The disposal of sludge from sewage water treatment is a big issue for wastewater plants in Malaysia. While studies show that the volume of sludge is expected to rise, disposal options are limited due to stricter environmental regulations including a ban on burying sludge in soil due to its high heavy metal content that could cause adverse impacts to the environment. Meanwhile, the construction sector is seeking economic and ecological cement replacement materials in order to meet an increasing demand for concrete.
