## 4 Discussion  
Since almost double the minimum number of respondents answered the questionnaire and the statistics displayed using SmartPLS 4 showed that the model presents consistency, the discussion is relevant, once most of the respondents have a background in engineering or administration, courses in which concepts related to macroscopic properties and management are covered in greater depth, or chemistry, which provides microscopic notions of the properties of plastics. A more specialized respondent public, daily involved in the production of plastic and its waste management, is desired to reproduce the methodology in future studies on waste management but including the collection of the position and the time of experience in the area. A semi-structured questionnaire version--which presents not only multiple-choice questions but also open-ended ones--is an additional resource, as respondents would see a greater interaction since they could present opportunities for improvement of plastic waste management in their own words. It is also worth noting that researchers in qualitative research are moving away from conventional approaches and embracing creative methods, including videoconference interviews [58] and chatbot surveys [59]. The importance of this is that a high participation of the target public can enhance the findings and contribute to a more comprehensive understanding of the subject. So, from the final results, the following paragraphs discuss the implementation of the results. In this paper, the methodology has been applied to the Brazilian metropolis of Salvador. Concerning the indicators of the effectiveness construct, most of the respondents considered the volume of processing to be slightly more significant than the market maturity for the effectiveness of plastic waste management, which in turn contributes to performance, as linked to business profitability. This is in line with Adekomaya [26]. However, the market maturity was also judged by them to be significant, which is in line with the study by [PERSON] et al. [60], in which market immaturity is pointed out as a barrier to sustainable plastic waste management. Once the positive influence of effectiveness on performance has been verified, the maturity of the plastics waste market contributes to more investments in sorting technologies. As the market maturity and volume of processing are reflective indicators of the effectiveness construct, the greater the maturity, the larger the plastic waste volume that can be processed (i.e., recycled). These two indicators also contribute to the increase in both the recycling rate and business profitability, reflections of performance. \begin{table}
