### Composts Characterization and Discriminant and Correlations Analysis
The second function explained 19.67% of the variation and separated the green wastes of both urban wastes evaluated in the work. In both functions, the separation was mainly based on respiratory indexes, the fecal coliform group and holocellulose degradation. This indicates that both the origin of the waste to be treated and the sanitation and stabilization operations during composting were fundamental to generate composots of agronomic interest. \begin{table}

Table 3: Properties of final compost from industrial composoting facilities *. [PERSON]'s correlation analysis is shown in Table 4. This analysis provided a deeper understanding of the factors that affected the sanitization and stabilization of the biomaterials. As expected, the proliferation of fecal contamination indicator groups in compost was a clear symptom of the presence of fresh organic matter; therefore, of detectable phytotoxicity in GI or by respiratory (RDI and AT4). Although very few articles have evaluated this relationship, there is literature that corroborates the results obtained [47]. On the contrary, when the consumption of the holocellulose fraction was increased, products that promoted plant growth were generated (R\({}^{2}\) = 0.56). This value indicated that the consumption of nutrients present in the residues was not only intense, but also served to produce stabilized composts. In short, although parameters of different nature were used, the results showed that, despite the intrinsic difficulties of industrial-scale composting to ensure optimal composting conditions, it is possible to predict and manage the process to correct the deficiencies of the starting raw materials. \begin{table}
