Sažetak
In Varazdin City (a town in the north of Croatia), mixed municipal waste was collected, mechanically treated, baled and stored from 1st April 2005 until its final disposal. Dissolved organic carbon (DOC) concentrations were tested for 12 years. The problem is that several complex physical, chemical and biological processes take place in the baled waste for bio-waste, which was then an integral part of mixed municipal waste. To solve this problem, the experimental values are used, and they determine the dependence of the DOC concentration on time, as well as the transition points and events that cause the abrupt changes in the decomposition of the organic component in mixed municipal waste. Unlike the landfill in the baled waste, after aerobic phase begins the anaerobic phase, and after anaerobic phase begins again aerobic phase, because the foil gas permeability is starting. The whole process is, according to System Theory, a complex system with many components, and the interaction, connections, and interdependencies among them, but also the interaction with the environment of the system. The main result of the paper is the conceptualization and parameterization of such a system, helping to describe and understand this system, but also to predict and manage it.
