Elaboração de um plano de gerenciamento integrado de resíduos sólidos no restaurante universitário da Universidade Federal do Rio Grande do Norte

The concern about preservation of the environment reaches different layers and sections of global society. The environmental prior quality of our planet can only be reached through changes in the attitudes taken in relation due to the waste generated by society, this also lead involving the education sector, in example of the Superior Education Institutions where the concept of ambiental management needs to gain a growing space.In the Federal University of Rio Grande do Norte, can be found the Universitary Restaurant as an example of a Food and Nutrition Unit, it is a restaurant destined to provide services to the academic comunity with the production and distribution of meals. In this operational context the work itself aims subsidies and funds to the search of as minimal generation of residues as possible, applying environmentally correct processes and practices. The work was developed in the period of September to October of 2009 in the Universitary Campus of Federal University of Rio Grande do Norte, in the Universitary Restaurant of the referred institution. The project involved all the employees of the restaurant and used like method the action survey. The produced waste was characterized, arranged according with it s nature (organic or inorganic) classificated following the NBR ISO 14004, adapted by Kinasz (2004) that adjusts the Standards to the specific reality of Food and Nutrition Services being diagnosed an expressive amount of produced waste in the Universitary Restaurant, it can be assured that a culture of wasting is very present and exists, contributing to the rise of solid residues, damaging the environment and consequently reflecting in the costs and expenses of the Unity, a known fact that characterizes and justifies the need of a promoting and active action that leads to positive reflexes in the economic and environmental area, drafting a Plan for Integrate Management of Solid Residues on the Universitary Restaurant of Federal University of Rio Grande do Norte

Gerenciamento de resíduos sólidos recicláveis: estudo de caso das cooperativas do município de Natal/RN

This dissertation conducted in the years 2011 and 2012, an analysis of cooperatives waste pickers in the city of Natal, Rio Grande do Norte, aiming to identify improvements to be implemented to assist the management of waste from the municipality as well as to improve the living conditions of the workers who perform the selective collection, the environmental perspective. This analysis was performed by means of an investigation of the reality in which they live cooperatives and their local representation, using also the law. The research is characterized as a case study of an applied nature, documentary, consultations with the institutions related to the issue of solid waste in the national and local levels; exploratory and descriptive, the main methodological tools technical visits and structured interviews.

For the analysis of data matrices were used to include comments and method GUT, from which it was possible to identify numerous difficulties faced by recycling cooperatives, and develop proposals for possible improvements in various aspects of their operation, such as infrastructure and production process , which can improve both the waste management and the quality of life of workers involved in the selective collection system city

Panorama dos resíduos sólidos urbanos nos municípios de pequeno porte do Brasil

The panorama of Urban Solid Waste (USW) in Brazil, in general lacks information, given the immensity of the country. However, it is from available data that the public executives should define the USW management. To contribute to the choice of a model for the management of USW in small municipalities, this study reviews the related literature, showing an overview of the final disposal of USW in small municipalities. Several data and researches are discussed, concluding that the available data, despite being provided by the public managers, who often attenuate the problem, should be considered for the proposition of policies to encourage the waste treatment

Desenvolvendo e gerenciando compostagem de resíduos sólidos urbanos: para geração de renda e repasse de tecnologia à acrevi

