Evaluation of biofertilizers obtained from animal waste from the Guaranda Municipal Farm

Abstract

The objective of this investigation was to carry out an evaluation, in light of the collection of recent scientific information, of the state of the art on the use of animal waste as inputs for obtaining biofertilizers in the Municipal Farm of Guaranda, Bolívar province. The methodology was framed in documentary research. For the information search, the Google Scholar database and indexed journals of literature published between 2018 and 2022 were selected as search engines, however, documents from years prior to the aforementioned date were also included because they were considered relevant for this study. work, likewise, the digital repositories of national and international universities and pages of organizations such as FAO, PNUM, IICA and OECD were investigated. The search was carried out using keywords such as "biofertilizers" "municipal slaughterhouses" organic waste" "Municipal slaughterhouse of Guaranda". The population was made up of 33 documents grouped into articles/theses and others. Subsequently, the sample was selected through a non-probabilistic sampling of an intentional type, being made up of 07 sources. The information collected was systematized through content analysis. Result: The most important impact identified from the operation of the Slaughterhouse was the generation of wastewater, associated with high contaminant loads for the environment. Conclusions: The recycling of organic waste, for the production of biofertilizers, is viable for the solution to the environmental problems generated by the slaughter of animals in municipal slaughterhouses, specifically, in the Municipal slaughterhouse of Guaranda, Bolívar province.
