23. - 25. January 2024

Progress in Manure and Digestate
International Online Conference


Conference Language: English

Things are happening – fermentation product use and processing as an opportunity.

We still face the social challenge of protecting ground and surface waters from nutrient inputs. This manifests itself, for example, in greater restrictions on nutrient use (key words: “red areas”, “yellow areas”).

At the same time, plant technologies continue to develop and once innovative processes are now almost a standard application, e.g. evaporation technology. Other processes are promising and offer tie-ins to industrial processes, but are still looking for the big breakthrough into the mainstream.

Where it’s all going? We don’t know. But we do know that you, as practitioners, researchers, equipment manufacturers or technology providers, are working on the topic, making future solutions possible. We invite you to present your work and/ or results at our conference.

Under the motto “Science meets practice”, we are organizing a 3-day conference that will focus on the latest scientific findings and successful examples of implementation.

In addition to the current state of the art, the main topics will include advances in the bioeconomy and sustainability, as well as outlooks into promising innovations and new research approaches.

Topics of the conference

  1. State of the art
  2. Bioeconomy, biorefinerie
  3. Climate-positive circular agriculture
  4. Biochar & pyrolysis: synergies in the biogas process
  5. Results & experiences from practice
  6. Occupational safety &amp health protection
  7. Innovations, outlook into the future
  8. Business forum

We look forward to receiving your submissions on any of the 8 conference topics. Deadline for abstracts submission is the 31. May 2023.

Acceptances or rejections regarding submitted abstracts will be sent in mid-July.

Why participate?

Overnutrification in many German and European regions requires specific technology to treat and upgrade manure and digestate.

The last couple of years have produced significant leaps and innovations to the upgrading technology and more possible business models have been explored.

Be one of the first to tackle this pressing challenge with background knowledge and the right technology.
