what causes global warming
What causes global warming
  • Excessive concentration of Green House Gas (GHG) is primarily responsible for Global Warming
  • Main constituents of GHG are CO2, CH4, CF4, NO2, SF6, various CFCs, …

Classification of Global Warming

  • Natural global warming
  • Anthropogenic (Man-made) global warming
contribution of natural or anthropogenic global warming
Contribution of natural or anthropogenic global warming

Man-made contribution to the Climate Change needs to be curbed.

Carbon contamination of our climate

  • Historically Carbon dioxide concentration is around 200 – 280ppm
  • Present concentration is 378ppm and it is rising at 1.5 ppm per year
  • Point of no return ≈ 400-450ppm? (Between 2040-2050)
  • We have 10-20 years is left to show that we can make

a difference?

three important methods to tackle global warming
Three important methods to tackle global warming
  • Promote large scale forestation
  • Reduce the `Carbon Footprint’- individual carbon contribution to climate
  • Transform `Conventional Projects’ into innovative `Clean Development Mechanism (CDM)’ Projects and get it certified by UNFCCC to generate `Carbon Credit’
  • How to integrate all three features in a single project
unep recommendation to curb carbon footprint
UNEP recommendation to curb Carbon Footprint

Since 2008 United Nations Environment Program (UNEP) recommending individual `CARBON FOOPRINT’ by changing their lifestyle

a innovative way of reducing the individual carbon footprint

`Fast Crematory Furnace or DrutaDahanChulli’ is an innovative project which reduces the `Carbon Footprint’ of every individual even beyond death !

Module-I: Furnace Unit (Traditional Furnace +)

  • Two brick platforms: Each with Length 7ft, Breadth 2.6ft, Height 2.6ft from Finished Ground Level (FGL)
  • Distance between two brick platforms: 3 ft
  • Rail (Horizontal): 3 ft (6 numbers)
  • Rail (Vertical): 3.6 ft (2X6 numbers)
  • Base of the furnace: Slightly U (concave) shaped
  • Size of air flow outlet duct penetrating one side of brick platform : 13in X 13in

Technical specification of DDC

Module-II: Blower Unit

Air Tunnel

  • Length of air flow duct (From Blower House to base of the furnace): Approx 10 ft
  • Shape of air flow duct: Box-shaped, focused towards furnace and covered by air-tight slab
  • Inlet size of air flow duct: 2ft X 2ft
  • Outlet size of air flow duct: 13in X 13in
  • Diameter of air blower (Fan): 2 ft
  • Speed of fan: Standard RPM available in market
technical specification of ddc2
Technical specification of DDC

Air Regulation

  • Regulator-I (Optional): Movable iron plate of size 15in X 15in to control air through the duct manually
  • Regulator-II: Two movable iron doors each of size 3.4ft X 2.6ft on both open sides of furnace

Post cremation cleaning arrangement

  • Underground water reservoir
  • Water pump with hose pipe
  • Drain to flow out debris after each cremation
why ddc is a green project
Why DDC is a `Green Project’ ?

A conservative estimate:-

  • Assuming 800 corpses are burnt per year, the DDC project economizes about 10kg of firewood than the Traditional Furnace and saves at least 1 man-hour per corpse:

a) Goodbye to Tire Derived Fuel (TDF) from Silchar Cremation Ground

  • Reduces individual `CARBON FOOTPRINT’ by eliminating harmful TDF

b) In 1 year DDC saves 21 days man-hour approximately

*X-Y=10 kg

  • c) In 1 year DDC saves 80 Quintal of firewood approximately

Recognition by SRISTI & Honey Bee Network of IIMA

Innovated by

Kanti Bhusan Sen

`

`Green Living, Green Death’

“The range the innovations made by Prof Sen touched not only lives but also the deaths. He invented the DrutaDahanChullior Fast Burning Furnace in 1989 which can be called a green furnace for cremation. It is alternative to the traditional cremation among the Hindus. . . .”

“The success of the DrutaDahanChulliin the crematory ground of Silchar for last two decades is a testimony of Green Consciousness spread by Prof Sen. He was given fitting finale in this furnace after his demise on June 9, 2004.”
