Sanitary landfilling is considered to be the most appropriate means of final disposal of solid wastes. Currently in Tanzania, the cheapest method of developing a landfill is by making use of natural depressions or former borrow pits and mine pits. This paper examines the impacts associated with the relocation of a waste disposal site from a crude disposal site at Vingunguti to a new landfill site at New MECCO quarry in Kunduchi area, both in Dar es Salaam, Tanzania. The paper focuses on the fate of scavenging and solid waste recycling which are currently taking place at Vingunguti site and mining as well as food vending activities at the proposed new landfill site. Scavenging and waste recycling were found to be important sources of income for someindividuals in the city. Various items collected for recycling were found to be an important source of raw materials for some industries in Dar es Salaam. A total of 94% of all the miners were entirely dependent on stone mining and crushing as a sole means of income generation, and 68% of the miners had practised this activity for between 1 and 9 years. Finally the paper recommends that, selection of a waste disposal site should favour abandoned mines or borrow pits rather thanoperational ones. It also recommends that, waste recycling and scavenging be accommodated in other stages of the waste stream since they can not be practised at a sanitary landfill. [ABSTRACT FROM AUTHOR] |
