Organização do leiaute e do fluxo produtivo de empresa de gerenciamento de resíduos de equipamentos elétricos e eletrônicos

Abstract

The objective of this research was to analyze the implemented management forms in the company, case study, which carried out the disassembly, decharacterization and treatment of WEEE in Vale do Rio dos Sinos, Rio Grande do Sul. For the development of this study it was necessary to organize, complement and analyze the data segregation of provided by the company. To meet the specific objectives related to mapping of the post-consumer chain related to the company, to the company's mass balance. While in order to propose improvements in the layout and productive flow, measurements were taken in the building and on-site analyzes to later apply Muther's methodology (1978). When mapping the company's post-consumer chain, it was identified that 75% of the generators that dispose WEEE with the company were located in the Bacia Hidrográfica do Rio dos Sinos (BHRS), focused in the cities of Novo Hamburgo and São Leopoldo with 52 % and 14% of total waste, respectively. The economic activities that generated the most waste, among those sent to the company were those related to the manufacturing and trade industry, with a share of more than 25%. When company’s mass balance was perfomed, it was identified 88% of WEEE, 9% of class II B waste - non-hazardous - inert and 2% of class I hazardous waste were collected. After the residue segregation, it was verified that the company shipped 71% of class II B waste, 26% of WEEE were left intact (without disassembly) and 3% were waste class I. Among the WEEE, it was found that brown (11%) and green (83%) lines were the most representative, as metal (84%) was among class II B residues, which presented the highest amount among the discarded items by the company. After the WEEE’s segregation, there was an increase of 470% in class II B waste. Through the Systematic Layout Planning (SLP) methodology, a reorganization of the production flow and a proposal for improvements were made to the company's layout, for which increases were achieved in the storage areas of 17% for WEEE, 16% for Class II B waste, 215% for televisions and screen monitors. It is concluded that the methodology used in this study was suitable for the development of improvements of company layouts, since it was possible to demonstrate that with the reorganization of the internal areas a better flow in the productive process was obtained.
