Experimental and technoeconomic analysis reveals optimized feedstock enhances methane production in rural settings.

Methane yield increased to 48% through co-digestion of food waste, cow dung, and green waste, stabilizing the digestion process.
Primary metric highlights an NPV of AUD 2834 and IRR of 13.5%, indicating strong economic viability for a 500 L biodigester.
Observational analysis across small-scale anaerobic digestion revealed the best feedstock combinations for biogas production.
This research underscores the potential of integrating economic assessments to promote biogas systems in rural areas.

Mahmudul et al. (2025) studied this question.
