1) Vermicomposting is a process that uses worms to turn organic waste into a nutrient-rich compost through decomposition. It is a sustainable way to treat biodegradable agricultural waste and food scraps. 2) The common worm used is Eisenia foetida, which eats through food waste and excretes castings that enrich the soil. Vermicompost contains nutrients that can help plants grow without the need for chemicals. 3) Vermicomposting has benefits like reducing landfill waste, saving money on fertilizers, and potentially generating income from the sale of worms and produced compost. It is a simple, effective method for sustainable waste management and agriculture.

Back to Basics

3. INTRODUCTION:
 It estimated that in India nearly 700 million tonnes of
organic waste are generated annually which is either
burned or land filled.
 The lorge amount of the agro waste generated from the
market area created the major environmental problems.
 Vermicomposting is the best biotechnology to reduce the
load on the treatment and disposal of biodegradable agro
waste.

4. What is Vermicomposting?
 The raising and production of earthworms and
harvesting worm castings .
 Using worms to decompose organic food waste, turning
the waste into a nutrient-rich material capable of
supplying necessary nutrients to help sustain plant
growth.
 Vermicompost is similar to regular compost, except that
worms take part in the composting process.

5. Overview
 Vermicomposting is a special type of composting which uses
certain earth worms.
Vermicomposting is already being used worlwide for treatment
of organic waste, sewage sludge, manure, kitchen waste etc.

7. MATERIALS & METHODS
 Collection and rearing of the earthworm Eisenia foetida.
 Collection of biological waste.
a) Animal dung (cow,buffalo,elephant,goat,horse,pig,sheep) .
b) Agro-waste(wheat straw,banana pills,gram rice).

9. Benefits of
Vermicomposting

10. Benefits
 Input Waste, Get Black Gold as an output!
 Save Money by letting worms make compost for you free
and fast!!
 Be Eco-conscious/Green by diverting food waste from the
landfills
 Reverse the damage from years of bad soil management:
Over fertilization, Chemicals, and over tilling.
 Potential to make money

Benefits of
Vermicomposting
1. Recycles waste in an
environmentally-friendly way
2. Keeps more garbage out of
landfills
3. A sustainable way to produce
low-cost nutritionally-valuable
organic fertilizer
4. Very little time or labor is required
5. It can be done indoors
odorlessly!
6. Income generation through sale
of worms and vermicompost or
both!
7. Materials available to everyone

Chemicals
fertilizers actually
destroy most life
forms in the soil
Benefits of Vermicompost:
It Feeds the Soil while it
Feeds the Plants

13. Convert food waste into fertilizer!
Saves food waste from entering our Landfills
We are also wasting 67
million food every
year , according to a
government study .
Our society wastes 1/2
of all food that it
produces

14. Why is Vermicompost Important?
 Vermicompost or worm fertilizer is strictly organic.
Vermicompost is used as an organic fertilizer in
agricultural gardens. Vermicompost enriches the soil,
creates an ecologically safe system of food production,
and raises land productivity. By using vermicompost in
gardens, harmful chemicals and pesticides are no longer
needed in the cultivation of crops.

15. Summary and Conclusions
 Simple, effective
 Easily preparable and less expensive.
 Contributes to sustainability by reducing
landfilling, closing loop from food chain.
 Vermicompost is also a boon for the farmers and
unemployed person.
