A Influência da qualidade das aparas na reciclagem do papelão: um estudo de caso

Abstract

Among all kinds of paper packaging, the ones which are manufactured with corrugated paperboard are the most commercialized all over the world, cause their features can bring a great protection to lots of different kinds of products. Besides that, they're 100% recyclable and their parings have good commercial value. So, the collective consciousness is a fundamental point when talking about the importance of the whole logistic which involves this process, including: collection, segregation, classification and dispatch to recycling companies, so that these actions can boost employment and income generation as well as the environment preservation, through the natural resources extraction decrease and residues generation during the paper manufacturing process and it can also avoid the wrong destination of this recyclable material to landfills. Inside the recycling chain, each one who is involved, being them ordinary citizens, pickers, co-ops, paring professionals and the recycling companies, has a very important role. Face to everything presented here, this workpaper aimed to show the importance of the parings quality control sector in a recycling company, and point these actions efficiency or possible irregularities, as the mix of other kinds of paper different from paperboard and the presence of impurities as plastic and metals. The applied methodology consisted of getting a relation between the quantity of acquired paperboard parings with its levels of moisture, impurities, prohibitive materials and other kinds of paper, describing all steps, from the reception to the analysis made by quality sector, based on the whole year of 2021. Besides that, face to the evidence found by this sector, to point the company taken actions in relation to loads which showed non-compliances. Inside the paper manufacturing process, quantify the generated residues and the costs with management. From the carried out survey, some commercial dealings between the company and paring professionals in relation to non-compliant loads, caused their devaluation, and it could be avoided through a better selection, avoiding any contamination with impurities and the mix with different kinds of paper. In total, about 2,253 thousand tons of parings, suffered actions as disqualification, controlled use and return, due to these non-compliances. The quantity of residues was straightly connected to the quantity of parings, where about 13 thousand tons were generated among plastic, sand, stones and small metals as screws, nails, clips and sludge. In relation to the costs with transport and destination of residues, it was spent about $ 1.8 million. It can be concluded that despite of recycling is a very important process in the pressure attenuation on natural resources extraction, there are still some factors to be considered for this chain improvement, and environmental education is the key to success.
