Biodegradability of colorants - a priori design strategy or post facto treatability?

摘要

In an ideal scenario prevention need to be the top priority in a hierarchy of pollution management particularly in a highly mature one-and-a-half decade activity of colorants manufacture. The policy anywhere in the globe says that pollution should be prevented or reduced at the source whenever feasible. In the case of late realisation of pollution (which is often the case) there should be recycling strategy in an environmentally safe manner whenever feasible. When recycling happens to be a costly option as compared to the treatment pollution should be treated in an environmentally safe manner whenever feasible.
