Disposing sludge left over from treating sewage water is a major challenge for wastewater plants in Malaysia. While studies show that the volume of sludge is expected to rise, disposal options are limited due to strict environmental regulations, including a ban on burying sludge in soil due to its high heavy metal content. Meanwhile, the construction sector seeks economic and ecological cement replacement materials in order to meet an increasing demand for concrete.
