Abstract
The valorization of agro-industrial wastes (AW) by means of waste-to-energy strategies through anaerobic digestion (AD) is a reality in developed countries. In Latin America, there are different problems in the management of AW from intensive livestock farming. This study aims to provide a pseudo-radiography of AD management systems with a focus on anaerobic lagoons in Latin America (LATAM). Using data science, quantitative and qualitative data from 1003 scientific papers were synthesized and analyzed to form a database; which allowed evaluation of the congruence of the scientific research with the real problems of LATAM management. The results showed that anaerobic lagoons in the region are the main AW management systems (mainly bovine and swine manure) and that scientific research in this sector does not address the related problems. 38 types of inhibition phenomena with a total of 5264 mentions were addressed in the database. Nitrogen-related AR inhibition phenomena represented 21% of the incidences in this study, besides being the most significant phenomenon in anaerobic lagoons in LATAM
