| Abstract |
The present study evaluates the design and techno-economic potential of circular economy-based biogas plants for Indian cattle shelters for combined heat and power (CHP) and compressed biomethane gas (CBG) applications. The biodigester is designed based on available dung, and the economic performance is evaluated using the net present value (NPV) method. For small shelters (500 cattle), the framework showed an NPV of US $0.089 million for CHP and US $0.07 million for CBG. For large shelters (5000 cattle), the framework showed an NPV of US $2.78 million for CHP and US $2.80 million for CBG. Availability of dung, discount rate, and the market price of solid fertilizers significantly influence the NPV of the biogas plant. The GHG emission analysis shows that CHP application has lower emissions than CBG application, particularly for bigger plant. It is recommended to build biogas plants inside or near cattle shelters with a minimum dung availability of 2.25 t/day for both applications. |
