Cleaner Technology

Technologies introduced to clean/scrub/recover the emissions are now know as "end of pipe" technologies. They are expensive and a wasteful way to deal with pollution. "Cleaner technologies" advocate going back to the source - as industrial hygiene intended. At source the environmental aspects of a process can be dealt with before they become environmental impacts.
