ABSTRACT

Due to rapid human population in the world, high rate of consumption and urbanisation has been the result, which has led to massive increase in Municipal Solid Waste (MSW) generation. Various areas of review in this study reveals that MSW is becoming a global concern primarily in developing countries where the high cost of acquiring waste treatment infrastructures have diverted the attention of stake holders to cheap alternatives. Furthermore, review on China as a developing country revealed landfill/open dumping as a major waste management practice which does not only have the potentials of causing regional impacts such as acidification, but can also result in global impacts such as global warming which the entire world is desperately working towards minimising. Also, review on Germany as advanced country revealed recycling as the primary method of waste management practice which utilises the principles of waste management hierarchy and thus, regulations and policies on MSW handling in Germany led to zero waste disposal at landfills. Moreover, various MSW treatment technologies were assessed in terms of capital cost, effectiveness with regards to energy production and environmental impacts. The result of the assessment showed that some waste treatment technologies (incineration and pyrolysis) though cost effective, may require further development to improve the current standard to meet the waste management policies and directives. Contrary, some wastes treatment technologies such as anaerobic digestion is not versatile in terms of handling all kinds of waste, but has been proven very effective in the treatment of organic waste with minimal cost and emission potentials. However, the findings revealed that conventional gasification technology requires low capital cost with minimal toxicity in the emissions, but requires further developments in the waste treatment versatility. The study also reveals that landfill requires more developments than every other waste treatment technologies due to the drawbacks associated with the process. Finally, plasma arc gasification technology though cost intensive and not widely used, proves to be a very good option with exceptional qualities over other MSW treatment technologies.
