11. • Reusability
• Cradle to cradle products
• - advocated by Jeff Werner(designer at Beaty Bio diversity
museum, Canada)
• Not Cradle to grave products
• Can be reused by the manufacturer
• People are interested to return the reused as
they can enjoy discount in next purchase.
• Some of them have a second use
• E.g., different bottles, tea bags etc

12. • Innovation
• Renovation of existing product
• Eco-friendly expansion
• Newly built products

14. • Feasibility
• Identify the requirement of economic
feasibility
• Biogas, agri-recycling are on the examples of
feasibility
• Selection of technology is based on suitability.

15. • Areas of Green technology
• Green Chemistry
• Green Nanotechnology
• Green IT
• Green Buildings
• Green Energy

16. • Green Chemistry
• It is a philosophy of engineering and
chemical research which results in the
generation of products and processes
that reduce the utilization and
production of hazardous substances.
• This can be practically used in
biochemistry, analytical chemistry,
organic chemistry and towards physical
chemistry.
10

17. • Paul Anastas, the then scientific advisor to the
United States Environmental Protection
Agency and John C Warner, a American
chemist developed 12 principles of green
chemistry.
• Better to prevent waste before it is formed,
• Synthetic methods should be framed to
incorporate all materials.
• Generation of synthetic methodologies to
produce output which are no toxic to human
and to the environment,
11

18. • Design of chemical products in such manner
to conserve efficiency
• Use safer auxiliary substances (e.g., solvents,
separation agents, etc)
• Recognition of energy requirement for
environmental and economic impacts
• A raw material or feed stock should be
renewable
• Unnecessary derivatization (blocking group,
protection/de-protection, temporary
modification) is avoided
13

19. • Catalytic reagents are superior to
stoichiometic reagents
• Chemical products should be designed in such
a way that at the end of their function they do
not persist in the environment
• Analytical methodologies need to be further
developed to all for real-time
• Substances and the form of a substance used
in a chemical process should be to minimize
potential for chemical accidents
14

20. • Green Nanotechnology
• In this, outputs which are built up with the
help of nanotechnology is used to enhance
environmental sustainability.
• Nano Technology materials act as catalyst and
increases efficiency of current manufacturing
operations.
• The principles of green chemistry and green
engineering are used.
15

21. • Nanotechnology works with materials, devices,
and other structures with at least one dimension
sized from 1 to 100 nanometres.
• Nanotechnology is the engineering of functional
systems at the molecular scale.S
• In its original sense, 'nanotechnology' refers to
the projected ability to construct items from the
bottom up, using techniques and tools being
developed today to make complete, high
performance products.
• 1 nanometre = 1 billionth of a metre. = 10-9 of a
metre
11One billion = 109 1wwwwwwwww

22. • Woodrow Wilson Institute, Washington 2007,
in its report gives certain Green Nano
recommendations;.
• Identify green in Nanotechnology, for that a
life cycle approach should be used,
• Make sure that Nano products are being made
using green methods,
• Construct a database of current research in
green nano.
16

23. • Fields in which Green Nanotechnology can be
applied
• Energy,
• Health,
• Information and communication,
• Consumer goods,
• Heavy Industries.
17

24. • Green Buildings
• It refers to a building structure, where by
using process that are environmentally
responsible and maintaining resource
efficiency throughout the building’s life from
its designing to its demolition.
• known as green construction or sustainable
building.
18

25. • LEED (Leadership in Energy and
Environmental Design) is system which rates
buildings. This system was developed by
U.S.Green Building Council (GBC). The rating
system looks into six major areas;
• Sustainable sites,
• Water efficiency,
• Energy and atmosphere,
• Materials and resources,
• Indoor environment quality,
• Innovation and design process.

26. • Green IT
• Commonly called as Green computing or ICT
Sustainability which deals with the practice of
environmentally sustainable computing.
• It is the study and practice of designing,
manufacturing, using and disposing of
computers, servers, and associated sub-
systems
19

27. • San Murugesan, Member, Global Science and
Technology Forum (GSTF) Advisory Board in
his article, Hamessing Green I.T., defines the
field of green computing as, “the study and
practice of designing, manufacturing, using
and disposing of computers, servers, and
associated sub-systems—such as monitors,
printers, storage devices, and networking and
communication systems—efficiently and
effectively with minimal or no impact on the
environment.”

28. • Objectives of Green IT
• Limit the use of hazardous materials which are
harmful to environment,
• Ensure continual improvement in Green IT
position,
• Absorb Green IT Culture,
• Protect Natural resources,
• Promote recyclability or biodegradability of
obsolete and outdated products and factory,
• Obtain maximum energy efficiency during the life
span of the product,
• Better manage risk,
• Resolve resource constraints.
21

29. • Green Energy
• It is produced from alternative energy sources
that get powered by different natural events.
Here the energy is received from nature. The
main sources of green energy are water, wind
and solar energy
22

30. • Water energy – Water contains two types of
energy. The first being the kinetic energy, due
to this, it can flow and can form waves.
• The second, the potential energy which is
stored in the water is a useful source when
water is flowing.
• Hydro electric power is obtained from falling
water or stream.
• In India Only 16% of electricity has been
obtained as hydel power
23

31. • Wind energy
• It is the wind power which results in turning
wind turbines. Wind turbines produce
mechanical power or electricity from kinetic
energy.
• Indian wind energy has an installed capacity of
14158 MW
• India ranked 5th in terms of wind power.
24

32. • Solar energy
• Sun, the source of solar energy is one of the
richest bases of energy. These technologies
are characterized as passive solar and active
solar according the way in which sunlight is
captured.
• Active solar techniques include using
photovoltaic panels, solar thermal collectors
to produces energy. Passive solar technique
is not utilized for the manufacture of
electricity, but for light dispersing, designing
light space etc ie., solar architecture.

• ITC Limited
• Tata Metaliks Limited (TML)
• Tamil Nadu Newsprint and Papers Limited
• Wipro Technologies
• HCL Technologies
• ONGC
• IndusInd Bank
• IDEA Cellular
• Hero Honda Motors
• Suzlon Energy

36. Conclusion
• Green Technology is blessing to modern
industrialized world.
• The part and parcel of this technology can be had
from Green chemistry, Green nanotechnology,
Green building, Green IT and Green Energy.
• By introducing this knowledge, sustainable
development, preservation of nature,
conservation of human population and other
living beings, elimination of wastage, reusability,,
innovation of existing one, feasibility, etc are
made possible in a more successful manner.
