Incineration reduces sewage sludge volume, but management of the resulting ash is an important environmental concern. A laboratory incubation study and greenhouse pot experiments with lettuce (Lactuca sativa L.) and corn (Zea mays L.) were conducted to examine the potential for recycling elements in...
Sewage sludge incineration ash (SSIA), the by-product of waste-to-energy (WtE) incineration of sewage sludge, is a major municipal waste containing phosphorus-fertilizing nutrients. For the first time, we investigated the novel application of SSIA as a soilless plant-growing medium with built-in...
Sewagesludge ash(SSA) produced from incineration at 700 °C for 3 h, contains 50.6% SiO2, 12.8% Al2O3,and 7.21% Fe2O3(Table 1).SSAcontainedamorphousSiO2particles with diameters between 0.1 and 1 μm (Pan & Tseng, 2001). However, the chemical properties of SSA are expected to be hig...

pollution by the scattering of ashes at the time of damping at damping site by making them non-breakable pellets by a procedure in which incineration ashes are halved according to specific basicity and subjected to respective predetermined treatments when sewage sludge incineration ashes are treated. ...
Mono-incineration of sewage sludge produces sewage sludge ash (SSA) from which phosphorus can be recovered. With this plant, the company will ensure the reliable disposal of sewage sludge and enable the recovery of valuable phosphorus. It will burn sludges from about 80 municipalities in North...
Therefore, Hong Kong has established a 2000 tonnes day−1 sewage sludge incineration facility (T-Park) in 2015. A considerable amount of sewage sludge ash (ISSA, which amounts to about 10% of the dewatered sewage sludge incinerated) from the sewage sludge incinerator is generated. The ...
The incineration of sewage sludge produces sewage sludge ash, which has achieved commercial viability in the manufacturing of construction products, thanks to its use in cement manufacturing as an alternative fuel. However, the implementation of construction products incorporating sewage sludge ash is stil...
treatment, following items were clarified in this paper: 1) It is found that the sludge dehydration was improved in proportion to the addition of sludge incinerator ash; 2) But, generally sludge incinerator ash itself includes many fine particles with high specific gravity, which may plug ...
During sewage sludge incineration phosphorus (P) is retained in the ash in a form not directly available to plants. As P is a sparse resource, it is important to develop techniques for recovery of P from incinerated sewage sludge ashes (ISSA). Heavy metals are concentrated in ISSA and separa...
