| BMC to put microbes to work at Deonar
The BMC is planning to seek help from
microorganisms in dealing with the growing garbage crisis at Deonar
dumping ground. A pilot project will soon be started at the dump,
wherein the corporation will unleash the power of bacteria to deal
with piles of garbage.
Called the bioculture method, the project will test if special microbes
hasten the composting process at the dumping ground. If successful,
the project will curb the foul smell emanating from the garbage as
well create more space for extra — both because the cycle of turning
garbage into compost will roll faster.
Says Mohole, deputy chief engineer, solid waste department (eastern
suburb), “We have already invited tenders for this process and work
is expected to begin in a couple of months.”
Explaining the working of the project, Mohole says, “Effective Microbs
(EM), which comprises several forms of bacteria, will be added to
the garbage. The bacteria are expected to turn the garbage into sellable
compost in very little time.”
At the end of the composting process, the manure generated can will
be distributed or sold to residents or bulk purchasers. Mohole pegs
the cost of the project at Rs 4 lakh.
“We expect to treat 300 metric tonne of garbage through the pilot
project,” he says, adding that the bacteria to garbage proportion
will be 1 kg and 1 tonne, respectively.
Normally, it takes around 45 days for the garbage to convert into
compost. This leads to huge accumulation garbage at the dump. Apart
from the foul smell, the garbage also often catches fire, which adds
to the air pollution in the area.
“If the project is successful, we can save around 15 days to 30 days
per cycle. This will go a long way in cutting down the smell and smoke
at the dump,” says Mohole.
Apart form this, the BMC is also trying to explore options like using
the garbage at the dump to create non-conventional forms of energy
that can be used as fuel in at least some industries. However, details
of this project are yet to be worked out.
