virtually all input materials that
contain organic material. The subsidiary BTA International GmbH in
particular is responsible for this segment.
Since 1984, BTA has been the leading specialist for wet-mechanical
pre-treatment of all kinds of organic wastes with subsequent wet
fermentation for generating biogas and quality compost (or material similar
to compost, according to the kind of waste).
Wet-mechanical pre-treatment in the BTA process allows great flexibility in
the input materials and offers superior efficiency and selectivity in
separating out impurities. This process results in stable and reliable
fermentation operation, minimises costs for disposing of impurities,
maximises biogas yield and ensures the quality of the digestate.
Research & development in the field of biogas
- The Agraferm Group is an active driver behind
developments in the field of microbiological and technical biomass
pre-treatment and recycling.
We undertake innovative research projects with partners from science and
industry, with the results being tested in practice, discussed among experts
Control technology for AD plants: Agracontrol
Our "agracontrol green" control software and technology, which was developed
in-house, is unique and can be used for small and mid-sized AD plants as
well as industrial scale plants. It brings together all of Agraferm's
essential experience in the automation of processes and production of
“agracontrol green” controls the following processes for you:
- All important parameters relating to the input and timing of feedstock
- Monitoring and documentation of filling levels
- Automation of pumps and mixers
- All data presented comprehensively on screen
- Visual presentation ensures timely recognition and rectification of possible process malfunction
- Monitoring of gas quality and automatic notification of faults via transmission to a remote unit
- Safety and economy for biogas plants
We do not desert our customers when the construction of their biogas plant
has been completed. We offer you a comprehensive range of technical and
biological follow-up services. Ranging from the supply of spare parts to the
complete running of your plant. As our customer, you can choose which
services you need according to your requirements.
The Agraferm service strategy covers the complete spectrum of services for
Agraferm specialists and a hand picked service network, form a team, which
numerous customers have relied upon for many years. Whether you are a
newcomer to the world of biogas or an expert our training courses, given by
our experienced staff, will provide you with all the information you need to
operate successfully in this field.
Bioprocess service for AD plants
- The Service division of Agraferm Technologies AG offers
solutions tailored to each individual AD plant. The Service Team records all
relevant operating data and maintains a clear overview of your AD plant as a
whole as well as the feedstocks used.
The biology has to be just right – only the combined action of reliable
technology with a stable bioprocess in your digester can guarantee optimal
utilisation of your AD plant. For every AD plant operator, it is extremely
important to know the status of the AD plant, the quality of the feedstocks
and the state of the bioprocess at all times.
Based on analyses and our many years of experience, we create a specific
test report and evaluate the individual results for you.

Experience in supervising plants from other manufacturers
- Micro nutrient solution with essential trace elements
To produce biogas as efficiently as possible – that is the aim of every
biogas plant operator. The greatest reserves when running an biogas plant
are in the speeding up and stabilisation of the biological process as well
as the utilisation of the energy potential available to the fullest
The deciding factor in the success of an biogas plant is a well functioning
biological process. Optimise the bioprocess of your plant to the maximum
Complex micronutrients activate the bacteria in your biogas plant to give
the highest performance!
Whether it is a large or a small plant, using mono-fermentation or with
slurry – the micronutrients from Agraserv, a quality brand for service
products from Agraferm Technologies AG provide the best nutrients for the
bacteria in your biogas plant.
