What can a Chemical Engineer do to assure that a

product or a process is sustainable?

Traditional economic criteria:

Analysis of profitability of a

chemical plant

New dimensions:

- Environmental sustainability

- Social solidarity

- Economic efficiency

How expensive is the transition?

Economic profitability

Sustainability as a central strategy

Environmental problems cannot

be solved by the level of thinking

that created them!


Rethinking processes from different viewpoints
