An Empirical Application of Structural Time based Modelling for the Efficient Management of Municipal Solid Waste

  • Yohannes Worku, Mammo Muchie


The aim of study was to explore factors that undermine efficiency in municipal waste management in the Tshwane region of South Africa by assessing and evaluating basic indicators of efficiency in municipal waste management in densely populated urban centers. The ability of businesses to optimally manage waste was measured by using criterion stipulated by Tchobanoglous, Theisen and Vigil (1993) in their structural time-based model. Compliance with municipal bylaws was assessed by using ISO 14032 standards as a benchmark. The study found that about 82% of businesses in the study managed their own waste optimally. Based on regression estimates obtained from ordered probit regression analysis, the management of waste by businesses was undermined by disregard to municipal bylaws by businesses, inability to enforce municipal bylaws, and the management of businesses by outside employees.
