A framework for sustainable waste management : challenges and opportunities

Purpose - This purpose of this paper is concerned with the issue of designing and operating a sustainable waste management system, in rapidly growing urban areas. Some existing models for waste management and the extent to which they could be applied in a specific environment - Cairo for example - are discussed. An integrated framework which can serve as a basis for the development of a sustainable waste management system is proposed. Sustainability of the system, opportunities and challenges, material re-use and recycling, composting, incineration and energy production and land-filling are examined. Relevant waste management and cost sub-models inherent to the system are discussed. In addition, some other environmental and social aspects are also debated. The main focus of this paper is to provide some insights into the design of a more effective and integrated sustainable waste management system applicable for developing economies. Design/methodology/approach - An in-depth analysis is carried out for the existing models and approaches for waste management. This has led to the development of a framework which can be implemented. Findings - A comprehensive conceptual framework for a waste management system is developed. The major inputs and expected outputs are clearly identified. Originality/value - A comprehensive and complete system for waste management is proposed. This system can be operationalized and implemented with a view of sustainability
