Physical, mechanical and environmental properties of fired clay bricks incorporated with palm oil mill waste

The growth of the oil palm industry in Malaysia has generated a significant amount of palm oil mill waste (POMW) causing waste disposal problems. Due to operational challenges and expensive operational cost, POMW is potentially incorporated into fired clay brick owing to high lignocellulosic charact...
