Product Portfolio
  • 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

    Your benefits
    • 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 agitation equipment.
        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 under control.
        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 at all.

        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 concentrations.
      • 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 sector.
        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.

        • 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.
