The demographic explosion recorded over the last decades
in Kinshasa resulted in a growing demand for consumer goods, which has led to
increased production of solid, liquid and gaseous wastes. The permanentpresence of these unrecognized resources in the urban environment constitutes athreat, causing several diseases. Thus, resulting in the decrease in life
expectancy of human population. Interest in waste management is evident and is
observing in several researches, but also by the proliferation of international
meetings of reflection revolving mainly around the environment and safety.
Stockholm 1972, Kyoto 1977, Nairobi 1991, Rio de Janeiro 1992 and Johannesburg
2002 summits can be considered as those used engine about the awakening global
consciousness on environmental issues.Through various efforts around the world, it appears thatthe sanitation level is especially improving in developed countries. The case
of some European countries that minimize spread risk of diseases that typically
generate the excreta through the drain, transportation and disposal of sludge can
be evoked.
