Evaluación del comportamiento de los microorganismos eficientes para acelerar la transformación de los desechos sólidos orgánicos originados en el Mercado San Alfonso-Riobamba.

Abstract

The objective was to know the behavior of the Efficient Microorganisms (EM) in accelerating the processes of degradation of organic matter in the composting process. The organic waste was produced by pulses, vegetables and fruit commercial stands of Municipal Market "San Alfonso" of Riobamba city where the process of a daily pickup was carried out during a week. A private property was set up for building twelve compost bins or piles of a cubic meter distributed as follows three for control pile, three for Treatment 1, three for Treatment 2, three for Treatment 3. Different dosages of efficient microorganisms were established for the treatments in order to know the catalytic power of the EM; 60 ml for the Treatment 1, 120 ml for the Treatment 2 and, 180 ml for the Treatment 3. Later, temperature measurement was conducted daily (ºC), humidity (%), the hydrogenic potential (pH) to keep appropriate conditions for optimal performance in the oxidation of organic matter. The composting process concluded when the temperature reaches its stabilization phase close to ambient temperature, and the final product assessment was carried out wi¡th1 values of C/N of 17,77 due to the carbon loss because of the oxidative processes and the C02 emission. Thereby, more effective treatments accelerating the processes of degradation of organic matter were Treatment 2 (120 ml of EM) and Treatment 3 (128 ml of EM), the efficient dosage improves the composting time found among the concentrations of the treatments established as efficacious.
