Techno-economic assessment of municipal solid waste management in Jordan

Abstract

Mismanagement of solid waste leads to public health risks, adverse environmental impacts and other socio-economic problems. This is obvious in many developing countries around the world. Currently, several countries have realized that the way they manage their solid wastes does not satisfy the objectives of sustainable development. Therefore, these countries, including Jordan, which forms the case study presented here, have decided to move away from traditional solid waste management (SWM) options to more integrated solid waste management approaches. Unfortunately, in many developing countries like Jordan, the lack of adequate resources to implement the necessary changes is posing a serious obstacle. The present paper discusses the various practices and challenges of solid waste management in Jordan from both a technical and economic perspective. An overview of the current practices and their environmental implications in three major cities of the country, which generate more than 70% of the country’s solid waste, is presented. Recent literature on solid waste management in Jordan has been reviewed; and data on the total amount of municipal solid waste generated, compositional variations over the last two decades, and future projections are presented. The necessity, importance and needs of solid waste recovery and reuse are identified. The review of the legal frameworks indicated that there is a need for detailed and clear regulations dealing specifically with solid waste. The service cost analysis revealed that none of the municipalities in Jordan sufficiently recover the cost of the services, with more than 50% being subsidized from the municipalities’ budgets. The allocation of the available resources was analyzed and service performance indicators assessed. Factors that should be taken into consideration when making the decision to move from a traditional SWM approach to a more integrated approach are highlighted and suggestions for a more smooth transition are recommended.
