The TOPKO-project

Dr. Michael Röhrdanz is a research assistant and coordinator of the TOPKO project (peat-free, climate-friendly plant substrates made from hydro- and pyrolysis char). In the TOPKO project, the University of Oldenburg, in collaboration with the peat factory Moorkultur Ramsloh Werner Koch GmbH & Co. KG and Floragard Vertriebs-GmbH, is pursuing the goal of producing gardening substrates by using mixtures of compost, biochars (Pyrolysis) and/or hydrochars (Hydrothermal Carbonization) for tree nurseries. 

Mr. Röhrdanz is responsible for the overall coordination of the project and is conducting plant growth trials with the newly developed char-compost substrates.

Duration: 06/2024 – 04/2027
