Item Establecimiento de las condiciones de compostaje utilizando microorganismos eficientes y desechos orgánicos producidos en restaurantes de la Universidad Santiago de Cali(Universidad Santiago de Cali, 2021) Cosme Perlaza, Jefrid Leandro; Molina Rada, Ananda Esther; Quijano, Silvia Andrea; Falco, AuraThe Santiago de Cali University produces a wide variety of wastes that are mostly organic and, currently, are not used properly. Composting emerges as an alternative that transforms solid waste into organic fertilizer for the soil, however, this process usually takes several months. The use of efficient microorganisms is an option to optimize the time of the composting process. The objective of this work was to establish the conditions for composting organic waste produced in restaurants of the Universidad Santiago de Cali, using efficient microorganisms and the Autonomous Composting System SAC-2250. Initially, the standardization of the conventional composting process was carried out, evaluating four treatments with different amounts and combinations of substrate. The results indicate that treatment 1 (3 parts of organic matter per 1 of sawdust) had the best behavior compared to that reported in the literature (the duration of the process is 45 days). Subsequently, three efficient microorganisms identified as Klebsiella oxytoca, Sphingomonas paucimobilis and Pantoea spp were isolated and inoculated in treatment 1. The results indicate that the inoculum reduced the composting process in 20 days, when compared with the control cell. The proper management of the organic waste will significantly reduce the accumulation of them, decreasing the environmental impact and therefore the rate of cleanliness in the institution, in addition it faces an aesthetic and landscape component in the community Santiaguina.
