all-in-one provider

Full service from the beginning

We support you with personal full service and high-quality all-in-one solutions. Thanks to the many years of experience of our teams, we implement your orders quickly, flexibly and customer-oriented. Your personal project manager supports you in all details – from the first idea to the successful realisation of your biogas plant and beyond.
Consultancy & design
We focus on the safe and economical operation of your biogas plant. That is why detailed advice is particularly important to us: We take the time to listen actively and to question the requirements. Only when we know your requirements will we develop individual concepts that are exactly tailored to your situation. This is the only way to achieve the best possible efficiency of your plant.
Planning of permits
For fast procedures and short decision-making paths, we support you in all permit planning – from the official permit for the new construction or extension of your biogas plant to applications in the areas of building law, the German Immission Control Act or permits according to water protection regulations. Thanks to our many years of cooperation with authorities, we answer your questions quickly and professionally.
Plant construction
Sustainability, efficiency – e.g. by short construction times – and optimal technology are paramount in the design of your plant. We not only use sustainable building practices and state-of-the-art control software, but also take current trends and technologies into account. A lead engineer from PlanET will accompany you on site during the entire construction phase. For a smooth expert inspection, you will receive a detailed documentation.
You can rely on our full service at any time – from planning to completion. For an optimal start, you will receive a detailed technical briefing and we will also create plans with which you can reach full load operation as quickly as possible. Later, we will also support you in the ongoing optimisation of your plant, both biologically and technically – for the best possible biogas yield. Our other services include the professional maintenance of your plant as well as support for expert inspection.
We are happy to keep you up to date with our training courses in various areas. In addition to operation training, we also regularly offer lectures on current topics with changing speakers. In addition, we invite you to “Open Plant Day” as well as excursions to present new products and enable a regular exchange through the networking of plant operators.

Our answers to your questions

The time required to operate a biogas plant is approximately 1 hour per 100 kW.

For a 75-kW biogas plant, for example, the following quantities of substrates are required:

  • Cattle slurry: 28m3 per day
  • Cattle manure: 10t per day


Indicative values for the annual production of slurry/manure by cattle, young cattle and horses:

  • Cow or cattle slurry: 28m3 per year
  • Cow or cattle manure: 18t per year
  • Bull/young cattle slurry: 10m3 per year
  • Bull/young cattle manure: 9t per year
  • Horse manure: 14t per year
  • Biogas plants offer a long-term perspective, real value creation and sustainable management, because the residues generated in agriculture such as slurry and manure can be converted into valuable energy in the form of gas, heat and electricity with biogas plants.
  • Due to the high nutrient content, the fermentation residues produced during fermentation are ideal as organic fertilizer.
  • Self-consumption of electricity from the biogas plant has become increasingly attractive in recent years also for biogas plant operators, who can still claim a comparatively high buy-back price.
  • Counting post-digesters as storage space: Taking into account the input materials, residence times and the respective degradation efficiencies of the substrates used, post-digesters can assume up to 70 percent of the total volume as storage space.

In order to feed biogas into the gas distribution system, it must be upgraded beforehand. Since biogas is compatible with fossil natural gas, it can be used by means of existing pipelines and storage facilities regardless of where and when it is produced.

  1. Biogas/biomethane is renewable:
    Biogas/biomethane has one of the best life cycle balances. It saves several million tonnes of CO2 every year: in the heat market, in electricity generation and when used as fuel.

  2. Biogas can be stored:
    Biogas is almost the only renewable energy source that can be stored. The natural gas grid is available for this as well as the existing natural gas storage facilities. Generation and use can be decoupled in time and space – this offers significant economic benefits.

  3. Biogas is flexible and efficient:
    With biogas, electricity can be flexibly generated in CHP plants. Bio natural gas can be used 100 percent in the heating market or as an admixture in a flexible proportion. Processed biogas can also be used as fuel. Biogas is also available as balancing energy.

  4. The infrastructure is available:
    Processed biogas can also be transported over long distances via the well-developed natural gas grid. There are no economic costs for transport or storage.

  5. Biogas enables value creation:
    Biogas creates added value in rural areas. The production of biogas or biomethane has created jobs – not only in agriculture, but also in plant construction, in suppliers and service companies, in trade and distribution, and in the operation of CHP plants. Production of biogas and biomethane brings further valuable contributions to rural regions. Thus, value creation takes place almost exclusively in rural areas in the immediate vicinity of the plant. The raw materials produced – sugar beet, maize plants, waste and residues from agriculture – are often transported to the biogas plant over only a few kilometres. The residual digestate that remains after the fermentation of these raw materials is fed back into the agricultural production cycle as fertilizer.
