Inadequacies of solid waste management among public, private and community based organisations and its impact on health

Introduction

Solid waste is any material which comes from domestic, commercial, and industrial sources arising from human activities; which has no value to people who possess it and is discarded as useless. In the early days, waste disposal did not pose difficulty as habitations were sparse and land was plentiful. Waste disposal became problematic with the rise of towns and cities where large numbers of people started to congregate in relatively small areas in pursuit of livelihoods. Waste has become a major health hazard that undermines people’s right to a safe life. All forms of waste, municipal, biomedical or industrial if not treated and disposed off carefully are a threat to the health of people as well as environment (Mohan, 2003).

If current trends continue, the world may see a fivefold increase in waste generation by the year 2025. Moreover, waste generation rates are set to more than double in the next twenty years in low and middle income countries, the costs of managing the waste is also expected to witness a steep rise. The differences in efficiency in waste management in developed and developing countries remain wide despite expenditures are comparable or similar. Low income countries spend most of their expenditure on waste collection rather than disposal while developed countries emphasize on reduction and segregation at source.

The collection, transfer and disposal of waste is generally the responsibility of metropolitan governments in both developed and developing worlds. Government agencies in urban areas spend about 20-40% of revenues on waste management; yet they are unable to keep pace with the scope of the problem (Zerbock 2003).

Waste management is a growing problem in in most cities. Increasing urbanization, rural-urban migration, rising standards of living and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities. The increase in solid waste generation has not been accompanied by equivalent increase in the capacity of urban authorities to deal with this problem. The proper management of waste has thus become one of the most pressing and challenging environmental problems in many cities in the world (JICA, 1998). The inability of city authority to collection and disposal waste, has led to indiscriminate dumping, poor sanitary conditions, and incidences of environment-related health problems (Ikiara, 2006).

Urbanisation and Waste Management

Global perspective

Proper management of waste has been a critical aspect in urban areas, especially in mega cities which are major centres of waste generation. Irregular collection or non-collection, transportation in open vehicles, and environmentally unsafe methods of processing and disposal of waste are common features of a large number of urban areas across the developing countries (JICA, 1998).

The collection, transfer and disposal of waste have been generally assumed by metropolitan governments in both developed and developing world. This constitutes a basic and expected government function. The format varies in most urban areas where solid waste is collected either by a government agency or private contractor. Despite the fact that developing countries do spend about 20 to 40 per cent of metropolitan revenues on waste management, they are unable to keep pace with the scope of the problem (Zerbock, 2003). In fact, when the governments of African countries were required by the World Health Organization (WHO) to prioritize their environmental health concerns, the results revealed that solid waste was identified as the second most important problem after water quality (Zerbock, 2003).

Waste management in all ramifications, is simply a planned system aimed at effectively controlling the production, storage, collection, transportation, processing and disposal of waste. Waste management is an important element of environmental protection. Its purpose is to provide hygienic, efficient and economic solid waste storage, collection, transportation and treatment or disposal of waste without polluting the atmosphere, soil or water system. The various steps involved in the management of solid waste from generation to the point of sanitary disposal are referred to as solid waste chain. It therefore means that the solid waste chain is the path trace by solid waste from generation to the final disposal point. The element of collection not only includes the gathering of solid waste, but also the hauling of waste after collection to the location where the collection vehicle is emptied.

Characteristics of Waste

Waste characterization is a waste stream analysis which involves a logical and systematic approach to obtaining and analysing data on one or more waste streams or sub-streams. Waste characterization provides an estimate of solid waste quantity and composition. Two commonly used methods of waste characterization are – material flow approach and site-specific study. However there is currently no agreed international standard for waste stream analysis or waste characterisation although many countries have national procedures for analysing their waste

(Karanja, 2005).

