The issue of waste, historically, has been getting worse as a result of the world´s population increase and in order to meet their needs the consumption of natural resources and the generation has been constantly increasing, especially in large urban centers. The people involved in the collection of recyclable solid waste, called from now on as collectors, are responsible for about 90% of the waste sent to recycling industry in Brazil. Apart from having a role in the economy, the collectors have specific knowledge and skills necessary to identify, collect, sort and sell these wastes. This study aims to examine the possibilities and limits of COOPERVIVA – Cooperativa de Trabalho dos Catadores de Material Reaproveitável de Rio Claro - as an instrument of the municipal solid waste management system, and its experience as a recyclable waste collectors cooperative. The methodological procedures of this study rely on the literature research on the experiences of cooperative and the management of municipal solid waste. In addition to this review of the literature, fortnightly visits to the cooperative were held in order to experience their daily activities, and testimonies of the cooperative members were collected as well as documents and reports produced by COOPERVIVA. The results of this analysis are considerations of the limitations of the cooperative and recommendations aimed at maximizing their potential as a tool of the domestic solid waste management system of and as a recyclable waste collectors cooperative. Among other things it can be concluded that the urban selective collection of waste challenges the community to the reinvention of life and the relationships each individual with the planet.

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...

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).

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.

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

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.

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...

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
