Gestão sustentável da cadeia de suprimentos hospitalar. Um estudo sobre como práticas ambientais levam à seleção de fornecedores médicos hospitalares

O tema de sustentabilidade ambiental tem se tornado cada vez mais um interesse nos negócios e, com a consciência crescente de práticas ambientais, a gestão na cadeia de suprimentos e seus impactos deixam de ser um problema restrito ao poder governamental e entra para a agenda das empresas, trazendo responsabilidade a todos que, de forma direta ou indireta, geram resíduos. Com participação de 8,8% do PIB em 2009, as despesas com consumo de bens e serviços de saúde cresceu com relação ao ano de 2008, quando representou 8,3%. Contudo, o setor saúde se constitui um importante consumidor de insumos e recursos naturais, gerando impactos, tanto na prestação da assistência, quanto ao longo da cadeia de fornecedores de produtos e serviços gerando cerca de 200 mil toneladas de resíduos sólidos urbanos por dia, que representa entre 1% e 1,5% dos resíduos gerados por uma cidade ou comunidade. Apesar de o tema sustentabilidade estar em voga ultimamente e, de diversos estudos terem sido feitos sobre o tema, ainda existem poucos fundamentos sólidos da relação entre investimentos em práticas ambientais e aumento de competitividade, principalmente na área de saúde, que é foco deste estudo. O objetivo geral desta dissertação será, então, entender como as práticas ambientais de fornecedores médico hospitalares são percebidas pelas instituições de saúde, tornando-os preferencias. Para isso, serão realizadas entrevistas, com abordagem qualitativa e de caráter exploratório, com coleta de dados realizada através de questionário e entrevistas com 6 instituições de saúde de grande representatividade no cenário nacional. Assim, a questão de pesquisa deste trabalho é: de que forma práticas ambientais são consideradas na seleção e gestão de fornecedores médicos hospitalares.

Natureza morta...edifício com vida: uma arquitetura sustentável para o Serviço de Verificação de Óbitos

Sustainability in buildings, while reducing the impact on the environment, contributes to the promotion of social welfare, to increase the health and productivity of occupants. The search for a way of build that meets the aspirations and development of humanity without, however, represent degradation of the environment, has become the great challenge of contemporary architecture. It is considered that the incorporation of principles that provide a sustainable building with careful choices of design solutions contribute to a better economic and thermal performance of the building, as well as functional and psychological comfort to its users. Based on this general understanding, this paper presents an architecture project aimed to health care whose the solutions adopted follow carefully the relevant legislation and sets his sights on the theme of sustainability. The methodology began with studies on the themes of verification service of deaths, sustainability and those application in construction developed through research in academic studies and analysis of architectural projects, using them like reference for the solutions adopted. Within the project analysis was performed a visit to the verification service of deaths in the city of Palmas in Tocantins, subsidizing information that, plus the relevant legislation, led to functional programming and pre-dimensional of the building to be designed. The result of this programming environments were individual records with information from environmental restrictions, space required for the development of activities, desirable flow and sustainability strategies, that can be considered as the first product of relevance of the professional master's degree. Finally we have outlined the basic design architecture of a Verification Service of Death SVO/RN (in portuguese), whose process of projecting defined as a guiding line of work four points: the use of bioclimatic architecture as the main feature projectual, the use of resources would provide minimal harm to the environment, the use of modulation and structure to the building as a form of rationalization and finally the search for solutions that ensure environmental and psychological comfort to users. Importantly to highlight that, besides owning a rare theme in literature that refers to architectural projects, the whole project was drawn up with foundations in projective criteria that contribute to environmental sustainability, with emphasis on thermal performance, energy efficiency and reuse of rainwater

