STERN J., SOUTHGATE D., STRASMA J. Improving garbage collection in Latin America's slums: some lessons from Machala, Ecuador in Resources, conservation and recycling, Elvesier, 1997, vol. 20, n&#176;3, p. 219-224     The challenge of improving garbage collection in Latin American slums is illustrated by the case of Machala, Ecuador, a port city with a population of approximately 200000. For many years, solid waste services have been provided exclusively by a unionized municipal department. By and large, it has performed inefficiently, and virtually no garbage is collected in the city's poor neighborhoods, where 100000 people reside. Better service for Machala's slums requires the use of appropriate technology. To be specific, large tricycles equipped with a 1 m3 box lend themselves well to garbage collection in areas through which motorized vehicles cannot easily pass. With support from international development agencies, a small independent enterprise has been created to operate the tricycles as well as a truck for hauling garbage from transfer points to the city dump. Although the new system is cost-efficient, there are impediments to the replication of this scheme in other locations. Legal and institutional reform is needed to facilitate municipal contracting with enterprises like Machala's.  Article payant disponible sur Refdoc.fr  Pour accéder aux informations ...
