Situational analysis of the Teresina sanitary landfill and assessment of the efficiency of the compostage process

Abstract

Landfills are examples of spaces with operational techniques aimed at protecting the environment from potential damage. These landfills receive a large amount of waste daily, including organic waste, which can be transformed into compost for agriculture through composting. The central question is: Is there viability for the composting process under the geospatial conditions of the Teresina landfill? The main objective is to analyze spatial viability for implementing a Composting Unit in the landfill to utilize the deposited organic waste. The research is based on a methodological approach that incorporates literature review, document analysis, and field data collection as essential procedures. These methods were employed to provide a comprehensive and in-depth understanding of the topic under analysis. During the visit to the landfill, it was possible to understand its operation, including the controlled landfill in operation and the sanitary landfill under construction. Additionally, the entry of waste and organic residues into the landfill was observed. Although there is space for the construction of a Composting Unit, as of the visit date, nothing had been implemented. It is concluded that the landfill has spatial viability for a Composting Unit, along with raw material for organic compost production. Therefore, a composting unit in the landfill will optimize space. Up to the time of the visit, the Teresina landfill showed inefficiency in treating organic waste.
