Waste to Value: Energy positive targeted resource recovery from sludge (2016–2019)
Sludge management is a major issue for water utilities, incurring substantial costs. The latter is caused by the poor dewaterability of sludge resulting in high moisture contents. This project aims to develop an innovative, cost-effective and sustainable technology and the underpinning science to enable complete dewatering of sludge. The only solid residue is inorganic ash, which enables targeted recovery of valuable resources from the ash such as coagulants, phosphate, and metals. The outcomes will provide strong support to the water utilities in achieving sustainable sludge management and potentially brings large economic, environmental and social benefits, to the water utilities.
