Avaliação estratégica de um plano de gestão de resíduos sólidos com foco nos resíduos orgânicos

One of the greatest problems nowadays is the correct management of solid waste produce in every human activity. On 2010, the “Política Nacional de Resíduos Sólidos” was approved, this law brings directives and instruments to deal with the solid waste issue. The objective of this work is to make a Strategic Assessment on a Solid Waste Management Plan applied to a medium size city. Based on general data about the situation of the solid wastes in Brazil, a first scenario was described. After that, likely scenarios were proposed, taking segregation, treatment and final disposal on account. Finally, those scenarios were compared, mainly in the final volume disposed and costs involved

Avaliação do gerenciamento e disposição final dos resíduos químicos de laboratórios do IGCE, UNESP - Rio Claro/SP

Laboratory of Chemical Waste Management programs are being implemented in various universities of the country and the world, in recognition of the urgent need to change the reality of disregard for the environment, together with objective responsibility of the generator, and especially the awareness of sustainability. Analysis and research laboratories involve a range of waste in developing their studies with intrinsic characteristics related to their form of generation. The amount of waste generated in this segment is negligible compared to industrial activities, but the environmental issue is that these residues do not have a standard technique for treatment due to the potential variation of its composition. This research project, aiming their suitability and continuous improvement, aims to diagnose and analyze the current situation of the management and disposal of chemical waste generated by the laboratories IGCE UNESP, Campus Rio Claro / SP. Universities, through their research, teaching and extension, end up generating potentially hazardous chemicals that may contaminate the environment when they are disposed of improperly, with no concern for the environment and / or public health. Aiming to assist in improvements with respect to this issue, the purpose of this study is to understand the management and disposal of chemical waste from the IGCE, laboratories UNESP - Rio Claro / SP, in order to discuss the situation of such waste, and present proposals to reduce generation of the same and minimizing the environmental impact, thereby increasing the local hygiene through proper disposal. The research instrument used interviews, questionnaires, review of recent literature and observations were made in order to develop proposals for the management and disposal of waste. These proposals based on prevention and corrective control, where the preventive approach aims at lifting techniques and actions to reduce the generating sources and...

Diagnóstico dos resíduos de construção e demolição para elaboração e implantação da gestão integrada dos RCD no município de Guanambi – BA

Taking as starting the environmental, social and economic impact of construction and demolition waste in Brazilian cities were created legal mechanisms for management and administration, seeking to minimize the impacts to the maximum, since the irregular deposition can be characterized as environmental crime. CONAMA Resolution No. 307 of 2002 establishing the mandatory implementation of an Integrated Management System Construction Waste and Demolition, guiding the classification and designation of the waste generating agents, collection agents and transporters, and the areas of culling and disposal of waste. The technical partnership between the Ministry of Cities, the Environment Ministry and the Caixa Econômica Federal, coordinated by Pinto & Gonzales (2005) Management in the work and management of construction waste, proposed a guidance manual to guide the implementation of a System Integrated Management of Construction Waste in Municipalities. The municipality of Guanambi in the state of Bahia, in full economic rise, lacks a waste management of construction and demolition, since there has areas for the disposal of waste being proposed in this paper the diagnosis of waste generation in the municipality as part of the methodology proposed by the work of Pinto & Gonzales (2005).

Considerações gerais sobre os resíduos eletrônicos

As new technologies improve, people’s lives gain in comfort and accessibility. However, along with these technologies comes a growth in “soon to fall into disuse” product consume, either because they have reached the end of their life cycle, or because they were substituted by newer and more advanced models. These electronic wastes are still with no certain destination, and could be donated to welfare companies, but the majority is thrown in wide open dumping grounds or landfills, where they can contaminate water and soil with their toxic components. This work seeks to evaluate the e-waste concept, their impacts in the environment and human life, as well as the current national and international e-waste management and destination, finally reflecting on international decisions that would be appropriate for the Brazilian system.

