3. The term "technology" refers to the application of
knowledge for practical purposes.
The field of "green technology" encompasses a
continuously evolving group of methods and
Materials, from techniques for generating energy
to non-toxic cleaning products.

4. The goals that inform developments in this rapidly
growing field include:
Sustainability - meeting the needs of society in ways that
can continue indefinitely into the future without
damaging or depleting natural resources. In short,
meeting present needs without compromising the ability
of future generations to meet their own needs.
"Cradle to cradle" design - ending the "cradle to grave"
cycle of manufactured products, by creating products that
can be fully reclaimed or re-used.
Source reduction - reducing waste and pollution by
changing patterns of production and consumption.

5. Examples of green technology subject areas
Energy :Perhaps the most urgent issue for green
technology, this includes the development of
alternative fuels, new means of generating energy and
energy efficiency.
Green chemistry
The invention, design and application of chemical
products and processes to reduce or to eliminate the
use and generation of hazardous substances.

6. Green nanotechnology
Nanotechnology involves the manipulation of materials at
the scale of the nanometer, one billionth of a meter. Some
scientists believe that mastery of this subject is forthcoming
that will transform the way that everything in the world is
manufactured. "Green nanotechnology" is the application of
green chemistry and green engineering principles to this
field.

7. Green Chemistry also called sustainable chemistry is the design of chemical
products and processes that reduce or eliminate the use and generation of
hazardous substances. As a chemical philosophy, green chemistry applies
to organic chemistry, inorganic chemistry, biochemistry, analytical
chemistry, physical chemistry and even chemical engineering. While green
chemistry seems to focus on industrial applications, it does apply to any
chemistry choice.
The term green chemistry was coined by Paul Anastas in 1991.
This emerging field has gained importance not only in the areas of research
and development but in the world of both academics and industry.

9. Zero Waste Technology is the essence of green chemistry. Methodologies
are devised for the synthesis in such a manner that there are no products
formed during a reaction, or if any waste by products are formed they can
be used as raw materials or starting materials of other units.
Thus Zero Waste is the recycling of all materials back into the nature or the
market place is a manner that protects human health and environment.
