Abstract
Waste minimisation is implemented worldwide and has become an urgent priority in South Africa as evidenced in the promulgated National Environmental Management Waste Act (2008). The most common waste disposal method in South Africa is by landfill, which is unacceptable. Local municipalities have made little progress towards waste minimisation.
The aim of this study was to present a solution to waste minimisation for the City of Tshwane Metropolitan Municipality (CTMM) by determining the feasibility of establishing composting facilities on landfill sites. One third of all municipal waste consists of green waste, which is compostable and can be converted on landfill sites. Nine municipal landfill sites were screened. The four most feasible sites were evaluated further by applying identified parameters that address physical, social and operational requirements. It is a possible to establish composting facilities on all four sites investigated, with Hatherley ranking as the most suited.
The findings of this study clearly provided the basic parameters and requirements for constructing a composting facility and practical procedures applicable within a South African context. The evaluation method used can be applied as a model to evaluate similar studies in other municipalities to aid them in the decision-making process for waste minimisation.
