Vermitechnology is an emerging solid waste management method that utilizes earthworms to convert organic waste into biofertilizer through their digestive processes. There are three main types of earthworms used in composting: anecic, endogeic, and epigeic, each playing a unique role in decomposition and soil health. Common species include Eisenia fetida for epigeic worms, Lumbricus terrestris for anecic worms, and Aporrectodea caliginosa for endogeic worms.

2. VERMITECHNOLOGY
 Vemitechnology is globally becoming a
popular solid waste management technique
 Vermitechnology is a process by which the
bioconversion of organic waste into a
biofertilizer due to earthworms activity. The
earthworms feed on the organic wastes and
the earthworms gut acts as bioreactor
whereby the vermicasts are produced.

3. TYPES OF EARTHWORMS
USED FOR COMPOSTING

Anecic : Earthworms feed on decaying organic
matters. Which are responsible for cycling
organic debris into humus
 Endogeic: These worms spending their lives
deep in the soil where they feed on decayed
matter and mineral soil particle. These worms
build burrows.
 Epigeic species : These are found in the natural
environment in the top soil layer where they feed
on decaying organic matter

5. EPIGEIC EARTHWORM
Examples: Eisenia fetida (commonly used in
composting), Lumbricus rubellus.

6. ENDOGEIC EARTHWORMS
Examples: Aporrectodea caliginosa,
Allolobophora chlorotica.

7. ANECIC EARTHWORMS
Examples: Lumbricus terrestris (common
nightcrawler), Aporrectodea longa.