Nowadays, as well as in the past decades, the dumping of biodegradable organic waste in landfill is common practice in Brazil, as well as in most parts of the world. Nevertheless due to its rapid decomposition and release of odors, this practice hamper’s the operation and implementation of a recycling system. These facts encouraged our research to find an efficient system for the management of organic waste, not only for the use of official workers responsible for managing these wastes, but also for non-governmental institutions. The Recycling for Life Community Association – ACREVI (Associação Comunitária Reciclando para a Vida), together with the municipal authorities of Mossoró-RN, Brazil, have assumed the social role of collecting and recycling solid waste produced by most of the local population. However, it was observed that the organic waste it collected was not receiving any treatment. This present work aims to make compost with mixed waste (green waste and organic household), and then do chemical analysis of the material in view to use the waste as organic fertilizer. The objective being: to share the knowledge acquired by putting it into a very simple language accessible to people with little education. The experiment was conducted at ACREVI, Mossoró (RN), and the compost was obtained following the method "windrow", forming three cells (I, II, III) with conical shape, dimensions of 1.6 meters and 2.0 meters in diameter for cells I and II, and 1.0 meters high and 2.0 meters in diameter for cell III. The process was accompanied by analysis: CHN elemental, a variation of cell temperature, humidity, pH, TKN, bulk density, nutrients and heavy metals. Stabilized organic compounds reached the C/N ratio of 10.4/1 cell I and 10.4/1 in the cell II in the cell, showing how good soil conditions, with potential to improve the physical properties of any soil and pH acid soils, has presented the cell III at the end of the process the C/N 26/1, is a high ratio may be associated with the stack size III, thus changing the optimal conditions for the occurrence of the process. The levels of heavy metals in the analyzed compounds were lower than those established by the SDA normative instruction, Nº 27, of 5 June, 2006. The use of pruning trees and grass are used in small-scale composting, while generating a quality compost in the final process, it also created an important condition for a correct sizing of the composting piles. Under the studied conditions it is not advisable to use cells with a height of 1.00 m in height and 2.00 m in diameter, as these do not prevent the rapid dissipation of heat and thus can not be a good product at the end of composting. The composting process in the shed of the association and the preparation of the primer enabled the development of an alternative technology to generate income for members of ACREVI.

Gerenciamento dos resíduos sólidos dos serviços de saúde: aspectos do manejo interno no município de Marituba, Pará, Brasil

Os resíduos sólidos dos serviços de saúde (RSSS) oferecem risco potencial para saúde pública e meio ambiente perante um gerenciamento inadequado. Objetivou-se verificar aspectos do manejo interno dos RSSS do município paraense de Marituba. Através da aplicação de questionários e visitas de campo, realizou-se um estudo descritivo, observacional em treze estabelecimentos de saúde. O volume total de resíduos gerados era de cerca de 13.000kg/semana. Havia limitações nas diversas etapas do manejo interno, como a realização de tratamento interno somente num local, o armazenamento externo, que ocorria em quatro instituições e de maneira precária, entre outros. Também, havia conformidades como acondicionamento em sacos e recipientes adequados, segregação dos resíduos comuns. De modo geral, as normas federais não eram atendidas e o gerenciamento de RSSS dos estabelecimentos de saúde necessita de adequação na realização de todas as etapas do manejo, para controlar e diminuir os riscos e reduzir a quantidade de resíduos.

Avaliação dos resíduos sólidos gerados no Restaurante Universitário da UNESP de Rio Claro: uma análise do potencial de compostagem

A consequence of population growth is the increased generation of solid waste, which requires environmentally and economically viable suitable disposal sites. The scarcity of such sites makes necessary to adopt non-generation measures, reduction, reuse , recycling and treatment of solid waste before final disposal of waste. This paper presents the quantification and qualification of organic waste generated in each sector of the University Restaurant (UR) , by proposing indicators of waste generation per meal (index of waste) . Then, from the characterization of the waste management practices adopted internally, evaluates the potential deployment of the composting process for organic waste, with signaling for opportunities to improve waste management. The diagnosis of waste generation was made based on data collected during the period of 10 days. The waste were classified into 3 groups (organic, recyclable and waste) in each sector of the restaurant ( pre preparation , kitchen and tray return) . The results reveal that 33 % of the waste generated in the UR currently has the potential to be composted in a suitable place on campus. Every meal served generat approximately 124g of waste, of which 35g are organic waste of the pre preparation sector, 49g are remnants of food in the tray’s return and 40g are other kinds of waste, including recyclable and non recyclable. You can still get a higher percentage of compostable if the trays pre-wash is not performed with detergent and water. To minimize the generation of waste trays can be replaced by plates and skimmers and ladles can be replaced by smaller ones. The food exposed in the counter but not consumed, can be distributed to students after the restaurant is closed so this material would not be disposed in the garbage

Aplicação da logística reversa como solução para gestão dos resíduos eletrônicos

The present study aimed to analyze how develops the reverse logistics process applied in electrical and electronic products.
