                attitudes is the most challenging and the most important step in applying
                the cleaner production concept.
                     The conceptual and procedural approach to production which demands
                all phases of the life cycle of products, must be addressed with the objective
                of the prevention or minimization of short- and long-term risks to humans
                and to the environment.
                     One factor in defining cleaner production is therefore the reduction in
                production costs that results from improved process efficiencies. In terms of
                investment the key difference is that investment in end-of-pipe technologies
                “treatment” is nearly always additional investment, whereas investment in
                cleaner production always pays. This has obvious implications for employ-
                ment and production cost.
                     A useful definition of cleaner production needs to take account of
                the distinction between technologies and processes. For example, a process
                may be made “cleaner” without necessarily replacing process equipment
                with cleaner components – by changing the way a process is operated, by
                implementing improved housekeeping or by replacing a feedstock with a
                “cleaner” one. Cleaner production may or may not, therefore, entail the use
                of cleaner technologies. Investment in cleaner production via the imple-
                mentation of clean technologies is clearly easier to identify than investment
                in cleaner production by any other means. Whatever the method employed
                to make production cleaner, the result is to reduce the amount of pollutants
                and waste generated and reduce the amounts of non-renewable or harmful
                inputs used.
                     Most of the developed and developing countries are working toward
                zero pollution not only in industrial sectors but also in vehicle emissions to
                reduce gaseous emissions to allowable limits and in other sectors such as
                construction and agricultural. To approach zero pollution, industry should
                prevent all pollutants from its effluent. The cleaner production hierarchy to
                eliminate all pollutants and approach zero waste/pollution should start from
                raw material selection through to recycling and all the way to product mod-
                ifications in order to avoid end-of-pipe treatment as will be explained through-
                out this chapter.



                2.2 Promoting Cleaner Production
                The UNEP launched the Cleaner Production Program in 1989 in response to
                the need to reduce worldwide industrial pollution and waste. Positive future
                expectations exist for the spread of the cleaner production concept, as it
                combines maximum effect for the environment with significant economic
                savings for any business.
                     Although it is up to industry to adopt a cleaner production concept, the
                role of government is required to encourage industries to begin their own CP
