Municipal solid waste incineration fly ash is generated in a significant amount; it is classified as hazardous waste in Taiwan. In order to reduce the volume of treated fly ash, a sintering technology can be considered. However, a traditional sintering consumes too much energy because of the limit of heat transfer. Hence, a microwave process which can provide quick, uniform, and selective heati...

According to the IPCC (Intergovernmental Panel on Climate Change) guidelines, when calculating CO2 emissions, CO2 emissions from biomass should be excluded from the total amount of CO2 emissions and should be separately reported due to their “carbon neutrality”. Sewage sludge is one of the representative biomass fuels. It is mixed with fossil fuels to achieve greenhouse gas reduction or is used...

According to the IPCC guidelines, CO2 emissions from biomass should be excluded from the entire amount of CO2 emissions when calculating CO2 emissions and should be separately reported due to the “carbon neutrality.” Sewage sludge is one of the representative biomass fuels. And it is mixed with fossil fuels in terms of greenhouse gas reduction or is used as fuel to replace fossil fuels by itsel...

In addition to the positive effects on the physical, chemical and biological soil properties of the application of sewage sludge into the soil, there is often an increase of both organic and inorganic pollutants in the soil. One of the most popular organic xenobiotics frequently present in sewage sludge are polycyclic aromatic hydrocarbons. The aim of this study is to determine possibilities fo...

Utilization of sewage sludge on land is an appealing sludge disposal method. The reasons are not just because of the environmental and economic constraints associated with other disposal methods such as incineration and landfilling, but also because the sludge is beneficial both as a soil conditioner and as a fertilizer [1,2]. However, the major limitation with land application of sewage sludge...

In this article, glaze with different colorants was applied to tile specimens manufactured by incinerated sewage sludge ash (ISSA) and clay. Improvements using different amounts of colorants, and glaze components and concentrations on tile bodies were investigated. Four different proportions of clay (by weight ratio) were replaced by ISSA. Tiles of size 12 cm x 6 cm x 1 cm were made and left in...
