The rapid growth of the coffee industry is accompanied by a staggering increase in the amount of agriculture waste produced. In coffee producing countries, coffee wastes constitute a source of severe contamination and a serious environmental problem. In this study, the investigation on the possibility to utilize the coffee waste (CW) incorporated into the fired clay brick was carried out. The main purpose of this study is to determine the physical, mechanical properties and leachab~lityte st of bricks incorporated with different percentages of CW. In this methodology, control brick (CB) and three different percentages of coffee waste brick (CWB) (I%3% ,a nd 5%) were manufactured and fired at 1050°C. Physical and mechanical properties including shrinkage, density and compressive strength were reported and discussed. Additionally, leaching of heavy metals from manufactured clay brick was tested by using TCLP. The results reported that with the incorporation of CW, the shrinkage increased linearly but still comply with a minimum standard below 8% and good quality of brick was manufactured. Meanwhile, the results showed that density value decreased up to 30% from the normal brlck w~th increased percentages of CW. The decreased compressive strength value of all the manufactured brick is still complied with a minimum standard. On the other hand, heavy metals concentration leach out from different percentages of coffee waste brick is not exceed~ngth e limit of 5 mglL allowed by USEPA. As a conclusion, the incorporation of CW into fired clay brick gives some advantages to the brick properties and also provides an alternative solution on disposing of the CW. In addition, the CW could also be a potential of low-cost waste additive for the production of brick
