This study addresses physical characteristics of gravimetry, presenting as a context the characteristic condition of waste for better use of recyclable waste for recycling, with organic solid waste digestible through technologies that can be better used. The main objective of the study is to identify, through gravimetric data, the possible technical relevance for the waste generated by large generators in the metropolitan region of Belém, for a better use of waste. In this way, it will have a contribution to increase the useful life of the sanitary landfill located in the area under study. The importance of gravimetric data for the survival of sanitary landfills is because it is an important tool in terms of the Solid Waste Management Plan, allowing the analysis of quantitative and qualitative data from the gravimetry of large generators, allowing to present the difficulties and possibilities to implement a disposal system with better use of waste and to identify which are the major generators of solid waste in the current situation in the Metropolitan Region of Belém. The development of this
research was divided by primary and secondary data; data analysis for the purpose of results regarding the study of gravimetry, descriptive statistics were analyzed; gravimetric analysis by graph; analysis of the gravimetric composition of RS through boxplot graphs; KruskallWallis test – GG; and literary study for foundation. The results of the survey show that the amount of digestible organic matter, as the highest power in the waste, is around 80.9%, confirming that the organic waste from large generators is completely avoidable for disposal in landfills, and should be directed to treatments with technology sustainable production of energy or compounds, leading to relevant reflections on waste to propose composting techniques, generating waste inputs for agriculture.
