Globally, municipal organic waste is creating a bigger
environmental problem. By turning garbage into nutrient-rich compost,
vermicomposting provides a sustainable alternative. The selection of earthworm
species for efficient large-scale vermicomposting of municipal organic waste is
optimised in this study. Vermicompost quality, reproduction rates, waste
reduction efficiency, and adaptability to different waste kinds were assessed
using a combination of case studies, experimental trials, and literature reviews.
Four earthworm species were tested: Perionyx excavatus,
Eudrilus eugeniae, Eisenia fetida, and Eisenia andrei. Eisenia fetida and
Eisenia andrei had higher reproduction rates (3.7 and 3.5 cocoons/adult/week,
whereas Eudrilus eugeniae and Perionyx excavatus attained the highest waste
reduction rates (68.0% and 65.6%) and biomass gains. All species had comparable
levels of vermicompost nutrients (N, P, and K), with E. eugeniae and P.
excavatus having somewhat higher levels. Case studies from various geographical
areas demonstrated that climate, waste composition, and operational size all
have a significant impact on species performance.
A decision-making approach is suggested to help Urban Local
Bodies identify the most effective earthworm species for their particular
conditions. The results demonstrate the critical role of species selection in
maximising vermicomposting effectiveness and ensuring sustainable municipal
waste management.
