This undergraduate thesis addresses the challenges of collective composting and its effects on climate change. Garbage collection is costly to public coffers, so composting is a viable alternative. In this sense, the National Solid Waste Policy raised the discussion, not only on the need to send to the landfill only what is not possible to apply any type of treatment, but which alternatives for proper disposal of Organic Solid Waste. From this perspective, composting presents itself as an instrument of the National Environmental Policy as an alternative for adequate destination of the organic solid waste. So, is a discussion relevant to clarify what the challenges of collective composting and their effects on climate change are? When performed in neighborhoods and large generators of urban solid waste (condominiums, supermarkets, schools), composting increases popular participation and institutional structures in the management process. In addition, composting has the potential to create local jobs, adapting to specific socioeconomic situations. In landfills, when organic materials are buried and compacted, they enter into an anaerobic decomposition, forming various gases, such as methane gas (CH4). These gases must be captured to be treated or destined for energy use, which is not always within reach of governments, since it requires investment in research, technology and political articulation. On the other hand, when the organic solid waste is treated using composting technique, it occurs the minimization of the parcel to be sent to the sanitary landfill by reducing the volume, the amount of leachate, and, consequently, the risks of contamination of the water resources and the emission reduction of greenhouse gases into the atmosphere. The society's need for space and improved solutions in waste management is noticeable. The gain provided by composting is clear. In this way, this research has as general objective to analyze how the collective composting can be a solution for Urban Solid Waste. In addition, it has following specific objectives: to highlight the social relevance of solid waste management, to propose collective composting as a solution for municipal solid waste, to highlight the effects of collective composting on climate change. Therefore, the methodological proposal of this work is classified, as regards the objectives, as exploratory and descriptive and, as far as the methodology, as bibliographical and documentary.