Gestão de resíduos sólidos domiciliares orgânicos: práticas e técnicas para a destinação final na cidade de Rio Claro - SP

The present work is the analysis of the practices and techniques currently used in the final allocation given to organic household solid waste in the city of Rio Claro - SP. As the major part of Rio Claro’s household solid waste is formed by the organic fraction, as well as in the rest of the country, this research proposes a study on what is done with that portion of the waste, its treatment and where finally destined, based on the National Solid Waste Politic, recently approved in 2010. With the use of this organic part, for example: as animal feed supplement or compost embodiment for the purpose of producing organic fertilizer, enables the decrease of the percentage of the total destined to dumps and landfills. This total percentage has already been reduced after the popularization of the beneficial recycling programs in Brazil, which are still growing. As cities and the purchasing power of its individuals grow, there is also a consequent growth of waste production by society. The household whether domestic solid waste are lower than Industrial Solid ( RSI ) waste for the production in million tons ( Mton ) quantities , however, those residues are more visible on a daily basis - in cities and periphery as well, due to the inadequate management, - and also offer , as well as industrial and agricultural wastes , several types of harmful effects to the population when managed incorrectly. Therefore, the research aims to assist in the study of Solid Waste Management (MSW) for efficient Urban and Environmental Planning in a midsize city. Thus, this project aims to analyze in the city of Rio Claro, how the allocation of these materials is done and whether these practices denote effective improvement regarding the proper management of waste, in the same way that the recycling chain would allow this effect

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

Plano de gerenciamento sustentável dos resíduos de construção civil. O caso de Rio Claro (SP)

The current problematic of the construction and demolition (C&D) waste faced for the Brazilian cities, is one of the main degradation factors of the environment, over all about the promise of the urban ambient quality. This scenery must mainly to the unsustainable management adopted by the great majority of the Brazilian cities. Therefore, this work aims at to offer subsidies for medium cities, having as study object the city of Rio Claro-SP, (Brazil), in the elaboration of plans and integrated programs of sustainable management of the construction and demolition waste, in accordance with CONAMA Resolution nº 307/2002, that’s set up a sustainable management system of C&D waste. In this direction, the diagnosis of the management was elaborated for the city of Rio Claro, (generation, collects, transport and disposal) and the public administration of the construction and demolition waste, as well as of the study of the related aspects with C&D waste recycling plant. Later, was suggested a plan of improvements for the public manager of C&D waste: areas of temporary disposal to facility the appropriating destination, appropriated areas of final disposal, incentives to the recycling of C&D waste, new legislations, education and orientation programs and adequacy the agents of C&D waste management (generating, transporting, addressee and public manager), directing for an environmental, economic and social sustainability.

A política nacional de resíduos sólidos e o plano diretor municipal de Rio Claro/SP: o uso como instrumento para a gestão urbano-ambiental municipal

Due to the large economic development associated with the growing consumerist lifestyle of our capitalist society, the problem of uncontrolled solid waste generation worsens, which one is considered to be one of the main responsible factors for environmental degradation. As a case study and in order to solve the problem of large generation of municipal solid waste, this work aims to study the “plano diretor” of Rio Claro city, São Paulo. The “plano diretor” is a municipal law that provides guidelines for the administration of the city, which include guidelines for the management of solid waste generated in the city. The guidelines required in order to write the “plano diretor” are provided by the national law “estatuto da cidade”, providing information for the planning and development of the cities, as well as the management of the urban environment. However, only the “estatuto da cidade” does not provide enough instructions for creating management plans in order to solve the many problems from the urban environment. Thus, studies have been done about urban and environmental management, to understand how municipal management plans should be structured. As a form of seeking information that can complement the “plano diretor” to the creation of policies for managing solid waste of the city, the “Política Nacional de Resíduos Sólidos”(PNRS) emerges in 2010 as a document which provides principles, objectives and guidelines to create plans for Solid Waste Management at the national, state, regional and municipal levels. Therefore, it was possible to make a joint analysis of the “plano diretor” of Rio Claro with the PNRS to identify what is already done within the municipality about the solid waste management, and identify which aspects are most significant in the municipal solid waste management that the national policy provides. Yet studies have been done on the current municipal solid waste management...

