Commercially successful chemical manufacturing needs to take into acco
unt stringent environmental and safety constraints already in the earl
y stages of process development. All these necessary criteria have to
be considered simultaneously. Information must be exchanged between al
l stages of development. Development has to be made in parallel. Econo
mic, environmental, and safety criteria have to be considered broadly
with respect to time and space. Some research examples of the ' Safety
and Enviromental Protection in Chemistry Group' of ETH are briefly sk
etched.
