Given the conditions and challenges, the proposed
solutions is for the MCGM project in Mumbai based
on open technologies which could be Pyrolysis,
Gasification, Incineration (with or without pre-
processing) for the entire waste.
TCE as a consultant is working with MCGM on
the WTE project in the Deonar facility and the task
involves Detailed Project Report (DPR), PREPARING
BID documents and bid process management to
ensure the project is executed within the given
technological parameters and pollution control norms.
With 3000 tonnes being managed per day at the
Deonar facility, this is the largest project in the
country with this capacity in a single facility. The
scale of this equals the facilities in leading developed
nations in WTE.
The proposed plant is expected to produce 25-30 MW
power while treating 3000 MT MSW per day.
WTE plants are aimed at addressing the catastrophes
related to non-scientific dumping. The economic
viability hinges more on using the revenue streams
from the project to reduce the cost of scientific
waste management. The revenue streams from
WTE projects arise mostly from sale of electricity/
fuel generated from the waste management process.
In essence, this is a waste management process
with power as a by-product. Added to this is the
possibilities of benefits from the recycling/re-use
ecosystem. In the Indian scenario rag pickers make a
living out of the recyclable waste. However, in other
developed nations, the recycling component is a
revenue generating component.
There is also a cost element in overhaul and
maintenance of the plant with a life span of 20 years.
WTE success factors
WTE projects can be truly successful and
sustainable– both environmentally and economically,
provided the right technology is adapted. Every city
has its own socio-cultural lifestyles and the waste
generated reflects the city’s psyche. Rural waste
is different from the urban waste. The availability
of land and the density of the population in a given
site matters too. The type of waste and the waste
management technique used go hand in hand. For
instance, if the waste is well segregated, the waste
that can be incinerated may be kept within city
limits without adverse pollution effects while the
non-combustible waste, electronic waste, etc; can be
processed further away with the appropriate solution.
This can have a bearing on the logistics of waste
collection and hence a cost implication. In India
and other developing countries, the awareness and
consciousness on waste disposal and segregation
is almost nil. Hence, the most efficient technique of
waste management has to be selected by expert
consultants as it requires expertise to evaluate the
engineering technology and assess the economic
viability of the technology. For instance, pyrolisis is a
technique that is less polluting, more expensive and
