Industrial adviser: If two new processes under consideration are not substantially different in cost, then the less environmentally damaging process should be chosen
If, however, a company already employs an environmentally damaging process and retooling for a less damaging process would involve substantial cost, then that company should retool only if retooling is either legally required or likely to bring long-term savings substantially greater than the cost
Two new processes are being considered for the manufacture of ball bearings. The processes are similar, except that the chemicals used in process A will pollute a nearby river slightly more than will the chemicals for process B. Process A is also slightly cheaper than process B. The company should use process A.
