Waste segregation and potential for recycling -A case study in Dar es Salaam City, Tanzania

ABSTRACT Waste segregation is an important component in the waste management chain as it makes it possible to realize effective Reuse, Recycling and Recovery (RRR). Unfortunately, it has received little attention and is normally informally practiced in most developing countries (DC). It is also affected by lack of awareness, weak regulatory frameworks and enforcement, lack of economic incentive and a low priority in planning. This study was conducted in Kimara ward in Dar es Salaam city in Tanzania. It employed interviews, household surveys and waste measurements, to establish the potential for RRR as well as the underlying factors that are related to the community perspectives and strategies for enhancement of RRR. Results show that the generation rate was 0.53 kg/Cap.day and the main type was food waste (>60% of the composition by weight). The study revealed further that reuse and recycling of plastics, electronics and metals are informally practiced and the selling chain is from household to waste collectors to recycling centers and finally to industries. The potential for RRR was found to be high but, it is affected by lack of facilities, inadequate enforcement of the policy as well as lack of awareness and strategies for its promotion. Community perceptions on what could be done to improve segregation include the provision of facilities for waste segregation and financial returns to the community from recycling business could promote RRR. Formulation of strategies to formalize and mainstream RRR into training programmes and adequate enforcement mechanisms are some of the recommended policy actions.
