Prevention by recycle at source
World over we are seeing discussions about green and green related issues. Chemical Industry is no exemption. There is a great need to develop and practice eco-friendly processes for manufacturing products avoiding chemical pollution and waste generation. When the chemical products are designed keeping in mind the principles of green chemistry and E-factor, the enormous amount of waste produced by the industry can be kept under control.
The relevance of E-factor should be recognized at the design stage itself for any product so that it comes in harmony with the green concept. E-factor helps develop new processes and chemical products without harming the environment. It stresses on design of safer, biodegradable and less hazardous useful chemical products utilizing atom economic and energy efficient processes.
High Volume Products generate huge quantities of waste like H-Acid, DASDA, Paracetamol, Phenylephrine, Pigment CPC, Violet23 and Pendimethylene, which are extremely deadly harmful to the mankind. The key is prevention, not control. It is important to ensure proper scale-up through appropriate mixing, reactor design and engineering to have uniformity over large-volume operation. This is where green engineering plays a critical role in prevention by recycle at source at industrial scale. Green Chemistry is taking an independent form as an amalgam of other chemical disciplines, especially organic, inorganic and biological chemistry.
