The final stage, and ultimate goal of this research, is to develop a one-point process where optimal extraction of precious materials can be obtained from sewage sludge. The recovery processes may include physical, chemical and biological applications and the overall cost will depend on the efficiency and complexity of each recovery method.
Jan 30, 2009· Joint research conducted in 2007 by Nagano prefecture and the Japan Sewage Works Agency found that the concentration of gold in the ash was comparable to that of a high-grade ore. But because the cost of extracting the gold outweighed the potential profit, the operator continued treating the ash as an industrial waste material.

Jan 18, 2017· Viral sewage metagenomics is a novel field of study used for surveillance, epidemiological studies, and evaluation of waste water treatment efficiency. In raw sewage human waste is mixed with , industrial and drainage water, and virus particles are, therefore, only found in low concentrations. This necessitates a step of sample concentration to allow for sensitive virus detection.