Aplicações práticas de proteção radiológica nas áreas de medicina nuclear e radiodiagnóstico em instalações hospitalares

After the discovery of ionizing radiation, its applications in various fields of science began to take significant proportions. In the case of medicine, there are the application areas in radiotherapy, diagnostic radiology and nuclear medicine. It was then necessary to create the field of radiological protection to establish the conditions necessary for the safe use of such ionizing radiation. Apply knowledge obtained during the graduation stage and in the practice of radiological protection in the areas of nuclear medicine and diagnostic radiology. In the area of nuclear medicine, tests were made in the Geiger-Muller counters (GM) and the dose calibrator (curiometer), the monitoring tests of radiation, waste management, clean of the Therapeutic room and testing the quality control of gamma-chambers. In the area of radiology, were performed tests of quality control equipment for conventional X-ray equipment and x-ray fluoroscopy, all following the rules of the National Health Surveillance Agency (ANVISA), and reporting of tests. The routine developed in the fields of nuclear medicine in hospitals has proved very useful, since the quality control of GM counters contribute to the values of possible contamination are more reliable. The control of dose calibrator enables the patient not to receive different doses of the recommended amounts, which prevents the repetition of tests and unnecessary exposure to radiation. The management of waste following the rules and laws established and required for its management. Tests for quality control of gamma chambers help to evaluate its medical performance through image. In part of diagnostic radiology, tests for quality control are performed in order to verify that the equipment is acceptable for usage or if repairs are needed. The knowledge acquired at the internship consolidated the learning of graduation course

The objective of this study was to analyze the performance of solid waste management in the municipality of Tibagi, Paraná, a city with approximately 20000 inhabitants, which implemented the selective collection program called Recycle Tibagi. The analysis was based on descriptive statistical techniques, considering the three types of waste (tailings, organic and recyclable), and per capita generation of garbage upward trend in the coming years, based on the method of Winter (Triple Exponential Damping), using data recorded by the Department of the Environment and the Association of Recyclable Materials from Tibagi - ACAMARTI. Efficient selective collection from a structured environmental education program with constant training conducted with the scavengers, possible to obtain important data in sorting and marketing of recyclable materials, saving raw materials, water and energy, as well as relevant indicators social inclusion and employment generation and income. The project involves several areas of municipal management and arouses curiosity and interest in several areas: social, financial, environmental and administrative. It's a way to encourage new projects and public bodies, highlighting the importance of recycling and proper disposal of solid waste.

Recycling scrap automotive heat shield insulation material

Automotive heat shields are usually composed of two metal sheets enclosing an insulating material with a paper-like texture that contains refractory ceramic particles. This article discusses the results achieved by recycling the scrap automotive insulation that is discarded in landfills, using the same concept as paper recycling. For comparison with the original product, tests of thickness, bulk density, weight loss on ignition, tensile strength, compressibility, and recovery were performed on recycled materials produced in a so-called "manual" process (involving little automation and performed in adapted facilities) without pressing, and pressed once, twice, and four times. Materials recycled in a so-called "industrial" process (in a paper recycling plant) without pressing, and pressed once were also tested. The recycled materials can be considered approved with respect to the main requirement, thermal insulation, since they dissipated the under-hood temperature by more than 300 A degrees C (like the original product). Like the heat insulation tests, the thermogravimetric analysis suggested that the recycled materials showed higher stability than the original product. Thermogravimetric, microscopy, and energy dispersive spectroscopy analyses indicated that the structural and compositional characteristics of the original product were preserved after recycling.
