A summary of the criticalities in adopting different types of
BATs is given in Fig. 5, where the two types of criticality that
the company must address, economics and know-how, are related
to each other.
As stated above, apart from the measures to extend the life
of the process baths, all the BATs are not economically critical.
The criticalities are concentrated in the availability and
maintenance of the know-how necessary for implementation,
i.e. the technology transfer process.
