The literature review indicates that the design of environmentally friendly biogas plants is associated with solving scaling-up problems that account for biogas production, purification, and upgrading processes. Many existing models of membrane gas separation lack a unified character and require adaptation to specific membrane types and gas mixture compositions. In this regard, the development of a generalized model structure suitable for describing separation processes while considering purification features remains a relevant task. From the standpoint of environmental and energy efficiency, there is a need to develop effective solutions aimed at improving productivity and system sustainability. The paper is devoted to a systems analysis of biogas plant design, with particular emphasis on scaling-up issues and their influence on the energy and environmental performance of the plant. The main levels of problems arising in the design of biogas plants are formulated, taking into account the combined impact of biogas production and purification units on the overall efficiency and environmental performance of the technological process. Key factors determining the efficiency of biogas production and purification are identified, and the features of their manifestation during the transition to largescale systems are analyzed. Systems analysis is used to determine approaches for increasing separation efficiency, improving final product quality, and developing biogas plants with higher specific productivity under a moderate increase in energy consumption, contributing to the reduction of methane emissions. The feasibility of applying two-stage purification schemes in membrane systems and column apparatuses is demonstrated in terms of energy efficiency and environmental safety. It is concluded that the scaling-up problem requires a comprehensive approach, including mathematical modeling and process control optimization, particularly under significant variability in feedstock composition and properties, to ensure the economic, energy, and environmental efficiency of biogas plants.
