To safeguard the future of peatlands as carbon and water reservoirs, the FAO MICCA (FAO 2012) and the the German National Academy of Sciences Leopoldina (statement 2024), for example, recommends that drained areas should be rewetted and managed by paludiculture, i.e. that the wet or rewetted peatland soils should be used for agriculture. Accordingly, the rewetting is part of the 'Natural climate protection action program' launched by the German federal government in 2023.

However, rewetting has as result that the areas are then dominated by different plant species such as reeds, sedges, reed canary grass, woody plants such as black alder, or herbs such as fever clover and valerian.

Currently, there is still a lack of practicable and profitable models for a changeover to peatland-conserving or peatland-preserving management.

ATB is working intensively on solutions for peatland protection and has, among other things, worked on ways to produce biochar as a substitute for peat.

At present, research in several projects (see below) is focusing in particular on developing, jointly with users, strategies and solutions for management methods adapted to high water levels and on establishing commercially viable, attractive utilization options for peatland biomass in regional value chains.

In the sense of a cascading biomass utilization, the main focus is on a material utilization that promises a higher added value with a better climate balance compared to an energetic utilization. 

ATB can draw from decades of experience in the field of technology and process development for plant fiber production, for example from hemp or nettle, and uses its expertise and infrastructure to adapt established processes on the one hand and to develop new solutions for the special raw material-specific requirements of paludiculture plants on the other.

Fen crops can be processed into a wide variety of sustainable products, such as organic building materials, peat substitutes for gardening substrates, litter pellets, papers, packagings, or even disposable dishes. The raw material is provided by the biomass of sedges, calcareous rushes, reeds, Typha (bulrush), reed canary grass and a number of other crops.

Preliminary research carried out by the working groups "Process Engineering for Fiber Crops" and "Process Enginering for Energy Crops" at ATB and the resulting product samples are very promising.
