Análise do processo e tecnologias na gestão da cadeia de suprimentos de plásticos no Tocantins

Abstract

Plastic represents a big passive for the environment and its incorrect disposal may aggravate the environmental pollution. Recycling plastics contributes to reducing the volume transported to landfills, as well as promoting the reuse of materials, and strengthening the circular economy. Technology transfer is essential to boost industries and promote a continuous flow of exchanges and knowledge. Thus, the objective of this research was to analyze the process and the technologies that exist in the management of the plastic supply chain in the State of Tocantins. The methodology approach included: qualitative and quantitative research, from the point of view of the problem; exploratory research, regarding the objectives; bibliographic and documentary research. The Methodi Ordinatio was used to construct a systematic literature review, analyzing articles that are relevant to the research theme. The literature review was written from the databases of Scielo, Science Direct, and Web of Science, with a portfolio of 42 articles from 2020 to 2024. The target audience for the survey was plastics companies in Tocantins, selected based on the National Classification of Economic Activities. Primary data were collected through documents available online, and secondary data were collected through a semi-structured questionnaire. After screening, 13 companies participated in the survey, comprising the representative sample.The research shows that most of them used the granulation and extrusion technologies, but predominating the mechanical recycling. It was found that the main challenges to the adoption of new technologies are related to limited financial resources and the lack of partnerships. In addition, the most accessible and relevant mechanisms for innovation, according to the respondents, are training, education, and technical consultancy. Strengthening public policies, financial incentives, and greater integration between the productive, academic, and government sectors are fundamental strategies to promote a more efficient and sustainable management of the plastics supply chain.
