Green & clean technology is the only solution for human survival on earth. This research paper is focused on the methods of green manufacturing to reduce the waste and pollution. Green manufacturing (GM) is a term used to describe manufacturing practices that do not harm the environment during any part of the manufacturing process. The paper also highlights development of a product with less wastage. Many numbers of organizations have begun working towards implementation of Green Manufacturing (GM) because of increased concerns about the pollution increase, natural resources depletion and global warming. The CO₂ emission and the waste that is generated from the industry is one of the main factors for the environmental degradation which leads to global warming and acid rain. Green product, green manufacturing and green energy are essential for this purpose. Specific emphasis has been laid on polluting iron and steel industries.
