La paca biodigestora como estrategia de tratamiento de residuos orgánicos: una revisión bibliográfica.

Introduction. The Biodigester Bale, also known as Silva Digester Bale, is a technology for the integrated management of organic waste, a process that allows the biological degradation of organic matter into fertilizer, an organic material containing bioavailable nutrients for plants and organisms that benefit soil quality. Objective. To identify and analyze the scientific production and research developed on the Biodigester Bales. Materials and Methods. The Proknow-C method was applied, which consists of selecting a bibliographic portfolio and developing a bibliometric and systemic analysis on it, by means of tracking in databases and institutional repositories. Results. Twelve articles were identified that made up the bibliographic portfolio of research that has been developed on biodigester bales. In the period between 2015 and 2017 the largest number of publications was found, three per year. The most outstanding journal is Producción + Limpia. The different authors have focused their research on analyzing the variation of physicochemical parameters, studying the process of decomposition of organic waste in biodigester bales and evaluating the quality of the final product, its physicochemical, microbiological and nutritional characteristics. Conclusions. Although the scientific information on the method is incipient, which limits its understanding and application. Several authors agree that the Biodigester Bale is a viable method for the treatment and use of organic waste, because it avoids negative impacts on the environment, protects public health and promotes sustainable environmental practices from community participation.
