5. Green technology is a relatively new
field that has grown quickly as people
have become aware of their detrimental
effects on the environment, including
global warming and the greenhouse
effect.
It is a wide-encompassing field.
6. A “green technology” covers a constantly
evolving group of method and materials, from
methods and practices for generating energy
to non toxic cleaning products.
7. Green technology is one of the fastest
growing employment sectors and is surely
much more than a passing trend.
12. HYDROPONIC FARMING
•Hydroponics is the art and science of growing
plants without soil.
•Use 60% to 80% less water than conventional
outdoor farms by recycling every drop of
water that plants don't take up.
14. ISARD project : greening of agricultural production systems
through waste recycling
•ISARD project proposes to develop a comprehensive
integrated approach of applied knowledge in the field of
recycling of organic waste products in agriculture.
15. Organic Farming: Organic agriculture is an ecological
production management system that promotes and
enhances biodiversity, biological cycles and soil biological
activity. It is based on minimal use of off-farm inputs and on
management practices that restore, maintain and enhance
ecological harmony.

17. •Renewable Energy Sources
Solar Radiation
Wind Turbines
Hydroelectric :Currently largest source of electricity from
renewable.
Tidal Power :At high tide reservoir of water is
created which is allowed to ebb
through turbines located in dam.
21. •Recycling technology
Green Technology Recycling offers smart asset
disposal options to business, educational
institutions and government agencies.
•Sewage treatment and solid waste management
Sewage treatment is the process of
removing contaminants from wastewater and
household sewage, both runoff (effluents),
domestic, commercial and institutional.

28. Ability to meet strict product specifications
in foreign markets:
•Manufacturers in developing countries typically need
to meet stricter environmental requirements and
specifications to export their products to industrialized
countries.
•gain advantage and market share over competitors.
29. Reduction of input costs:
Green technology can improve production efficiency
through –
•the reduction of input costs,
•energy costs
• operating and maintenance costs, which can improve a
company’s competitive position.
30. Environmental image:
Adopting green technology can improve a
company’s environmental reputation, which is
crucial if other competitors and consumers are
becoming more environmental.
31. Ability to meet stricter environmental
regulations in the future:
Companies that invest in green technology are
more likely to be better equipped and ready for
stricter environmental regulations as well as
product specifications that are expected to be
imposed on them in the future.
33. High implementing costs
Lack of information
No known alternative chemical or
raw material input
No known alternative process
technology
Uncertainty about performance
impacts
Lack of human resources and skills

38. A specific low energy pulse is put into water.
The water molecules line up in a certain structure
and are split from the Hydrogen molecules. The
result is HNG.
On a molecular level, HNG is a specific ratio mix
of hydrogen and oxygen.
HNG instantly neutralizes carbon fuel pollution
emissions.
HNG combusts at a rate of 9000 meters per second
while normal Hydrogen combusts at a rate 600 meters
per second.
39. Hydro Nano Gas
•Air powered car
A compressed air car is a car that uses a
motor powered by compressed air.
The car can be powered solely by air, or
combined (as in a hybrid electric vehicle)
with gasoline, diesel, ethanol, or an electric
plant with regenerative braking.
40. Air powered car
The Indian automotive manufacturer has been
working with Motor Development International,
which is pioneering this technology, to make this
highly conceptual propulsion system a reality.
