Diseño de una planta de compostaje a partir de residuos orgánicos generados en el mercado municipal Santos Leopoldo Cabezas Villalba del cantón Guano

Abstract

The aim of the current technical work is to design of a composting plant to treat organic waste generated in Santos Leopoldo Cabezas Villalba municipal market located in Guano county and mixed with banana and pruning waste. With this waste, 2 compost piles were built: Pile1: 100 Kg of pruning waste and 146 Kg of market waste; Pile 2: 100 Kg of pruning waste, 146 Kg of market waste and 568 Kg of banana, some mountain microorganisms were added in each treatment. In this process, temperature, humidity, pH, electrical conductivity, organic matter, and aeration were controlled. The turning process was performed in a manual form and based on the temperature. The sampling was carried out before each turning process. The parameters analyzed with their corresponding results were: pH: Pile1 (7.92) and Pile 2 (7.63), electrical conductivity (dSm-1): Pile1 (3,16) and Pile2 (4,41), Organic Matter: Pile1 (46,8 %) and Pile 2 (42.2%), Germination Index (GI), the highest percentage obtained was (91.05%) in Pile 2 and (70.32%) in pile 1. Based on the results on the quantity and characteristics of the organic waste generated, the plans for a composting plant were designed with the following dimensions: 13.9 m in width by 27.74 m in length, it also has 8 areas for the composting process. It is concluded that the compost obtained can be used to improve soils with poor organic matter and macronutrients since, established values accepted by the international regulations were obtained. As the composting plant is one of the alternatives to treat organic waste, it is recommended for the municipality of Guano to build an organic waste composting plant for the municipal market of Guano county in order to promote and contribute to the environment care.
