Abstract
The aim of this work was to study the effect of the traditional thermophillic composting
thatcommonly adopted for treatment of organic wastes or for production of organic/natural
fertilizersthat is introduced to a related technique, called vermicomposting (using earthworms
to breakdown the organic wastes). These two techniques have their inherent advantages and
disadvantages. The integrated approach suggested in this study borrows pertinent attributes
from each of these two processes and combines them to enhance the overall process and
improve the products qualities. Two approaches investigated in this study are: pre-composting
followed byvermicomposting.Eisenia fetida(red wigglers) species of earthworms used in the
vermicomposting processes. The results indicate that, a system thatcombines the two
processes not only shortens stabilization time, but also improves the productsquality.
Combining the two systems resulted in a product that was more stable and
consistent(homogenous), had less potential impact on the environment and for compost.
Vermicompostingsystem, the product met the pathogen reduction requirements.
