BUILDING RECYCLING RATES THROUGH THE INFORMAL SECTOR
The presence in waste of materials with positive value represents a potential source of livelihood for the urban poor. This was true for medieval cities and rapidly industrialising cities of Europe and North America in the nineteenth century and also applies to developing countries today (Wilson, 2007). It has been estimated that up to 2% of the urban population in Asia and Latin America depend on waste picking for all or part of their livelihood (Medina, 2000).
Many developing country cities aspire to modern waste management systems, which are associated with relatively high recycling rates of clean, source separated materials. Most already have informal sector recycling systems, which are driven solely by the revenues derived from selling recovered materials, even though they are saving the formal sector money by reducing waste quantities. There is clear potential for ‘win-win’ co-operation between the formal and informal sectors, as providing support to the informal sector, to build recycling rates and to address some of the social issues, could reduce the overall costs of waste management for the formal sector. This paper shows that recycling rates already achieved by the informal sector can be quite high, typically in the range from 20-50%; often up to half of this is in the form of clean, source separated materials collected directly from households and businesses by itinerant waste buyers (IWBs). Four country case studies provide a number of lessons on how this solid foundation could be used to build high recycling rates of clean materials.

Im Jahr 2014, zwanzig Jahre nach dem durch das Bayerische Staatsministerium für Landesentwicklung und Umweltfragen organisierten Wettbewerb „Der vorbildliche Wertstoffhof“, ist es sicher angebracht, sich dem Thema erneut zuzuwenden. Was ist aus den prämierten Wertstoffhöfen der Preisträger in den jeweiligen Clustern geworden? Wie hat sich das System grundsätzlich entwickelt? Wo geht es hin, wenn man die gesellschaftlichen Anforderungen aus demografischer Entwicklung, Ressourcenschutz und Klimarelevanz betrachtet?
MUNICIPAL SOLID WASTE MANAGEMENT IN THE LATIN AMERICAN AND CARIBBEAN REGIONS: TRENDS AND OPPORTUNITIES FOR IMPROVEMENT
© IWWG International Waste Working Group (10/2007)
Improving Municipal Solid Waste (MSW) management services in developing regions of the world is one the major challenges of sustainable urban development. As part of its commitment to help these regions in this effort, the World Bank commissioned a study in 2006 to review and rationalize the current state of municipal solid waste management in the Latin American and Caribbean (LAC) regions, and to recommend actions leading to improvements and greater private sector participation/investment.

Municipalities in both the developed and developing worlds have become inundated by the volume of solid waste which they must process in order to assure the health and safety of their populace. Particularly in the developing world there is a problem of meeting capital andoperations costs necessary to support the collection-transportation-landfill model of waste management which is currently prevalent in the developed world. In addition many districts in developing countries cities do not have adequate road infrastructure for the passage of waste collection and processing of solid waste, putting the population of their cities in more and more danger from epidemics and other health risks.
CURRENT STATE OF URBAN SOLID WASTE MANAGEMENT IN SOME CITIES IN AFRICA
© IWWG International Waste Working Group (10/2007)
Solid waste generation varies between countries, cities, and part of cities in Africa. Waste generation rates for the continent’s major cities such as Douala, Yaounde (Cameroun); Bujumbura (Burundi); Ibadan, Lagos (Nigeria); Tunis (Tunisia); Windhoek (Naimbia) and Kampala (Uganda) are estimated to range between 0.3 – 1.4 kg per capita. This gives an average of 0.78 kg per capita when compared to an average of 1.22 kg per capita for developed countries (Achankeng, 2003). A rapid growth in the volume of the waste generated and the variety are an inevitable consequence of the fast pace of urbanization in African cities.
