Abstract

<p><font face="Arial">'Waste to wealth' is a motto coiled up recently by the Malaysian govemment to encourage resource recovery from various waste materials generated from industrial and agricultural activities. The introduction of this concept and subsequent implementation is due to the fact that many of the waste generated may still contain materials which can be transformed into value added products directly or indirectly. The emphasis is now on the types of waste generated in huge amount. One such waste is sludge generated in waste water treatment plants.In this work the concept of 'waste to wealth' is put into implementation where the content of this waste was first analyzed to determine how wealth can be generated. From the analysis, it was found that big portion of the dry sludge contain alumina, calcium oxides and ferum oxide. These materials are commonly used for making clay based materials such as brick, floor tiles and roof tiles. Therefore, fired clay samples were produced using this waste. The samples were firstly evaluated for their engineering characteristics where up to an addition of 20% wt of waste, the samples met the minimum criteria as an engineering building material in terms of strength and water absorption. Economic benefits that one can expect from this project were briefly discussed.The paper will also further explore other routes to create more wealth from this waste.</font></p>
