The expected environmental catastrophy is predominantly in creating unnecessary waste, change of climate, and unreasonable excerption of irreversible resources. Chemical Process Industries (CPI) belong to the more industrious productions. Unfortunately, despite some real and many pretended efforts to limit the damage to the environment by the CPI during their production activities or through their products, in the end the lerge productivity of this branch is to a considerable degree at the expense of the environment. This is the reason why CPI are regarded lataly by even slightly greenish groupings as the environmental fiend No.1. In the present contribution we tackle some problems which must be solved as the main challenges of the chemical engineering profession (CEP) for the next millenium.
