RESUMO

The acquisition, installation and operation of an urban waste treatment normally are very expensive to satisfy legal requirements. The AAA system has the goal to be self-sufficient by using all the waste through the commercialization of quality products, without polluting and instead, creating profit. On the other hand, the commercial simulation systems are complex and a long training time is necessary in order to master their use. By using simple and accessible mathematical modeling as a tool to simulate the AAA system, it is possible to quantify, as in real life case, what could be expected at each implementation step. Starting from scratch, from the simplest block diagram, it is possible, by simulation step by step, to have a glimpse of how much money can be gotten from treated waste to quality products commercialization. The modeling starts as simple as possible, to see how it works, then, progressively adding capacities as necessary. To understand the complexity of a cleaning system, different configurations are studied; simulating the performance for hypothetical data, in order to have an idea of how much material is necessary to reject to get a desired cleanness in the real world, based on cleaning equipment selectivity. The mathematical model, developed in Excel chart, permits immediate use by entering the local data, to simulate the expected money profit from the commercialization of locally demanded products. The model is open and flexible, so it can be adapted to different situations and it can be completed in progressive form. A case study (Ribeirão Preto) was the first application with real data.
