Compostagem domiciliar: estudo de caso em uma residência no município de Laranjal do Jari, Amapá

Abstract

Over the years, the changes that have occurred in society's consumption patterns have become evident, bringing with them serious questions regarding the generation of waste and its final destination. It is observed that the majority of solid waste produced by the population still does not have an adequate destination, often being dumped directly into the environment, causing environmental damage. In this panorama, organic waste emerges as a recurring concern, especially with regard to its disposal, considering that its decomposition has the possibility of contaminating soil and water resources. It is noted that there are strategies that allow the reduction of organic waste levels, such as composting. Thus, the objective of this research was to investigate the efficiency of home composting to reduce organic waste in a home in the municipality of Laranjal do Jari, Amapá. The research methodology adopted was a case study in a residence in the municipality of Laranjal do Jari, where a home composting system in plastic buckets was implemented. During the experiment, organic waste produced at the residence was collected from June to August 2023. 18,503 kilos of organic waste were produced, with an approximate average of 6,100 kilos per month. At the end of the experiment, the organic waste generated was reduced by up to 92%, with a view to producing 1,456 kilos of organic fertilizer and 4,650 liters of biofertilizers.
