Resumo: | The search for final alternative destinations for residue from industrial processes is a growing problem. Pulp and paper industries generate large amounts of residue, which are not always reused or do not receive an adequate destination. An alternative is its reuse, using the final disposal of the residue in the soil, for its potential to inactivate part of the chemical compounds, allowing its use as agricultural inputs of low cost. The purpose of this study was to analyze the final residue of the wastewater treatment plant of a pulp and paper industry. Industries in this economic sector produce high resistance and low lignin cellulose pulp and recover the chemicals used, reducing costs. In order to pre-evaluate this disposal possibility, this study carried out the classification of the waste classifying the hazardousness of the cellulose fiber, and its behavior under solubilization and leaching tests. The results of the analysis showed the potential of solubilization of substances in water above the maximum permissible value (MPV), characterizing the residue as non-inert and non-hazardous Class IIA. This fact implies that safety doses must be evaluated before its application in soil. Further studies must be carried out in terms of toxicological effects and its potential to be applied to crops. |

A busca por destinações finais alternativas para os resíduos de processos industriais é uma problemática crescente. As indústriasde papel e celulosegeram grandes quantidades deresíduos, que nem sempre são reutilizados ou não recebem a destinação adequada. Uma alternativa é seu reaproveitamento, utilizando a disposição final do resíduo no solo, pelo potencial do mesmo em inativar parte dos compostos químicos, possibilitando seu uso como insumos agrícolas de baixo custo. Este estudo teve por finalidade analisar o resíduo final da estação de tratamento deefluentesde uma indústria de papel e celulose. Indústrias deste setor produzemuma polpa de celulose de alta resistência e com baixoteor de lignina, alémderecuperar os químicos utilizados, diminuindo custos.De forma a pré-avaliar esta possibilidadede disposição, este estudo realizou a classificação do resíduo classificando a periculosidade da fibra de celulose, e seu comportamentosob ensaios de solubilização e lixiviação.As análises conduzidas demonstraramcaracterísticas de solubilização de substâncias em água acima dos níveis de valor máximo permitido (VMP), caracterizando o resíduo como não inerte enãoperigoso Classe IIA. Isso significa que doses seguras devem ser estudadas antes de sua aplicação no solo. Estudos adicionais devem avaliaros efeitos toxicológicose o seu potencial na agricultura.
