Abstract
- In India, many biogas plants process cattle dung (CD). At the same time, an excessive amount of litter of leaves is swept and burnt. The paper investigates small-scale integration of leaf litter of neem (LLN) to the operational CD-based biogas plant under mesophilic conditions. The introduction of LLN at the volatile solid ratio of 1:4 (LLN:CD) respectively increased daily biogas production, specific methane yield, and the resultant electrical energy by 13.11, 15.26, and 15.02% and reduced the proportion of CO<subscript>2</subscript> by 5.85%. However, because of the energy required to pulverize the LLN in CD-LLN–based, the net percentage increase of the electrical energy dropped to 13.59%. CD-LLN–based reactor also produced 56.34% higher electrical energy per organic substrate added and performed well by 15.0% in terms of CO<subscript>2</subscript> emission compared to CD-based. Digester performance was seriously unaffected during the transition stage. The study highlights another way of managing LLN and shifting anaerobic reactors from one feedstock to another.
