2. Environmental Engineering
Environmental engineering is the integration of science and
engineering principles to improve the natural environment (air,
water, and/or land resources), to provide healthy water, air, and land
for human habitation (house or home) and for other organisms, and
to remediate pollution sites. Further more it is concerned with
finding plausible solutions in the field of public health, such
arthropod-borne diseases, implementing law which promote
adequate sanitation in urban, rural and recreational areas. It
involves waste water management and air pollution control,
recycling, waste disposal, radiation protection, industrial hygiene,
environmental sustainability, and public health issues as well as a
knowledge of environmental engineering law. It also includes
studies on the environmental impact of proposed construction
projects.
3. Study of Environmental Engineering
Environmental engineers study the effect of technological advances on the
environment. To do so, they conduct hazardous-waste management
studies to evaluate the significance of such hazards, advise on treatment
and containment, and develop regulations to prevent mishaps.
Environmental engineers also design municipal water supply and industrial
wastewater treatment systems[1][2] as well as address local and worldwide
environmental issues such as the effects of acid rain, global warming,
ozone depletion, water pollution and air pollution from automobile exhausts
and industrial sources.[3][4][5][6] At many universities,
Environmental Engineering programs follow either the Department of Civil
Engineering or The Department of Chemical Engineering at Engineering
faculties. Environmental "civil" engineers focus on hydrology, water
resources management, bioremediation, and water treatment plant design.
Environmental "chemical" engineers, on the other hand, focus on
environmental chemistry, advanced air and water treatment technologies
and separation processes.
4. Environmental Industry
The term environmental industry[1] was defined in 1988 by
Environmental Business International Inc.[2](EBI) as all revenue
generation associated with environmental protection, assessment,
compliance with environmental regulations, pollution control,
waste management, remediation of contaminated property and
the provision and delivery of environmental resources.
This 14-segment definition and quantification of the
environmental industry has been adopted by the U.S. Department
of Commerce's Statistical Abstract [3], OECD[4], U.S. International
Trade Commission[5] and other government and private sources.
This is partly because environmental goods and services have
been inadequately covered in standard international classification
systems like the former Standard Industrial Classification (SIC)
and currently used North American Industry Classification (NAIC)
codes.[6]
5. Global Environmental Industry
The environmental industry represented
total revenues of more than $315 billion
in 2010, generated by about 30,000
private sector companies and more than
80,000 public sector entities in the United
States, employing 1,657,300
Americans.[7]
The global environmental market was
approximately $803 billion in 2010

8. Environmental Industry Segments
The environmental industry is comprised of
14 segments[9] of business activity divided
into three broad categories: services,
equipment and resources. Both private and
public sector revenues are counted as part of
the environmental industry. In some cases,
the estimate may not be actual revenues
generated by the public sector but total cost
allocation to a function like wastewater
treatment that may be only covered 60-70%
by user fees.

Recyclables in landfills
Recycling is a process to change materials (waste)
into new products to prevent waste of potentially
useful materials, reduce the consumption of fresh
raw materials, reduce energy usage, reduce air
pollution (from incineration) and water pollution
(from landfilling) by reducing the need for
"conventional" waste disposal, and lower greenhouse
gas emissions as compared to plastic production.[1][2]
Recycling is a key component of modern waste
reduction and is the third component of the "Reduce,
Reuse, Recycle" waste hierarchy
Recyclable materials include many kinds of glass,
paper, metal, plastic, textiles, and electronics.
Although similar in effect, the composting or other
reuse of biodegradable waste—such as food or
garden waste—is not typically considered recycling.[2]
Materials to be recycled are either brought to a
collection center or picked up from the curbside, then
sorted, cleaned, and reprocessed into new materials
bound for manufacturing.
16. Renewable energy
Renewable energy is energy that can be replenished easily. For years we have
been using sources like wood, sun, water, etc. for means for producing energy.
Energy that can be produced by natural objects like wood, sun, wind, etc. is
considered to be renewable.[1]
Water purification
Water purification: The whole idea/concept of having dirt/germ/pollution free
water flowing throughout the environment. Many other phenomena lead from this
concept of purification of water. Water pollution is the main enemy of this concept,
and various campaigns and activists have been organized around the world to help
purify water.[2]
Air purification
Air purification: Basic and common green plants can be grown indoors to keep air
fresh because all plants remove CO2 and convert it into oxygen. The best
examples are: Dypsis lutescens, Sansevieria trifasciata, and Epipremnum
aureum.[3]
Sewage treatment
Sewage treatment is conceptually similar to water purification. Sewage treatments
are very important as they purify water per levels of its pollution. The more
polluted water is not used for anything, and the least polluted water is supplied to
places where water is used affluently. It may lead to various other concepts of
environmental protection, sustainability etc
17. Environmental remediation
Environmental remediation is the removal of pollutants or
contaminants for the general protection of the environment. This is
accomplished by various chemical, biological, and bulk movement.
(encyclopedia of medical concepts)[5]
Solid waste management
Solid waste management is the purification, consumption, reuse,
disposal and treatment of solid waste that is undertaken by the
government or the ruling bodies of a city/town.[6]
eGain forecasting
Egain forecasting is a method using forecasting technology to predict
the future weather's impact on a building.[7] By adjusting the heat
based on the weather forecast, the system eliminates redundant use
of heat, thus reducing the energy consumption and the emission of
greenhouse gases.[8]
Energy conservation
Energy conservation is the utilization of devices that require smaller
amounts of energy in order to reduce the consumption of electricity.
Reducing the use of electricity causes less fossil fuels to be burned to
provide that electricity.

engineering
Scientists continue to search for clean
energy alternatives to our current power
production methods. Some technologies
such as anaerobic digestion produce
renewable energy from waste materials.
The global reduction of greenhouse gases
is dependent on the adoption of energy
conservation technologies at industrial
level as well as this clean energy
generation. That includes using unleaded
gasoline, solar energy and alternative fuel
vehicles, including plug-in hybrid and
hybrid electric vehicles.
