Biodigesters in microscale in the context of contemporary social practices
The complex emergencies of the 21st century demand new formats and solutions, therefore based on an alternative Technoscience, this study proposes the production and operation of a model of an anaerobic digester for energy and nutrient recovery from organic waste in a domestic scale. This work presents an experimental research with review interdisciplinary theoretical approach on the relationship between biodigesters and interested people. The methodology used is coherent with Citizen Science and Solidary Technoscience, the importance of Action Research as a method is recognized, and a protocol is sought that allows the continued participation of stakeholders. Using proprietary research methodology with biodigesters, the Biochemical Methane Potential of samples of Food Waste from a restaurant in São Vicente/ SP were determined experimentally, demonstrating good energy production potential. With the construction of two biodigesters in a format consistent with the proposed methodology and using an alternative analysis methodology to that used in professional laboratories, however allowing the comparison of production and substrates used, a digital community of the boitatá biodigester is established, concluding the possibility and feasibility of constituting communities of biodigesters of food scraps in an urban environment, despite some limitations.
