Abstract—Mechanical properties of natural rubber composites filled with waste materials including waste tire rubber, rice husk ash and starch sludge were comparatively investigated along with commercial reinforcing fillers, carbon black and silica, using maleated natural rubber (MNR) or silane (Si69) as a coupling agent. It was found that rubber with rice husk ash gave higher tensile strength than ones with starch sludge and waste tire. Rice husk ash gave similar strength to silica and using MNR was better than Si69. Waste fillers gave higher compression set than carbon black and crumb rubber yielded better abrasive resistance than carbon black and silica. It was also seen that mechanical properties decreased with increasing starch sludge loading. The optimum loading is 10 phr starch sludge with 5 phr MNR. These experimental results showed that for certain applications, waste materials could be used as alternative filler in the rubber production

Index Terms—Rice husk, rubber composite, starch sludge, waste tire.
