O controle estatístico do processo como ferramenta para verificação do comportamento da resina PET reciclada na indústria alimentícia : uma revisão bibliográfica

Abstract

The increasing evolution of the use of plastics in several industrial segments in recent years has led to some concerns, one of which is the negative impact it causes on the environment. In order to reduce this damage, a approprieteed global application of selective collection is necessary, which aims to combat these impacts generated by the incorrect isposal of plastics. As a way of solving the problems generated by the consumption of plastic in the environment, several food industries have invested in the use of recycled resin as plastic packaging due to its good mechanical properties and generation of circular economy. However, there are some challenges that can hinder the use of this recycled packaging, such as changes in the intrinsic characteristics of the material, presence of contaminants, changes in optical and mechanical properties. In this context, the objective of this work is to carry out a survey of the main problems faced by the use of recycled PET resin in food packaging in the industry, as well as to show means that can be used to mitigate these impacts, as a statistical process control tool that performs the measurement and control of a manufacturing process.
