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.

Brazil faces a complex problem in respect to municipal solid waste, having been in recent years an increase of its generation without the country there be adequate for proper disposal thereof. In many states , the percentage of waste destined improperly , ie , in dumps , landfills, send- outs , among others , is greater than that disposed in landfills , which would be the most correct way to be made. It can be argued that this discrepancy is due to the high cost of implementation and operation of the landfill, and the same need large areas with physical characteristics that suit their operations . When there is a provision in properly constructed landfills , municipal solid waste grounded generate gases with high potential energy through biochemical reactions during the anaerobic decomposition of organic material stored . Such gases can be used for power generation within the landfill or other economic means . To estimate the gas generation will be sufficient for such economic compensation , there are mathematical models that make estimating the amount of gas produced . These models calculate the energy capacity and generation , using parameters obtained based on the characteristics of solid waste , climate of the region where they are grounded and grounding time . Such models have been raised and studied so that it was possible to perform simulations that demonstrate the behavior of biogas generation related to the external conditions of the landfill that interfere with biological reactions within. The results show differences between the values obtained , it shows that the preparation of the models found and used in the simulations were allocated amounts for different parameters that determine this difference in the estimate . Therefore, to rule, the models have difficulty understanding this because there is no clarity in the formulation of the equations , and the definition of variables and parameters would require a detailed study to...

In 2010 Brazil produced about 60.8 million of municipal solid waste, an amount 6.8% higher than in 2009 and six times the rate of urban population growth recorded in the same period. According to a study by the Brazilian Association of Companies of Special Wasteand Public Cleansing (Abrelpe), the average waste generated per person in the same period the country was 378 Kilograms, an amount 5.3% higher to 2009 (359 Kg). The total reached 60.8 milion tons of waste, 6.5 million tons were collected and not end up inrivers, streams and vacant lots. Of this total production, 42.4% or 22.9 million Tons, did not receive proper destination and destiny had dumps and landfills. The data show that the country is in upward trend in waste generation, but did not advance the appropriate destination at the same pace. The waste thus throw open cause public helth problems, such as proliferation of disease vectors (flies, mosquitoes, cockroaches, rats, and others). Generation of odors and especially the pollution of soil, surface water and groundwater through slurry ( liquid black, smelly and high pollution potential produced by the decomposition of organic matter contained in waste), affecting the water. This Study shows the popper closure of the areas, wich long has been degrading our natural resources, not to cause damage to nature and therefore society

This research was mainly focused on public policy analysis of solid waste, and the National Policy and State Solid Waste, as well as determining the performance of the Blue Green Municipality strategic project in relation to the management of municipal solid waste in Regente Feijó, São Paulo. The objective of this research was to analysis of the consequences of the deployment project of selective collection and integration of recyclable material collectors in an association of collectors, called the Association of Recyclable Material Collectors Rock, held in the city from the year 2008, with effective implementation in 2010. We analyzed the actions of the municipal government since the implementation of selective collection, to the development of the Association. The methodology used was literature concerning the issue; routine field surveys to monitor the activities in the landfill and association of collectors, collecting data from questionnaires appropriate to the research topic. We sought to examine old and new forms of urban solid waste management, the evolution of the historical process of this issue in the city and its social and environmental impacts, and the collectors the main social actors in this process. The complexity that addresses this issue was dealt with in this dynamic study, analyzing all parts involved

With the constant increase in the municipal solid waste (MSW) generation, mainly due to the high consumption patterns, it becomes difficult to manage correctly the solid waste and thus minimize their impact on the environment. One of the most problems of the large amount of waste generated is the liquid originated from physical, chemical and biological decomposition process of organic wastes, with dark color and bad smell, called leachate: it can reach the soil, polluting the groundwater and the surface water. Therefore, this study aimed to investigate the process of coagulation/flocculation/sedimentation applied in the treatment of the leachate generated in the not controlled landfill of Presidente Prudente, Sao Paulo...

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.

The issue of environmental impacts to human health and the generation and disposal of solid waste has led to a change of paradigms for your face, highlighting the need for sustainable management of municipal solid waste (MSW). In this context, the expansion of landfills in Brazil in recent decades makes it necessary to sustainable management of waste generated by this type of enterprise, since its implementation. The aim of this study was to perform a diagnosis of the generation of waste in a landfill, in the expansion phase, and the alternatives adopted for its management. The qualitative diagnosis was made from observations on site and the wastes were classified and quantified from August 2011 to January 2012. In the diagnosis was considered the reduction, reuse and recycle, in that order. The results of this study showed that the residue of the greatest generation was PEAD geomembranes used in the waterproofing of the landfill, reaching 7 t, followed by PVC pipes, which reached 850 kg, both destined for recycling. The largest volume of wastewater generated corresponded to the leachate, reaching 11,500 m3 , which were sent for treatment

The theme of solid waste is in high evidence today, a fact noted by the recent implementation of the European directive, and in Brazil, by the National Solid Waste Policy. Understanding the impact of this policy on the national scientific production is essential to plan new directions and research trends. Through a bibliometric and scientometric studied, this research analyzed the national and global context of the last 20 years and found areas in which research progressed, as municipal solid waste, and essentials gaps to develop more the national state-of-the-art, as solid waste of transport. So, the results of this study are a plausible tool to justify for further research on this topic.

The implementation of residue selective collection has brought to the city of Sao Manuel an incalculable benefit. It brought a better life for a group of adults and children that lives in a humanitarian condition of extreme poverty. These people live in an open-air dump, disputing the remains found in fifteen tons of garbage that are deposited at the site almost every day.The objective of this paper is to present thecollectors annual income profile and the volume of solid waste collected.To present these factors, the total and fractionated amount according to their material items, collected since the creation of the Association in February 2003 until December 2008, were considered., In addition,the social gains were enumerated. These factors were developed from a theoretical base for municipal solid waste involving environmental, social, and financial concepts. Based on these results it was found that the ACAPEL income value was above the average of other income indicators of the population analyzed, besides the social value enhance that the creation of the Association brought to the people who work there.

Nowadays, natural gas is viewed as the solution to the problem of energy supply for Latin America, Europe and North America for the next few decades; Brazil is increasingly becoming dependent upon the Bolivian natural-gas supply - many industries and some entrepreneurs are deciding to construct industrial cogeneration systems and new thermal power-stations burning natural gas because of its low environmental impact and attractive price. However, natural gas is a finite resource: this will cause, in the future, an increase of its unit price. This paper details questions involved in the energy generation and presents solid-waste burning as a possible alternative fuel for the future, especially in the context of cogeneration practice in which the thermal and electric energy are used primarily for the industries located in an industrial district. Two cogeneration schemes are proposed for the burning of municipal solid wastes, associated or not with natural gas, and their technical and economic feasibilities are examined.
