Evaluación de la eficiencia del proceso de compostaje a partir de diferentes tamaños de residuos orgánicos, como alternativa de manejo de desechos de la actividad florícola, Cayambe, 2022

Abstract

Composting is a technique for the treatment of organic waste produced as a result of anthropogenic activities. In Ecuador, 98% of the organic waste produced in urban areas is deposited in landfills. This represents problems such as a reduction in the useful life of the landfill and the generation of leachate whose treatment requires a lot of investment. On the other hand, in agricultural production areas, organic waste is recycled by decomposing it in situ, on the ground or by piling the waste in a compost bin; however, the latter is done in an anti-technical way due to that there is no adequate management or treatment of the waste that enhances its use in composting, it is for this reason that in the present investigation the influence of the size of the organic waste used for the composting process on the physical properties was evaluated. and chemicals of the final product. The materials used in the investigation were; bovine manure, black earth or moorland, and rose stems cut into different sizes. According to the results obtained, the size of the materials to be composted directly influenced the quality of the compost obtained, thus, with smaller sizes of rose stems, a compost of higher nutritional quality was obtained, unlike the stems with higher size whose nutritional content was significantly lower. Consequently, it can be affirmed that starting the composting process with a carbon-nitrogen ratio of 30, in terms of the time variable, the smaller the organic matter particles, the longer the composting time. Finally, the size of the residue was not an interaction factor within the composting, the material obtained a great significance of interaction with the variables, since it influenced the final quality of the compost.
