The anaerobic biodigester has become an effective solution for the sustainable management of organic waste, especially in the pig industry. Objective: The objective of the study is to evaluate an anaerobic biodigester for the production of biogas and biofertilizer from pig waste in the Province of Santa Elena. Materials and Methods: It is a quantitative study, descriptive cross-sectional type, experimental design. The sample consisted of 65 pigs. The direct observation technique was used through records of the entire process in the biodigester. Results: The implementation of a biodigester in the Santa Marianita pig farm proved to be an effective solution to manage organic waste and promote sustainability. With a total volume of 39 m³, the biodigester processed 219.52 kg of manure and 655.1 liters of wastewater daily. After 33 days of operation, promising results were obtained: 9.57 m³ of biogas, a renewable energy resource that can be used for cooking or generating electricity, and 24.09 m³ of biofertilizer, a nutrient-rich product that can improve soil quality and reduce dependence on chemical fertilizers, were produced. It is concluded that the implementation of the biomanager significantly reduced bad odors and prevented soil and water contamination, demonstrating the potential of this technology to mitigate the environmental impacts associated with pig production. These results confirm that biodigesters can be a valuable tool to promote sustainable agriculture and efficient management of organic waste.
