Methodological aspects for the management of local projects that generate and use biogas for energy purposes. Universidad y Sociedad [online]. 2022, vol.14, n.1, pp. 474-483.  Epub 10-Fev-2022.

Biogas technologies have reached a wide development, but the methodological conduction associated with pre-investment studies in local projects that use this energetic option has not been effective. The objective of the present work is to establish a methodological procedure that facilitates the conduction of business, technical and investment decisions in local projects, new or of industrial reconversion and with generation and use of biogas. The methodology has its antecedents in technological management, complex process analysis and technological adoption (assimilation) and has a novel and heuristic approach. An integrated diagnosis is carried out that conceptualizes the initial scenario and considers development strategies and the technical and economic analysis of alternatives. The size of the projects is defined by their energy demands and availability of attractive waste for anaerobic digestion. The procedure facilitates the definition of energy demand, type and availability of substrates, pretreatments, design and scale-up, cogeneration, and feasibility and sensitivity study. The proposal was successfully applied to a case study for the production of cassava flour, using biogas generated from swine waste as an energy option for drying.
