Produção de fios de poliéster a partir do Poli(Etileno Tereftalato) : análise de viabilidade.

Abstract

The current scenario of solid waste disposal becomes increasingly critical, causing damage to both the natural environment and human beings. Therefore, new alternatives for the disposal and reuse of these materials must be studied so that they can reduce the impact generated by them. Thinking about this, a project is proposed for the use of the polymer poly (ethylene terephthalate) (PET) in post-consumer situation, so that its reinsertion in the industry can be made viable, in the form of polyester threads, since it is a very raw material used in various branches of industry. The process is a strictly physical process, which basically involves prior preparation of the material, followed by your cleaning, grinding to reduce its size, making it technically feasible and offering better handling conditions, moisture control, submission at high temperatures and final preparations such as cutting and packaging in distribution packages. In order for the process to be considered viable and thus have its study and implementation phases continued, an economic analysis was carried out, taking into account expenditure on infrastructure, logistics, equipment, electricity, water, electricity and taxes. With such data, it was possible to obtain and verify economic indicators, which, as a rule, provide parameters that serve as a basis for decision making regarding the feasibility or not of a project. The values found for the indicators were a NPV of R$ 7,753,114.00, an IRR of 75% and an PI of 1.58, in addition to a payback of 2.41 years. In this way, the aim is to determine the feasibility of the project as a viable alternative within the natural environment and economic spheres.