Influência do lodo de ETE na massa para fabricação de cerâmica vermelha

The WTP produce many kinds of residue on your treatment stages, but the sludge is the more problematic from the final disposition point view. The actual rate of residue production deriving from technological evolution and the crescent population needs prevents the subtle equilibrium generation between consumption and recycling/reuse, creating problems of pollution resulting from inappropriate management of residues. Thus, is necessary achieve a new equilibrium between the grow from raw materials and energy and the residue generation. This equilibrium should be achieved by technical and economic feasibility of environmental supported models through recycling and reuse. The red ceramic industry stand out in residue absorption question as raw material due their clay mass heterogeneity, constituted by clay minerals and non-clay minerals with wide mineralogical variation, allowing residue inclusion which act like plastic or non-plastic materials, contributing to retain heavy metals contained in residues in the vitreous mass formed during the burning of the ceramic bodies. This work propose the study of the influence of incorporation of 25 wt.% sludge from wastewater treatment plant, according preliminary results, in the mass to produce ceramic bodies. The raw materials was characterized through chemical composition analyses by XRF, mineralogical analyses by XRD, thermal analyses by TG and DTA, Atterberg limits and thermodilatometry. Subsequently was composed the mass with 75 wt.% of clay and 25 wt.% of dried wastewater sludge from UFRN WWTP. Samples with 6,0 x 2,0 x 0,5 cm was produced with unidirectional compacting under pressure of 20MPa and burned in temperatures between 950 and 1,200ºC. After fired, the ceramic bodies have been submitted to physical and mechanical analyses through the measure of firing shrinkage, water absorption, density, apparent porosity and flexural strength; crystallographic analyses through XRD and microstructure analyses by SEM. The technological properties obtained was satisfactory to production of roof tiles with 25 wt.% at 1,200 ºC, but the production of others products at lower temperatures was not feasible

Estudo da viabilidade da utilização de cinza de lodo de esgoto como adição em argamassa de cimento Portland

The use of sewage sludge as a raw material falls within the waste recycling key in the current process model environmental sustainability .Waste recycling has been consolidated as a sustainable environmentally sound technical solution, and. Despite showing very variable composition and characteristics, sewage sludge, can be considered as a residue with a high recycling potential in the building sector. In this paper the feasibility of using sewage sludge ash was studied in addition to Portland cement mortar in 1:3 mass considered the standard dash. This gray additions were studied in proportions of 5%, 10 %, 15 %, 20 %, 25% and 30% by mass of cement. The methodology was focused on the characterization of materials by physical, chemical , mechanical , environmental and morphological followed by the production of mortar tests ,and finalized by the characterization tests of mortar in the fresh state, through the consistency index, content of entrained air, bulk density and water retention, and in the hardened state by bulk density, water absorption by capillarity capillarity coefficient, compressive strength, tensile strength in bending ,tensile bond strength and microstructural analysis for percentages of 0 to 20%. After comparing with the standard mortar mortars with addition of ash, it is concluded that the ash of sewage sludge did not impair the integrity and properties of mortars with addition, including increasing resistance to compression and tension, being 20% more indicated percentage. Thus, it becomes feasible the addition of sewage sludge ash in Portland cement mortar for the trait studied

Método de avaliação do gerenciamento de resíduos em canteiro de obras da construção civil : proposta baseada em empresas construtoras da cidade de Natal-RN

According to great concern between the developed industrial activities and resultant impacts over the environment, an association of several factors have occurred, procedures to the efficient management of the rotation between economical development and the environment have been improved. A research in field have been realized inside building sites of companies in order to provide knowledge about the implemented and accomplish actions according to the resolution from CONAMA nº307. Trough the interview among the representations of the companies and photographic survey in loco, such as, what makes the companies implement this management, reutilization and recycling, transport and disposition. The present study had as objective: analyze the insertion of the used tools to residuals management, proposing improvements, in a way that it can be easily identified during the procedures execution in the building sites of the building companies of the city of Natal/RN. To reach the goal, in the first place a revision of the pertinent literature was performed; there for, it can be seen the relation between residues management and environment sustainability, once it happens in a continued way it may prevent the waste and reduces the risk that the activities way bring to the employees, community and environment; once found the great difficult faced with regard to labors, material, equipment, project, planning, costumer s interference, furnisher. And still, it could be verified wich materials generate greater indexes of residues in the works and the main occurrences of waste and loss. However a greater transparency is needed coming from the high administration in the commitment with the continued actions, to make it so, there must be a cultural change inside the company. There for there will be a greater productivity and quality of the under taking such as costumer s satisfaction

Desenvolvimento de um sistema de indicadores de desempenho para empreendimentos em construção civil, utilizando a abordagem macroergonômica

