Low Construction Costs: Covered lagoon anaerobic digester often has lower capital investment cost. The earthwork excavation and geomembrane lining of digester are typically less expensive.
Ease of Construction: Covered lagoon digester is relatively straightforward to construct. They often involve excavating a depression in the ground and lining it with impermeable materials.
Natural Process: The anaerobic digestion in lagoons relies on natural microbial activity requiring minimal mechanical intervention. It’s a relatively simple and low maintenance approach.

Land Area: Covered lagoon requires larger footprint, making them more suitable for locations with ample space.
Pit Soil Area: May have high permeability, can allow gas and liquids to escape, reducing the efficiency of the digester and potentially causing environmental contamination.

Space Efficiency: CSTRs are more compact and can be installed in areas with limited space.
Controlled Environment: CSTRs provide better control over the anaerobic digestion process, allowing for optimized gas production and faster decomposition.
Flexible Design: CSTRs can be easily scaled up to accommodate changes in feedstock availability or processing requirements. Retrofit and upgrading of existing plant are greatly facilitated.
Co-Digestion: CSTRs accept multiple co- digestion feedstocks, typically capable to handle a solid content up to 15%.

Higher Construction & Operational Costs: CSTRs generally have higher initial costs due to the need for more intricate construction and materials.
Maintenance: CSTRs may require more maintenance and monitoring to ensure proper functioning.
