Abstract
Four types of wastes were collected from different stages of leather processing namely,
LDB-BT, LDB-AT, PW-BT and CTW-ACR and mixed with equal amounts of vegetable wastes
and vermicomposted using local species of earthworms and then analyzed. The results
show an increase in pH, EC and decrease in COD, TDS, phosphorus, potassium, sodium,
calcium, and magnesium in the vermicompost.
