Reciclagem ambiental de embalagens cartonadas: métodos e desafios na destinação sustentável

Abstract

Recycling of carton packaging, widely used for food and beverage storage, represents an environmental challenge due to its multilayer composition of paper, plastic, and aluminum. This study investigates methods for recycling these packages, focusing on obtaining the aluminum present in the material through chemical processing with sulfuric acid. The methodology involves laboratory experiments for separating the packaging components and analyzing the efficiency of the obtained aluminum sulfate as a flocculating agent in water clarification tests. The results indicate that prior separation of the materials, especially through the hydrapulping method, significantly contributes to the feasibility of the recycling process. The study reinforces the importance of integrating innovative technologies in solid waste management, contributing to the circular economy and environmental sustainability.
