Abstract

Globally, solid waste (SW) generation has continued to increase exponentially with its statistic that stood at ~2 billion tonnes (BTs) in 2016 and has been predicted to reach ~3 and ~3.5 BTs by 2030 and 2050, respectively. In the developing countries, the upsurge is the same and the factors responsible for the continuous increase are alike. These factors include rapid population and economic growth, industrialization, changes in consumption pattern and urbanization. The most startling thing is that many of the treatment methods used are unsustainable, since public health and the environment are impacted negatively. In South Africa, for instance, the most common municipal SW treatment method is landfilling but many of the landfill facilities are almost reaching their full capacities and there are also unavailable land spaces for new disposal facilities. Therefore, this study intends to present summary of different SW management methods like opening burning, open dumping (either to the sea or uncultivated lands), incineration, composting, anaerobic digestion, and recycling. Additionally, this highlight anticipates outlining current technologies, challenges encountered, and proposes corrective mitigation procedure.
