This paper describes the experimental heating power measurement of biodegradable waste (BW). The goal of this paper is to describe the experimental measuring device and to present the results used in the “Vývoj technologické linky pro zpracování BRO pro přímé energetické využití Multiferm” project. The used measurement is based on controlled removal of heat energy produced by reacting batch material (BW) while maintaining optimal reaction temperature inside the material. These results helped to identify the processes inside the input batch material. Described experiment was sufficient to determine the produced heat power of the input material batch for the device design (project Multiferm). However tests will be repeated for various input material and various humidity for the academic research purposes. This can be performed on the measuring system which is fully functional after described two experiments.
