Resumo: |
This study aimed to investigate domestic organic waste, wood and smuggled cigarette tobacco residue biodegradation in five facultative reactors. In order to monitor the process, physicochemical (pH, temperature, humidity and the C/N ratio), biological (germination test) and spectroscopic (UV-Vis and IR) analyses were carried out. Besides that, the wood waste granulometry influence and the proportions of tobacco waste added were investigated. The best results were obtained for the proportions 10% and 40% (volume) of smuggled cigarette tobacco (SCT) mixed to wood waste chip (WWC) sized 20 and 40mm. The C/N ration analyses and the phytotoxicity tests revealed that the compound reached maturity within a period of 120 days of processing in the 5 reactors. The spectroscopic UV-Vis and IR pointed to the efficiency, indicating the compounds of simpler structures degradation and the formation of more complex groups (humic substances). In the metal analysis, it was observed that the concentrations are in agreement with the maximum permitted by the lows for the solid compound. Thus, it was concluded that the proposal of treating the waste under study through the facultative reactors was efficient. |
