Vermicompost unit
VERMICOMPOST UNIT :: TEZPUR UNIVERSITY
Vermicomposting technology relies upon the conjoint action of earthworms and microorganisms to rapidly transform varied types of solid wastes. Considering the simplicity and flexibility of the technology, a vermicompost unit was established in January 2009 in the University under the supervision of Horticulture Section. The prime objectives are to recycle biodegradable waste fractions in a sustainable manner and curtail the cost of purchasing organic manure from market for landscaping ventures. Presently, the unit is running successfully to fulfill the need of organic manure for plantation/gardening works of the University. So far, the ready-to-use vermicompost is produced entirely from garden waste (grass) and leaf litters of the campus. The unit has waste accommodating capacity of about 16.5 m3, i.e., about 10 quintals (on fresh weight basis) at a given time. On an average, one vermicomposting period (or one batch) takes about 60-90 days depending on the nature of feedstock. Epegeic earthworm species (Eisenia fetida, Eudrilus eugeniae, and Perionyx excavatus) are applied at a rate of 10 worms/kg (approximately) feedstock to carry out the composting process. Approximately 126 quintal vermicompost has been produced in the last five years (w.e.f April-2016 to March-2021). The produced vermicompost is used for all sorts of plantation and landscaping activities at the University. The unit is ready for expansion to accommodate various other kinds of biodegradable solid wastes generated in the University.
