Estudo de caso: aplicação do método DMAIC-White Belt- na redução de latas amassadas em uma produção de leite em pó

This work consists of the implementation of the steps Define, Measure , Analyze , Improve and Control ( DMAIC ) to develop a Six Sigma project in an industry the food industry. The objective was to demonstrate a potential for reducing the occurrence of crushed cans in potting milk powder industry in a White Belt project. The food industry accounts for about 9 % of Brazil's gross domestic product ( GDP ), generating thousands of jobs . Among the major sectors of the food industry is the manufacturing sector of milk , occupies approximately 10 % of the total turnover of the food industry . Brazil is considered today one of the eight largest producers of milk powder in the world. The milk powder is packed , mostly for aluminum cans that are lined internally with varnishes and other materials to protect the milk of metals from aluminum. When the cans are dented food protection is compromised and may lead ingestion causing dis-eases such as botulism. Aiming to solve the problem of dented cans methodology was used as a case study with a quantitative approach through the DMAIC method. Some quality tools used in each step of the project as brainstorming , cause and effect diagram , flowchart , ef-fort and impact matrix, 5W1H , among other Pareto diagram is presented . A survey about the disposal of cans in the company verifying a mean loss and, from this histor-ical , a goal loss was calculated was performed . With the target set we calculated the annual saving design . During application of DMAIC was found that the highest rate of loss occurred in transportation between the factory and the factory that fills cans milk . Several actions were taken to resolve problems that resulted in dented cans and the first two months of phase control it was found that the smaller losses calculated target resulting in a saving for the company. The short time of implementa-tion of the Improve phase did not allow a more detailed a ...

Reciclagem de poliestireno expandido: compósito com fibras de algodão para a confecção de placas de circuito impresso

In this work polymeric composites reinforced with cotton fibers, from the textile industry, were developed in order to manufacture printed circuit boards. It was used expanded polystyrene (EPS) as a thermoplastic matrix by melting it. For the obtention of 10% and 15% of fiber volume fraction in cotton fibers composites, it was used wasted cotton fibers as an incentive of recycling and reusing of the domestic and industrial wastes as well as for Expanded Polystyrene(EPS). The mechanical properties of the composites were evaluated by tensile and flexural strength from standardized test methods. Composites were characterized by a Scanning Electron Microscopy (SEM), Thermogravimetry (TG/DTG), Differential Scanning Calorimetry (DSC) and dielectric analysis. The analysis of the results showed that fiber in the composite directly influenced in the thermal and mechanical properties

Análise da dinâmica do uso da terra e sua interferência em enchentes na área urbana do município de Americana (SP)

Due to an intense process of population growth and urban density in Americana (SP), mainly due to the development of the local textile industry after 1970, there was, concomitant to the occupation of the margin of rivers and streams, soil sealing that increased the level of superficial runoff, triggering frequent floods. Based on the analysis of these processes we investigate the conditions of one densely urbanized area of the county, the Córrego do Parque, in three time series, 1977, 1996 and 2008. Taking as the starting the characterization and spatial distribution of landscape physiography, we prepared thematic letters and synthetic maps digital scale 1:10,000 from photointerpretation of aeroframes. The thematic maps were produced by scanning with subsequent edition using the software Auto-Cad Map. Checking the data and of geographic coordinates with GPS (Global Positioning System). Regarding land use classes, we used the description of the Soil Conservation Service (1975) which allowed us to get the Curve Number parameter, which will be used in hydrologic modeling for verification of flooding (Tucci, 1989). For the process of hydrologic modeling, we used models based on Methodology Object Oriented Modeling Applied to Water Resource Systems, Viegas Filho (1999), using the computer program called IPHS1, which uses models of the Soil Conservation Service (SCS , 2004), for conversion of rainfall-runoff and the spread of excessive rain. The results indicate that increased waterproofing generated by the change in use and occupation over the past decades promoted the increased surface runoff and drainage system overload, increasing the intensity of floods

Biorremoção de corante direto de efluente industrial simulado utilizando levedura liofilizada

One of the most primal ways of human work already known is the tessellation and ginning for the production of fabric and clothing - what used to be, back in those days, statement of power and status. The arrival of the Industrial Revolution - in the middle of the XVIII century at Britain - increased the textile industry production, and what used to be manufactured and hard to obtain, starts then to be produced in mechanical ways and large-scale. Despite all the boost given to the economy of an expanding capitalist market, it should be pointed out the consequences of this major industrialization, especially the environmental ones, more and more concerning nowadays. The emissions of waste - that sometimes could be toxic - in effluents can possibly contaminate the aquatic ecosystems, causing a huge damage to its fauna and flora, affecting therefore all the biodiversity, reaching inclusively the humans. To avoid these problems, a few strategies have been taking place in the attempt to eliminate - or at least reduce - the amount of dye found in the effluents, and as the textile industry constantly leaves waste, efficient methods - that present good results in a short period of time - with a low cost are needed. The present study will test the bioremoval capacity of yeast (Saccharomyces cerevisiae) in contact with dyes in a fix concentration, diluted in water with three different pH values. The tests will be done duplicate, and after the concentration analyses - made by spectrophotometry - it will be analyzed which pH shows major efficiency in the dye removal and what is the influence of the biomass in this process

Estudo da utilização de serragem de madeira como adsorvente para o tratamento de efluentes têxteis

The Brazilian textile industry has been a highlight in the global economy. Connected with this high economic performance there is the water consumption and the generation of great volumes of wastewater which present high concentrations of dyes and chemical substances. One of the main techniques used in the treatment of textile effluents is adsorption, which has the activated carbon as the main adsorbent. Recently, studies have been developed to find alternative materials to activated carbon and exhibiting good adsorption capacity of dyes. The aim of this work is to study the potential of sawdust as adsorbent of low cost to remove the dye Direct Green 26. The results of this type of dye removal were obtained through the study of adsorption isotherms obtained by spectrophotometry in the UV-visible region analyzed by the Langmuir model. Finally, a comparison was made of these results with those of other adsorbents. Results showed that the average removal of dye, using sawdust, was 78.8% for an initial concentration of 500mg / L and the maximum adsorption capacity of 119mg / g. These results demonstrate the great potential of sawdust as an adsorbent for the dye Direct Green 26.
