Therefore it is of critical value to find use cases for it. Unfortunately most of our Sewage sludge is buried underground or burned in incineration plants, caused by the contamination of industry waste and also private waste. Contamination also caused the
ban of sewage sludge to be used as a fertilizer on agricultural fields. Therefore I began to look for possible uses for this abundant matieral. Thanks to the wastewater
treatment plant in Bruchsal I was able to get hold of sewage sludge
(SSA). This material consists of all solid matter in our wastewater.
Thanks to the wastewater incineration plant Stuttgart I was able to get hold of
incinerated sewage sludge ash (SSIA). SSIA is the remnants of the incineration
of raw sewage sludge. Results are a sintered ceramic material made from SSIA
and SSA and a lightweight aggregate made from SSIA and Limestone.
The Ceramics are sintered at 1100 Degrees and form a stonelike material with a
red color. Shapes were created by loading the material in a ceramic 3D Printer
and extruding. The Lightweight aggregate on the other hand is easily castable,
light and solid. Suitable for quick molds and building materials. The bathroom
collection consists of a toilet seat, a toilet brush holder, a soap dish and other
gadgets. They bring the waste back to its origins, questioning if this material is
more than just waste and revealing a invisible byproduct of our daily lifes.
