5. Branches of Green Technology
• Green Chemistry
• Green Energy
• Green IT
• Green Building
• Green Nanotechnology

6. GREEN
CHEMISTRY

7. • Green Chemistry is the design of chemical
products and processes that reduce or eliminate
the generation of hazardous substances.
• Whereas environmental chemistry is
the chemistry of the natural environment, and
of pollutant chemicals in nature,
green chemistry seeks to reduce
and prevent pollution at its source.
• While no reaction is perfectly green, therefore
there are 12 principles are implemented.
Green Chemistry

8. 12 Principles of Green
Chemistry

9. Chemicals are marked as a
 Green circle ( )- The chemical is safe to use and
it does not cause any harm to human health and
environment.
Ex: citric acid
 Green half-circle( )The chemical is expected to be
of low concern based on experimental and modeled
data.
Ex: Aspartic acid, Monosodium –D-glucoheptone
Identification of Green
Chemicals

10.  Yellow triangle – ( )This chemical has some
hazard issues.
Ex: Terpinolene, Methyl benzoate
 Grey square - ( )This chemical will not be
acceptable for use in products.
Ex: Bis(2-ethylhexyl) sodium sulfosuccinate and
Benzyl alcohol (Flagged on 20/12/2013 for removal
from list in 12 months)
Identification of Green
Chemicals

11. Goals of Green Chemistry
1. To reduce adverse environmental impact, try
appropriate and innovative choice of material & their
chemical transformation.
2. To develop processes based on renewable rather than
non-renewable raw materials.
3. To develop processes that are less prone to
obnoxious chemical release, fires & explosion.
4. To minimize by-products in chemical transformation
by redesign of reactions & reaction sequences.
5. To develop products that are less toxic.

12. Goals of Green Chemistry
6. To develop products that degrade more rapidly in the
environment than the current products.
7. To reduce the requirements for hazardous persistent
solvents & extracts in chemical processes.
8. To improve energy efficiency by developing low
temperature & low pressure processes using new
catalysts.
9. To develop efficient & reliable methods to monitor
the processes for better & improved controls.

13. GREEN ENERGY:
Energy of Future

14. GREEN ENERGYRenewable energy is energy that comes
from resources which are continually
replenished such
as sunlight, wind, rain, tides, waves and
geothermal heat. About 16% of global
final energy consumption comes
from renewable resources, with 10% of all
energy from traditional biomass, mainly
used for heating, and 3.4%
from hydroelectricity. New renewables
(small hydro, modern biomass, wind,
solar, geothermal, and biofuels) accounted
for another 3% and are growing very
rapidly. The share of renewables
in electricity generation is around 19%,
with 16% of electricity coming from
hydroelectricity and 3% from new
renewables.
Green Energy

15. GREEN ENERGY
 Green energy comes from
natural sources such as
sunlight, wind, rain, tides,
plants, algae and geothermal
heat.
 These energy resources are
renewable.

17. If all computers worked from
home ONE day a week, 5.85
billion fewer gallons of oil
would be used EACH year.
The average server has
roughly the same annual
carbon footprint as
an SUV doing 15 miles-per-
gallon.

18. Green Information Technology
• Green computing is the practice of using
computing resources efficiently.
• Designing , manufacturing and disposing
Computer, servers with no impact on the
environment.
• To reduce the use of Hazardous materials,
maximize energy efficiency during product’s
lifetime.

19. Energy star
• One of the first manifestations of the green computing
movement was the launch of energy star program back in
1992.
• Energy Star served as a kind of voluntary label awarded to
computing products that succeeded in minimizing use of
energy while maximizing efficiency.
• Energy Star applied to products like computer monitors,
television sets and temperature control devices like
refrigerators, air conditioners, and similar items.

20. GREEN BUILDING

21. Green Building
• Green building (also known as green construction or
sustainable building) refers to both a structure and the using of
processes that are environmentally responsible and resource-
efficient throughout a building's life-cycle: from siting to
design, construction, operation, maintenance, renovation, and
demolition.
• Sustainable design (also called environmental design,
environmentally sustainable design, environmentally
conscious design, etc.) is the philosophy of designing physical
objects, the built environment, and services to comply with the
principles of social, economic, and ecological

22. Concept
• The `Green Building' concept is gaining importance in various
countries, including India. These are buildings that ensure that
waste is minimized at every stage during the construction and
operation of the building, resulting in low costs, according to
experts in the technology.
• The techniques associated with the `Green Building' include
measures to prevent erosion of soil, rainwater harvesting, use
of solar energy, preparation of landscapes to reduce heat,
reduction in usage of water, recycling of waste water and use
of world class energy efficient practices.

23. Importance of Green building
As green construction is the practice of creating
structures and using processes that are
environmentally responsible and resource-efficient
throughout a building's life-cycle: from siting to
design, construction, operation, maintenance,
renovation, and deconstruction.
The importance of this is it lessen the consume of
energy and the pollution as well because the more we
use nonrenewable energy the higher the risk of
pollution.

24. GREEN
NANOTECHNOLOGY

25. • Green nanotechnology is the study of
how nanotechnology can benefit the environment,
such as by using less energy during the
manufacturing process, the ability to recycle
products after use, and using eco-friendly materials.
Green Nanotechnology

materials to replace copper wiring Energy
Savings--Light Weight nano-composites
Increased miniaturization.

29. Green Resources and Organizations
• Environmental Protection Agency
• Green Power Partnership
• Energy Star
• GGEC
• U.S. Green Building Council (USGBC)

30. Laws for Green Technology
• The Environment (Protection) Act was enacted
in 1986 with the objective of providing for the
protection and improvement of the environment.
It empowers the Central Government to establish
authorities [under section 3(3)] charged with the
mandate of preventing environmental pollution
in all its forms and to tackle specific
environmental problems that are peculiar to
different parts of the country. The Act was last
amended in 1991.
