Malaysia has too much sewage sludge and not enough concrete, a problem which naturally prompted an "aha!" moment among researchers. By burning and drying wet sewage sludge cake and then grinding and sieving the dry cake to produce Domestic Waste Sludge Powder (DWSP), the Malaysian researchers are attempting to create an additive that can be mixed with cement to produce concrete.
So far, they've found a mixture of between 3% to 15% DWSP in cement produces fairly strong concrete, although the higher percentage of DWSP, the less strong the concrete becomes. Variables abound: according to this report, higher incineration temperatures can produce better DWSP, and the more DWSP in the concrete, the higher the water absorption.

Love it, now we finally find where Ballskin can be useful.
Much respect, Julia, for the name of this article. It's perfect.
This didn't even need an article behind it. The title was enough - I love it.
