“…The complexity of this process is determined by the dynamic interactions between biological, chemical and physical mechanisms occurring within highly heterogeneous compost matrix (Fontenelle et al, 2001;Sole-Mauri et al, 2007). From bioengineering point of view, temperature, is one of the main factors, which has the greatest influence on the composting process and its final composition, followed by other strongly connected key parameters such as C:N ratio, oxygen concentration, pH, moisture content of the substrate, particle size and porosity (Boniecki et al, 2012;Bongochgetsaku and Ishida, 2008;Mengchun et al, 2010;Seng and Kaneko, 2011;Schaub and Leonard, 1996). Due to wide range of environmental variables, it is challenging to control composting process, thus, the framework integrating important elements of this biological system should be developed.…”
