“…The existence of heavy metal in S/S treatment can influence the cementation process. The result is supported by previous study stated by [3], found that the different concentration of heavy metal in the S/S treatment will influence the result of solidified sludge treated. The influence of IPA to stabilize the sludge obviously reduces the heavy metal concentration in the sludge after the treatment, but the result indicates an increase in concentration of Copper (Cu).…”

“…As according by [1] in their study, it is expected concerning 30% of the assembly within the ceramic industry generate a waste whereas nowadays, the waste is not being recycled or reusable. In step with [2,3], the ceramic industry releases a big quantity of heavy metals. Costly and not appropriate treatment because of new options to legitimately deal with and deal with the expanding of ceramic sludge should be any investigated.…”

This research explored the potential to use IPA as a binder for the treatment of industrial waste sludge. Within the study, Incinerated Paper Ash (IPA) was used together Ordinary Portland Cement (OPC), a main material employed in solidification/stabilization (S/S) methodology to treated industrial ceramic sludge. The issues created by OPC in sustain the surroundings and cost force the new material must replace OPC as binder within the treatment methodology. The impact of the various IPA compositions within the system has been examined. The Unconfined Compressive Strength (UCS) and Toxicity Characteristic Leaching Procedure (TCLP) were used to assess the viability of IPA in sludge treatment once 28 days. The great result of compressive strength and decrease in heavy metals shows the potential of IPA in OPC replacement.

“…OPC and WPSA have 50.67% and 63.0% of CaO respectively. A larger amount of Ca in the form of CaO and Ca(OH)2 in the solid treated WTS resulted in a reduction of heavy metals leaching [11]. From all the metals concentration obtained, it can be stated that WPSA was successfully stabilized the WTS.…”

“…During the implementation of S/S technique using OPC, water in the sludge reacts chemically with it to form hydrated silicates and aluminates (C-S-H) gel resulting in a solid monolithic mass. The development of C-S-H gel assists in reducing the amount of Ca(OH)2 that tends to lower down the strength of end products [11]. Indeed, a binder from industrial waste materials also offers effective performance in treating the sludge.…”

Water treatment sludge (WTS) has been a major global problem and dealing with it remains a challenge for scientists and engineers. WTS is expected to increase annually parallel to the continuous increase in population [1]. Every year, 2 million tons of WTS is produced by water operators in Malaysia to cope with the increase population number of 16, 800/year [2], [3]. WTS can be highly toxic for environment and human health. WTS has a tendency to cause soil pollution when it disposed on the land or even from acidic rain. The exposure tends to cause the breaking down soils and releasing heavy metals into streams, lakes, rivers and groundwater [4]. Metals in untreated WTS tends to accumulate although the metals are usually found at low level of concentration. Due to the hazardous effects that can cause to environmental and human health problems prior to land disposal, issues of WTS needs to be treated before dump should be considered. One of sludge treatment technique is Solidification/Stabilisation (S/S) technique. The application of S/S technique to treat WTS is somehow limited as WTS is always considered to be non-toxic. Thus, incineration and landfilling are alternative sludge treatment practiced till today [5]. S/S technique is simple in operation and should be implemented Abstract: Waste Paper Sludge Ash (WPSA) was used as stabilizer binder to treat water treatment sludge (WTS). This study was conducted to treat WTS by using WPSA in Solidification/Stabilisation (S/S) technique. WPSA was utilized at 10%, 20%, 30%, 40% and 50% to treat 200g WTS at binder-to-sludge (B/Sd) ratio 1:1. The control sample was 100% Ordinary Portland Cement (OPC). The compressive strength and leaching test on WTS treated with WPSA at specified percentage were performed. The compressive strength was conducted on sample cured at age 1, 3, 7 and 28 days. The leaching test was conducted only on sample cured at age 28 days. The minimum target compressive strength was 0.34 MPa as accordance to USEPA. The maximum metals acceptance criteria as stipulated by Kualiti Alam were 1.0, 5.0, 100.0, 100.0 and 5.0 mg/L for cadmium (Cd), lead (Pb), nickel (Ni), copper (Cu) and chromium (Cr) respectively. Results showed that the compressive strength decreases with increasing WPSA content but exceeded the minimum target strength. The compressive strength increases with respect to curing days. The optimum content of WPSA to treat WTS was 50% (W5). The compressive strength of W5 with high WPSA content was the first exceeded the minimum compressive strength. The concentration of metals decreases with respect to percentage of WPSA added.

“…Furthermore, waste sludge generated by ceramic effluent treatment plants can be effectively utilized as a supplementary cementitious material (SCM) [9]. This can effectively enhance concrete strength [10,11], reduce water bleeding, and improve cohesion in the fresh phase [10]. Therefore, the addition of CWP to concrete mixtures can improve concrete durability [12].…”

Global carbon dioxide emissions can be attributed to Portland cement production; thus, an alternative cementitious system is essential to reduce cement demand. Ceramic waste powder (CWP), which contains high proportions of silica and alumina, has emerged as a promising alternative because of its chemical composition. This review discusses the potential of CWP as an alternative cementitious system and its effects on the physical, mechanical, and durability properties of cementitious systems. The findings revealed that the utilization of CWP in cementitious systems has positive effects on their physical, mechanical, and durability properties owing to the chemical composition of CWP, which can act as a filler material or contribute to the pozzolanic reaction. A pozzolanic reaction occurs between the silica and alumina in the CWP and calcium hydroxide in the cement, resulting in the production of additional cementitious materials such as calcium silicate hydrates and calcium aluminate hydrates. These additional materials can improve the strength and durability of cementitious systems. Various studies have demonstrated that CWP can be effectively used as a partial replacement for cement in cementitious systems. This can reduce the carbon footprint of construction activities by reducing the demand for Portland cement. However, the optimal amount and particle size of CWP have not been fully determined, and further research is required to optimize its use in cementitious systems. In addition, the technical and economic challenges associated with the use of CWP in construction must be further investigated to ensure its effective implementation.
