It involves processing of various types of non-toxic,
natural/biodegradable waste as feeding material, to a product, with
the help of deep burrowing earthworm Pheretima
elongata and several microorganisms. The microorganisms bring
about aerobic degradation of these wastes in a speedy manner if
they’re provided with favourable conditions of temperature,
moisture, pH, air and growth nutrients. Burrowing earthworms provide
these ideal conditions for the proliferation of beneficial
microorganisms due to there burrowing activity. The product so
formed is a rich biofertilizer containing several micronutrients,
enzymes, vitamins, antibiotics, cultures of microorganisms and
cocoons of Pheretima elongata.
Advantages of the
1. The process being
aerobic, is devoid of any foul smell that normally accompanies the
waste and its decomposition.
2. The process takes
place at a pH value of 7-7.5, therefore does not attract pests like
flies, mosquitoes, rats, ants and cockroaches.
3. The process
requires very less water (about 50% of moisture level).
4. The process is
extremely environment friendly as no chemicals are used for
controlling the process.
5. No recurrent
expenditures on materials required, hence most inexpensive.
6. It doesn’t
involve turning of garbage as the process is a continuous one which
involves spreading of garbage or waste in layers everyday, therefore
process is least labor intensive.
7. As the earthworms
are deep burrowing and light sensitive, they prefer to remain inside
the soil and not come out of the pits or the pots and therefore
these are very useful for processing the waste at source such as
individual households, societies etc. without the fear of earthworms
8. The process is a
continuous one and hence no need to harvest the product periodically
which requires labour. The harvesting can be done as and when
9. The product formed
is a culture and can be used for processing of diverse solid and
liquid organic waste and not just a fertilizer for plants.
10. The product is
also very useful for improving soil quality chemically, physically
11. It is used for
sustainable agriculture, wasteland development and in checking the
Methodology used for
It involves the following stages:
1. Vermibed preparation
3. Garbage loading
If the processing is done at society level, most of the
requirements can be met with from the existing facilities and man
power. Additional costs are required for:
1. Designing and
commissioning of the vermibed (one time expenditure).
2. Regular loading,
supervision and monitoring of the process by the expert for a
certain period (recurring expenditure).
The activity at the end of one year not only can support
itself but can also become profitable.