This paper presents the validation of the Performance Indicator System for Projects under Construction - SIDECC. The goal was to develop a system of performance indicators from the macroergonômica approach, considering criteria of usefulness, practicality and applicability and the concept of continuous improvement in the construction industry. The validation process SIDECC consisted of three distinct models. Modeling I corresponded to the theoretical development and validation of a system of indicators. Modeling II concerns the development and validation of multi- indicator system. For this modeling, we used the Mother of Use and Importance and Multivariate Analysis. Modeling III corresponded to the validation situated, which consisted of a case study of a work of construction of buildings, which were applied and analyzed the results of modeling II. This work resulted in the development of an applied and tested for the construction of an integrated system of performance indicators methodology, involving aspects of production, quality, environmental, health and safety. It is inferred that the SIDECC can be applied, in full or in part, the construction companies as a whole, as well as in other economic sectors

Estudo dos parâmetros de extração de fenol de efluentes aquosos por um tensoativo não iônico

Environmental sustainability has become one of the topics of greatest interest in industry, mainly due to effluent generation. Phenols are found in many industries effluents, these industries might be refineries, coal processing, pharmaceutical, plastics, paints and paper and pulp industries. Because phenolic compounds are toxic to humans and aquatic organisms, Federal Resolution CONAMA No. 430 of 13.05.2011 limits the maximum content of phenols, in 0.5 mg.L-1, for release in freshwater bodies. In the effluents treatment, the liquid-liquid extraction process is the most economical for the phenol recovery, because consumes little energy, but in most cases implements an organic solvent, and the use of it can cause some environmental problems due to the high toxicity of this compound. Because of this, exists a need for new methodologies, which aims to replace these solvents for biodegradable ones. Some literature studies demonstrate the feasibility of phenolic compounds removing from aqueous effluents, by biodegradable solvents. In this extraction kind called "Cloud Point Extraction" is used a nonionic surfactant as extracting agent of phenolic compounds. In order to optimize the phenol extraction process, this paper studies the mathematical modeling and optimization of extraction parameters and investigates the effect of the independent variables in the process. A 32 full factorial design has been done with operating temperature and surfactant concentration as independent variables and, parameters extraction: Volumetric fraction of coacervate phase, surfactant and residual concentration of phenol in dilute phase after separation phase and phenol extraction efficiency, as dependent variables. To achieve the objectives presented before, the work was carried out in five steps: (i) selection of some literature data, (ii) use of Box-Behnken model to find out mathematical models that describes the process of phenol extraction, (iii) Data analysis were performed using STATISTICA 7.0 and the analysis of variance was used to assess the model significance and prediction (iv) models optimization using the response surface method (v) Mathematical models validation using additional measures, from samples different from the ones used to construct the model. The results showed that the mathematical models found are able to calculate the effect of the surfactant concentration and the operating temperature in each extraction parameter studied, respecting the boundaries used. The models optimization allowed the achievement of consistent and applicable results in a simple and quick way leading to high efficiency in process operation.

Avaliação do desenvolvimento sustentável na bacia hidrográfica do Rio Seridó em face das políticas públicas e da gestão dos recursos hídricos

The reality of water resources management in semiarid regions, such as the Seridó region, has been shaped by a complex chain involving social-cultural, political, economic and environmental aspects, covering different spheres of activity - from local to federal. Because water is a scarce element, the most rational way pointed out by our recent history has been to move towards an increasing emphasis on the need for a truly rational, integrated, sustainable and participatory water resources management, supported by legislation and by a network of institutions that could materialize it. In this sense, despite all the advances in the formulation of public policies in water resources, which ones have indeed lead to significant changes that have occurred or are underway in semiarid regions such as Seridó? What factors may be preventing the realization of the desires rationality embedded in the framers of water policies intents? How to properly manage water resources if the current actors who promote their management and the political, human, cultural and institutional processes that intervene in this management, show strong traces of unsustainability? The research methodology adopted in this paper led to a breakdown of the traditional approach to water resource management, to integrate it into other areas of knowledge, especially to political science and public administration, catalyzed by the concept of "sustainable development". From a broad, interdisciplinary literature review, an exhaustive characterization of the river basin Seridó, a set of interviews with key people in the public administration acting in the region, a series of diagnoses and a set of propositions were made in order to correct the direction of current public policies for the region. From the point of view of public policies, it is in the deployment phase, not in its formulation, which lies a major problem of the lack of significant progress in water management. The lack of coordination between government programs are well characterized, as well as the lack of efficiency and effectiveness of their actions. The causes of this secular model are also discussed, including political factors and social relations of production, which led to a stalemate difficult, but of possible solution. It can be perceived there is a scenario of progressive deterioration of natural resources of the fragile ecosystem and a network of environmental and social consequences difficult to reverse, the result of a persistent and inertial sociopolitical culture, whose main factors reinforce itself. The work leads towards a characterization of the water resources management also from the perspective of environmental, institutional, political and human sustainability , the latter being identified, particularly as investment in the development of people as autonomous beings - not based in ideological directives of any kind - in the emancipation of the traditional figure of the poor man of the hinterland" to the "catalyst for change" responsible for their own decisions or omissions, based upon an education for free-thinking that brings each one as co-responsible epicenter of (self-) sustainable changes in their midst

