Though the focus of existing technologies is shifting towards Green Chemistry resulting into minimization of effluents from the process. It will probably take 10-15 years to achieve the ultimate zero discharge goal by implementing green chemistry in the processes.
Why alternative technology?
- The efficacy of well established technique of biological oxidation has reduced now a days.
- This is due to the development of many complex bio-refractory molecules due to the proposed modernization.
- Thus it is important to develop technologies, which can either be used as an alternative of conventional techniques.
