EnviTec's biological Service: Getting the best out of nature!

For your biogas plant, maximising efficiency is what matters.

The routine inspection of substrates and digestates is essential for the long-term biological maintenance of processes. No two biogas plants are the same and digestion is a natural process. Depending on input material quantity and quality, fluctuations are possible, which can be detected early on with a range of parameters, which let our Service Team take any action required in good time.

Our all-round service packages ensure the long-term flexibility of your plant.

We guarantee

  • High plant capacity utilisation
    On average, plants supported by our service teams achieve efficiencies of over 95%. This is all thanks to our experienced specialists, who use their expertise to extract the maximum yield from every plant. After routine site visits from EnviTec’s experts, significant improvements to performance are often seen in a matter of weeks, thanks to the fine-tuning of plant settings.
  • Less downtime
    Every hour of downtime translates into a major loss of earnings for your plant. Regular checks of the biological processes can detect aberrations at an early stage, however. This approach enables our teams to intervene earlier and keep your plant running smoothly.
  • Better profitability
    Our work – your profit! The efficiency of your biogas plant has a direct impact on its economic viability. Our specialists can draw on a wide range of tools to considerably improve the ultimate yield of your plant. This involves optimal fine-tuning of the substrates and digester systems.
  • A sustainable approach
    The regular inspection of input materials and digestate is essential for the long-term health of the digestion process. And the early detection of negative trends enables a proactive approach that can be effective in avoiding long-term problems with your plant – such as with gas production, for example.
  • Made-to-fit feeding
    Every biogas plant is different. Although a plant can experience fluctuations due to the input material used, and the quantity and quality of the output material, these can be detected early on during inspections by our experts. We help you to complete input material changeovers and optimise your feed management system, and can also make recommendations for the use of trace elements.

Our Lab for high-precision analysis

Das EnviTec Labor in Lohne

The EnviTec laboratory on Lohne / Germany


The formula couldn’t be simpler:
State-of-the-art lab tech + biological know-how = faster service

A properly working biological system is the basis for successful biogas production. Thanks to an in-house EnviTec lab, our experts can get results back from samples taken in just a few hours, and find out just how and where help needs to be provided.

Whether you have a service agreement or need an ad hoc callout because your plant’s biological systems have ‘gone off the rails’, our Service Team can collect samples from your facility for immediate analysis.

With 77 m3 of space, the laboratory rounds off EnviTec’s service portfolio by offering the following analyses:

  • Input materials used
    (dry weight, raw ash, raw protein, raw fat, raw fibre; calculated nitrogen-free extract (NFE))
  • Digestion process in digester
    (pH value, ammonium-nitrogen NH4-N, acetic acid equivalent (FOS), acid capacity (TAC); calculated FOS/TAC value)
  • End-of-process digestate
    (dry weight, raw ash, nitrogen, phosphorus, potassium, magnesium, calcium, copper, zinc, sulphur)

Our materials to boost you processes


Our biological additives keep the chemistry just right in your biogas plant

High-tech from nature itself: our biogas additives. At just the right dosage, products like EnviRed and EnVital do wonders for your plant and increase its long-term efficiency. Depending on your plant’s needs, we supply you with products for process stabilisation or performance improvement.

Our products are designed exclusively for use in biogas plants and adjusted individually to your feeder system. Whether or not you are using EnviTec components, any plant will benefit from our additives.

Simply call our Service Hotline today on +49 800 338 7777 to arrange a personal consultation.

Depending on your requirements, we support you with products for process stabilisation or performance enhancement of your biogas plant.

Biological maintenance services

More than made-to-measure: our Biological Service contracts

With us, there’s no such thing as standard. Our Biological Service experts offer a bespoke maintenance service. Specialist sampling plus the calculation and analysis of key figures are just as much a part of our service spectrum as the preparation of proposals for optimisation work. Our biological maintenance packages also benefit from a flexible contractual structure.

Your advantages at a glance:

  • Extensive expertise in research and development
  • In-house lab
  • Onsite visits to your plant
  • Detailed plant parameter report
  • Discovery of configuration errors
  • Service schedule reminders
  • Instrument inspection and/or calibration (e.g. gas analysis)
  • Free customer hotline
  • Free admittance to annual industry conference organised by EnviTec Biogas AG

Our biological service support is there to provide advice to keep your plant at the highest level of performance.