Waste Management Approaches

One of the recently developed waste management approach is ISSWM. The integrated sustainable solid waste management (ISSWM) was first developed in mid 1980s by a Dutch NGO called WASTE and further developed in 1990s by the Collaborative Working Group on Solid Waste Management in Low- and Middle-Income Countries. It then became a norm. The ISSWM is a system approach that recognizes three main dimensions including stakeholders, elements, and aspects.

The stakeholders are the people or organizations participating in solid waste management. This includes the waste generators who use the services, the service providers, the formal and informal private sector dealing with solid waste management, and other local or international institutions. Elements comprises the technical components of the waste management system starting from the generation of solid waste then the collection, transfer and transportation of waste to dumpsites or to treatment plant.

Solid Waste Regulations

International Conventions and Protocols

Basel convention

The Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal was adopted on 22 March 1989 by the Conference of Plenipotentiaries in Basel, Switzerland, in response to a public outcry following the discovery, in the 1980s, in Africa and other parts of the developing world of deposits of toxic wastes imported from abroad.

The overarching objective of the Basel Convention is to protect human health and the environment against the adverse effects of hazardous wastes. Its scope of application covers a wide range of wastes defined as “hazardous wastes” based on their origin and/or composition and their characteristics, as well as two types of wastes defined as “other wastes” – household waste and incinerator ash.

The Convention also provides for the establishment of regional or sub-regional centres for training and technology transfers regarding the management of hazardous wastes and other wastes and the minimization of their generation to cater to the specific needs of different regions and sub regions (article 14). Fourteen such centres have been established. They carry out training and capacity building activities in the regions.

Bamako convention

The Bamako convention (in full: Bamako convention on the ban on the import into Africa and the control of transboundary movement and management of hazardous wastes within Africa) is a treaty of African nations prohibiting the import of any hazardous (including radioactive) waste. The convention was negotiated by twelve nations of the Organisation of African Unity at Bamako, Mali in January, 1991, and came into force in 1998.

Impetus for the Bamako Convention arose from the failure of the Basel Convention to prohibit trade of hazardous waste to less developed countries (LDCs), and from the realization that many developed nations were exporting toxic wastes to Africa. This impression was strengthened by several prominent cases. One important case, which occurred in 1987, concerned the importation into Nigeria of 18,000 barrels (2,900 m3) of hazardous waste from the Italian companies Ecomar and Jelly Wax, which had agreed to pay local farmer Sunday Nana $100 per month for storage. The barrels, found in storage in the port of Koko, contained toxic waste including polychlorinated biphenyls, and their eventual shipment back to Italy led to protests closing three Italian ports.

The Bamako Convention uses a format and language similar to that of the Basel Convention, but is much stronger in prohibiting all imports of hazardous waste. Additionally, it does not make exceptions on certain hazardous wastes (like those for radioactive materials) made by the Basel Convention. 

Environment Management and Coordination Act, EMCA 1999 (Sessional paper No.8 of 1999)

Conclusion

SWM is a growing problem in most, if not all urban centres. Use of crude equipment by waste collectors and transporters is a major challenge. Besides, unplanned housing has led to houses being in such close proximity, trucks would have a hard time accessing the interior parts of urban areas.

Based on the above, for adequate solid waste management, the following is suggested:

 There is a need to recognize, formalise and streamline the operation of CBO’s in waste collection so they have the same legal and operational status as Private Collectors;

 The CGN should fairly distribute the newly acquired trucks and compactors among all constituencies in Nairobi. These trucks should also operate daily. This will greatly boost waste collection.

 The CGN should be keen on recovering public land that has been grabbed. Besides other uses, such land can be allocated to sorting of waste.

 The CBOs should come together and form a union/sacco that will help them acquire funding for the activities. This is a more responsible approach compared to blaming the CGN on every failure.

 Government support is crucial to the recyclers, since they have no capital to invest in infrastructure and capacity building. Co-operative recycling should not be treated as a separate program, but rather be integrated into the county government solid waste program. Government recognition and commitment are essential in the success of these ventures.
