Abstract

Leaf litter occupies a major fraction of decentralised point source organic fraction of the municipal solid waste. Leaves can be either succulent easily degradable or recalcitrant. Literature has shown studies with leaves or leafy biomass feedstock. It is, therefore, necessary to study the different types of leaves to understand their extent and rate of decomposition (biogas production). This study focuses on five leafy biomass which has shorter growth period as a source of leaf litter. Two predominant patterns can be seen, (1) with gas production ranging between 200 and 250 ml/gVS and (2) with low gas production and lower methane content (90–120 ml/gVS). Gompertz model shows cases with higher gas production rates with longer lag phases and case with no lag phase and low specific gas production rates. So, a clear understanding that delves into structural components of leafy biomass is needed.
