Since the invention of the wheel humans have never stopped inventing, churning one great innovation after another. In the beginning, when industries were built they would throw out the waste material in the water bodies depending on dilution to take care of it, but with time it has become a problem and measures need to be taken to make sure the water disposed off is treated well before leaving the factory. A similar trend has been seen with space where the dead satellites are now posing as man-made asteroid fields which is creating an array of problems for mankind. These similar problems translate to manufacturing processes too. The traditional methods applied were according to the past which requires a complete shift to a more sustainable model. Green manufacturing is a movement undertaken by the environmentally aware engineers and scientists to bring about this shift. Green Manufacturing can be defined as a method for manufacturing that uses renewable or non-fossil fuel energy, minimizes waste, promotes safe production, and limits the environmental impact. Apart from helping the planet immensely, green manufacturing has the ability to make the products safer for use and at cheaper rates hence making them more accessible to everyone. Different green manufacturing practices can be adopted by small-scale businesses and thus they can be utilized to boost the economy of developing countries. By making students and women the ambassadors of green manufacturing we can solve two problems i.e. environmental and economic sustainability at the same time.
Coming to statistics the United Nations declares a state of emergency for rising CO2 levels and calls upon nations to cut down their carbon emissions to about 50% by 2030. Green manufacturing is the way to go, it will be our long-term objective to solve the problem of ever-rising carbon emissions meanwhile allowing us to keep the industrial output to its full potential.
Apart from the three ‘R’ methods which are widely popularised, a new method is on the rise which started at the beginning of this millennium, which is known as ‘Upcycling’. It employs the use of creativity and sustainable thinking to create products of even more value using waste materials as raw products. Leading product manufacturers like Levis are employing this technique to manufacture Jeans from upcycled plastic waste. A shift in the core thinking of large corporations is being seen as the customers become more aware of the practices in this generation of information, who in turn demand products manufactured in a manner that does not take a toll on our planet even if the price of such products is higher than widely produced factory goods.
In conclusion, Green manufacturing is the need of the hour which can be implemented without any cross arguments unlike when we talk about shifting towards Nuclear energy from traditional sources which has its pros and cons. Making people aware and responsible towards this movement should be the aim of governments and educational institutions. Grants, competitions, and innovative campaigns can be utilized to attract our future generations to take up green manufacturing and sustainable thinking as their full-time profession!
