Topic & Goals

The aim of the project is the development of an innovative two-stage process for the mono-digestion of chicken manure. The challenge of fine sand removal will be solved within the first stage of the process. Toxic ammonia concentrations will be avoided by shifting the balance between ammonia-ammonium in the direction of ammonium through the pH reduction by means of CO2 control within the second stage. The lab-scale tests are a pre-requisite for the implementation in pilot-scale and concept development for a demonstration plant. The upscaling of the process will be carried-out considering economic and ecological aspects.
