Abstract--Pollution prevention(P2) at the source of production instead of pollution control after waste streams occurred is preferred activity
nowadays. Nanotechnology has the potential to improve the environment, both through direct applications of nano-materials to detect,
prevent, and remove pollutants and toxic materials, as well as indirectly by using nanotechnology to design cleaner industrial processes and
create environmentally responsible products and to provide more sensitive detection systems for air and water quality monitoring. In this
paper polluton prevention activities are examined in detail in terms of nano production structures/properties. It is expected to have that nano
production has less negative environmental impact on ecosystem and humanbeing, also providing us better methods to deal with pollution of
hazardous materials on environment.
Nanotechnology is considered to play a key role in the
arranging of current environmental engineering and
science. Cost-effective technologies for remediation,
pollution detection, catalysis and others are under
development [1]. There is a big expectation that
nanotechnological applications and products will lead to a
cleaner and healthier environment [2]. Maintaining and
re-improving the quality of water, air and soil, so that the
Earth will be able to support human and other life
sustainably, are one of the great challenges of our time.
The scarcity of water, in terms of both quantity and
quality, poses a significant threat to the well-being of
people, especially in developing countries. Great hope is
placed on the role that nanotechnology can play in
providing clean water to these countries in an efficient and
cheap way [3]. On the other hand, the discussion about the
potential adverse effects of nanoparticles has increased
steadily in recent years and is a top priority in agencies all
over the world [4, 5]. Statistics shows that the hits for a
search for risk related to nanotechnology in the Web of
Science is increasing. The same properties that can be
deleterious for the environment can be advantageous for
technical applications and are exploited for treatment and
remediation.
The toxicity of some nanoparticles can be used for water
disinfection where killing of microorganisms is intended,
whereas the same property is unwanted Nanotechnology.
The catalytic activity of a nanoparticle can be
advantageous when used for the degradation of pollutants,
but can induce a toxic response when taken up by a cell.
The high sorption capacity of certain nanoparticles is
exploited for the removal of organic and inorganic
pollutants while this property may also mobilize
sequestered pollutants in the environment. The engineering
of nanoparticles that are easily taken up by cells will have
a huge impact on medicine and pharmacological research,
but the dispersion of such particles in the environment can
lead to unwanted and unexpected effects. By using these
properies of nanotechnology in terms of pollution control
may be Preferred, because it is possible use it extensively
for treatment of waste streams.
But critical part of today’s approach is to pollution
prevention at the source. For this reason in terms of
pollution prevention (P2) the total system must be
analyzed simultaneously to find the minimum economic
option. Experience in all industries teaches that processes
that minimize waste generation at the source are the most
economical. For existing plants, the problem is even more
acute. Even so, experience has shown that waste
generation in existing facilities can be significantly
reduced( greater than 30 % on avarage) while at the same
time reducing operating costs and new capital investment.
Drivers to begin P2 programs are; Legal requirement,
Public image and societal expectations, Large incentive for
reducing new capital investment in end-of-pipe treatment,
Significant return by manufacturing costs, Need to
increase revenues from existing equipment, Corporate
goal, ncreasing effectiveness by using Nanotechnology,
In summary, polluton prevention activities are examined
in detail in terms of nano production structures/properties.
It is expected to have that nano production has less
negative environmental impact on ecosystem and
humanbeing, also providing us better methods to deal with
pollution of hazardous materials on environment.
