Sulfur Dioxide(SO2)
The release of SO2 to the atmosphere is the primary cause of acid rain in the world.
Fossil fuel combustion at electric power-generating plants accounts for about70% of
the emissions.
Coal, Oil, and all other fossil fuels naturally
contain some sulfur.
Volcanic eruptions are another more localized natural source of SO2
SO2 + OH. HSO3.

There are many contributors who are dealing with environmental issues and car industry is one of industries that the mostly challenged by forces in the world. Particularly, cars take part significantly in air pollution because of the fuel emissions.
of a secondary battery is not enough to replace the existing engine, it still needs to have both battery-powered motor and engine to generate enough power.
Clean Diesel
The diesel car has been recognized as the main culprit ofair pollution, but people are beginning to understand the diesel car in a different way. The clean diesel engine has a mechanism of compressed air and blast, and it

Introduction
The airline industry is in the midst of a dramatic restructuring that involves even more fundamental changes than those experienced following its deregulation in 1978. Yet, nearly three decades after deregulation, the industry remains fragile. Competitive pressure from low-cost carriers, the loss of consumer confidence in the air trans

Example of use of Biofiltration
(a) Biofilter, (b) Biological Trikling Filter, (c) Bioscrubber, (d) Air Lift Bioreactor
⑵ Principle of BIOFILTER
- BIOFILTATION applied to biofilter is decomposition method from various stinking material and VOCs including harmful emissions to harmless substance using Biological processes of microbial metabolism
- First,

So far, automobiles have been core transportation. Due to its importance to industrial development, policies were mostly automobile-centered. However, those have caused many side-effects such as traffic jam, parking space problem, air pollution, environmental degradation, and traffic accidents. We must respond to environmental changes by having a new form of transp
