Accordingly, a huge amount of incineration ash (so-called paper sludge ash, PS-ash in short in the present study) is discharged. Some studies have attempted the recycling of PS-ash; for instance, hydrothermal solidification to produce building materials, solidification materials of soft ground, coagulants for dredging, etc. [27,28,29].

2.2 Waste Paper Sludge Ash (WPSA) The wastepaper sludge ash (WPSA) is a main additive to stabilize the soft soil was used in this study. This white WPSA was in a powder form is a waste product from the combustion of waste paper in paper recycling factories was obtained from Malaysia Newsprint Industries in Pahang, Malaysia.
Paper sludge ash (PSA) was obtained from Aylesford Newsprint Ltd., a major UK newsprint . 97 . manufacturer producing 400,000 tonnes per year of recycled newsprint from 500,000 tonnes of waste ...
Sludge refers to the solid waste produced after sewage treatment. Unreasonable disposal of sludge can cause environmental pollution. Nonetheless, the sludge contains large amounts of silica-aluminate, which has …
The decline eased as waste paper sludge ash production increased. Because waste paper sludge and ash particles absorbed more water than cement, the workability of concrete mix was reduced. Waste paper sludge ash made up 2.5% of the concrete mixture with the highest level of slump. Fig. 2 illustrates how slump varies depending on the presence of ...
The feasibility of using a low-cost super hydrophobic powder as water-resisting admixture or water-repellent surface coating for concrete has been investigated. The powder was produced from paper sludge ash (PSA), a by-product from the manufacture of recycled paper.

However, petroleum sludge ash still poses a major environmental challenge due to high levels of heavy metals and other contaminants. Former research works have shown that heavy metals and toxic compounds present in petroleum sludge ash can be entrapped in geopolymer medium, whilst improving its compressive strength .
It was found that paper sludge tends to be a fibrous admixture, bottom ash tends to replace sand to a certain extent, and fly ash is a replacement for cement. The cement industry is mugging up several dares, like bankrupting fossil fuel reserves, lack of raw materials, and an endlessly rising appeal for cement and concrete [14], [15] .
