Aplicação do software OpenLCA na avaliação do ciclo de vida de embalagens e recipientes plásticos na empresa Topack Moçambique

Abstract

This paper is a case study in which high-density propylene (HDPE) and low-density propylene (LDPE), produced by the Topack companies, were analyzed in terms of their environmental performance. analyzed in terms of their environmental performance. The life cycle analysis method was adopted here. The boundary of this analysis was established from the acquisition of the respective raw material, its transportation, processing and disposal. material. OpenLCA, an open source software, was used for this purpose, in different categories of permitted impact. The study was carried out by standardizing 1000kg of bags of LDPE and 1000 units of HDPE. For the conditions under study, there was a proportional increase in impacts with the increase in the quantity processed, the incineration fraction and for the recycling fraction of the two polymers. Only the abiotic depletion of fossil fuels was influenced in the study of the origin of the raw material for both polymers. The results obtained in this study highlighted there is a need to take measures to slow down the rate of environmental degradation environmental degradation caused by the rampant production of synthetic plastics and the adoption of sustainable measures. These measures could include the pyrolysis of plastics, the production of diesel, biodegradable plastics and innovating the process of incineration.(TRADUÇAO NOSSA)