O turismo de base local como um possível indutor de desenvolvimento rural: uma análise da realidade e das potencialidades no distrito de dondo-moçambique

The current debate on rural development focuses on the territorial approach, recognizing the multifunctional character of rural areas. Emphasize the use of endogenous forces, the need of implement policies which valorize local specificities, the participation of social actors in revitalization of rural areas. In this context tourism enters as a means to induce a new dynamic to rural areas, since the activity is regarded as a channel for the upgrading of the natural and cultural resources and the rural way of life. This study focuses on local-based tourism as a promoter of rural development, giving an analysis of the social reality and potential for this tourism in the district of Dondo. In it, is proposed to analyze the potential for development of local-based tourism in the district of Dondo, assessing the extent to which local reality enables the inclusion of the community in the management of local tourism resources. For this, was showed the inclusion of local-based tourism in the current context of rural development, was identified and organized systematically the factors that influence the implementation of local-based tourism in the study area and was verified as far as possible the study area corresponds to the constraints identified, showing how local-based tourism can best been encouraged. Was adopted a qualitative methodological approach to both the procedures and data processing, but also by critical approach, using bibliographical research, semi-structured interviews that fell on the group of public administrators who work in tourism and community leaders. The critical analysis was based on the principles of sustainability o Sachs particular ecological, social, cultural, economic, space, beyond the analysis of political and institutional aspects. The survey results show that the district of Dondo has a potential for implementing a model of tourism development on a local basis, since it is rich in natural and cultural research, benefits from good network accessibility in the context of the market in the region, the population live according to their habits and customs and value their identity. There is also a good cooperation between community members, although not in tourism, a fact which is observed through the lever of community participation in associations, cooperatives, working in areas such as agriculture, fishing, environment, civic education etc. It also has public funding sources to augment or stimulate local investment. Despite obstacles such as inexistence of policies and local plans for tourism development, lack of awareness of tourism, lack of basic infrastructure, as well as equipment and facilities to support tourism, the results shows that these problems can be solved through a public commitment from both government, and community through a joint planning and participation

Fatores de sucesso ou insucesso do turismo ambientalmente sustentável : percepção das autoridades públicas no pólo costa das dunas do Rio Grande do Norte

This study aims to compare the thermal performance of tiles made from recycled material (waste packaging cardboard with aluminized film) with the tiles of fiber and bitumen, fiber cement and red ceramic with the aim of verifying the suitability of tile to be used in hot and humid climate of low latitude. The samples were selected according to the availability from Natal RN market, as they are sold to the consumers. The methodology was based on studies that used experimental apparatus composed of thermal chambers heated by banks of incandescent bulbs, to analyze the thermal performance of materials. The tiles in the study were submitted to analysis of thermal performance, thermophysical properties and absorptance, using chambers of thermal performance, measuring the thermophysical properties and portable spectrometer, respectively. Comparative analysis of thermal performance between two samples of the recycled material with dimple sizes and different amounts of aluminum were made, in order to verify, if these characteristics had some interference on the thermal performance of them; the results showed no significant performance differences between the samples. The data obtained in chambers of thermal performance and confirmed by statistical analysis, showed, that the tile of recycled material have similar thermal performance to the tile of fiber cement. In addition to these tests was carried out the automatic monitoring of a building covered with tiles of recycled material, to verify its thermal performance in a real situation. The results showed that recycled shingles must be used with technical criteria similar to those used for fiber cement tiles, with regard to the heat gain into the building. Within these criteria should be taken into account local characteristics, especially in regions with hot and humid climate, and its use must be associated, according to the literature, to elements of thermal insulation and use of passive techniques such as vented attics, ceilings and right foot higher
