Hi Natalia,

I think, designing a biogas plant requires careful modeling to ensure the system performs efficiently and sustainably under real-world conditions. The most important aspects include understanding feedstock variability—how different materials affect gas production and retention time—and selecting the right digester size and type based on input volume and temperature requirements. Modeling also helps estimate energy output (biogas volume and methane content), simulate heat and mixing needs, and plan for digestate handling. Integrating the plant with nearby farms, industries, or energy networks adds value but requires system-level simulations. Finally, economic modeling is essential to evaluate costs and revenues, ensuring the project is both technically sound and financially viable.
