“Obtención De Compost A Partir De Residuos Sólidos Orgánicos Generados En El Mercado Mayorista Del Cantón Riobamba”

Abstract

The process of obtaining compost was developed at the Agroambiental Ricpamba theme park administrated by the Autonomous Municipal Government of Riobamba (GADM, where an organic fertilizer was obtained from solid waste generated in the wholesale market of the city of Riobamba in order to be use in parks, gardens, green spaces and in agriculture, for which, a stack of 1,0 tonne was armed formed with fixed proportions in relation to weight / weight from three organic components of plant type: Organic solid waste wholesale market (600 kg), tree pruning waste of the Polytechnic School of Chimborazo (300 kg), and prunings waste of ornamental palm (Phoenix canariensis) from the city of Riobamba (100 kg) To achieve adequate carbon nitrogen ratio (C/N). The compost was performed using an open stack system and manual turning; during the process a daily control of temperature and humidity was performed, besides that during each dump material samples were taken for analysis of the most important parameters, thus controlling the process. The temperature evolution of the stack in the mesophilic phase reached 45 °C and thermophilic phase temperature was above 60 °C, which was controlled with manual turns. Once the process was finished the quality of the compost was proved by the physical-chemical analysis, chemical-biological to determine its quality. Additionally the solid waste generated in the Public Municipal Market of “San Pedro de Riobamba” (EP-EMMPA) were classified and quantified on a daily basis. The solid waste were classified in 6 groups: organic, plastics, paper, cardboard, wood and others, being organic waste the ones found in a greater amount, in an average of 95.59%. The obtained product has the right physical-chemical, chemical-biological property to be used as an organic fertilizer or soil improver by providing essential nutrients, macro and micro elements required by plants.
