Dried sewage sludge could be recycled by adding it to cement
to make concrete, scientists in Malaysia have discovered. Sludge is what’s left
after treating sewage water. Sludge disposal options are limited in Malaysia
due to strict environmental norms, including a ban in burying it in soil due to
the high heavy metal content. According to the researchers from University
technology MARA, while there is a “potential” to use dried sludge to make
concrete, more research is needed to yield a better quality product.
