Pollution free environment is now-a-day considered as an important criterion of
development for almost every country of the world. Thus, selection of materials and
manufacturing processes for a particular product becomes very crucial and must pass
through numerous regulations to achieve green atmosphere. In order to achieve this goal,
close coordination among the designer, material scientist, manufacturing engineer and
environmental expert is needed. Starting from the design to the final product including
the recyclability and waste disposal, each and every step must be carefully considered,
planned and coordinated before manufacturing starts. This is because; any change in
design or material and associated technique during manufacturing becomes more and
more expensive as work progresses. Agro-based and industrial nations of the world have
started to show their interest on health hazard, recyclability and to generate clean and
environment friendly energy. At the same time, emphasis must be given on pollution free
green environment so that man-made disaster may not occur.
