    Nutrient pollution is one of the most challenging environmental problems worldwide. Excess phosphate in water causes eutrophication, where algae bloom occurs and deteriorates water quality due to decreasing oxygen levels, affecting aquatic life. Marsh clam shell has potential as an adsorbent material due to its plentiful supply and good absorption capability towards phosphate. The aim of this study is to investigate phosphate removal by using raw marsh clam shell as the adsorbent in different concentrations of aqueous solution (5, 10, 15, 20, and 25 mg/L) in batch experiments. The mass of adsorbent was kept constant at 2 g and the volume of aqueous solution was fixed at 100 mL. Phosphate removal for the solution with 25 mg/L concentration was the highest, 5.8% compared to other concentrations. The experimental data obtained were compared to the theoretical data. The experimental data fitted well with the pseudo-second-order kinetic model (R2 = 1) and Freundlich isotherm model (R2 = 0.9982), suggesting that phosphate adsorption onto raw marsh clam shell is a chemical and multilayer sorption. In conclusion, the application of raw marsh clam shells for phosphate removal from aqueous solutions has potential as a low-cost and effective future wastewater treatment alternative for domestic and industrial wastewater treatment systems.

    Sustainable Development Goals (SDG) 9 calls for resilient infrastructure, promote inclusive and sustainable industrialisation and foster innovation. Echoing this vision, construction industries have prioritised resilient structure and sustainable design while optimising economic and wealth growth. The use of steel fibre (SteFib) as scattered reinforcement in building design and construction had been explored. SteFib has been designed as reinforcement in the structural components of the building namely, raft foundation, floor and roof slabs, wall panel and column. Prototype of an Industrialised Building System (IBS) with two (2) bedrooms, one (1) living area and linked to a small kitchen was constructed using hook ended SteFib, 60 mm long and 0.7 mm in diameter mixed in grade 40 concrete. The prototype has successfully proven that the SteFib is able to stand as fully reinforced structure through this tiny home project. The structural performance analysed and verified using Autodesk Robot Structural Analysis. The analysis results show that steel fibre house has higher stress, forces and moment compared with normal concrete house.

    The excessive amount of biowaste in landfills has resulted in significant environmental contamination problems.To achieve environmental sustainability and protection of our ecosystem, this study aims to evaluate the adsorption performance of saltwater clamshell (SWCS) and zeolite in reducing the water pollutants expressed as Total Nitrogen (TN), Total Phosphorus (TP), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD) and total suspended solids (TSS) from river water.The collected natural river water sample was first circulated through the adsorbents in a fabricated model for five consecutive days and each of the water parameters was then tested every day according to APHA standards.The result showed that SWCS had a higher adsorption capacity than zeolite.The adsorption capacity of the SWCS for TSS, TP, TN, COD, and BOD was 6.967 mg/g, 0.310 mg/g, 1.357 mg/g, 3.5 mg/g, and 1.667 mg/g respectively.Whilst zeolite had capacities of 2.51 mg/g, 0.032 mg/g, 0.6377 mg/g, 0.7 mg/g, and 0.4 mg/g respectively.Based on the isotherm analysis, BOD(Zeolite), TSS(Zeolite), COD(Zeolite), TN(Zeolite), BOD(SWCS), TP(SWCS), and TSS(SWCS) showed higher regression (R 2 > 0.95) in Langmuir isotherm, while TP(Zeolite), TN(SWCS), and COD(SWCS) had higher regression (R 2 > 0.88) in Freundlich isotherm.Additionally, BOD (Zeolite), TP (Zeolite), TSS (Zeolite), and TN(SWCS) demonstrated a higher correlation with the Pseudo-First-Order model.On the other hand, COD(Zeolite), TN(Zeolite), BOD(SWCS), COD(SWCS), TP(SWCS), and TSS(SWCS) fitted well into the Pseudo-second-order model.Overall, this study proved that SWCS and zeolite are viable alternatives for removing organic and nutrient pollutants.

    Rapid urbanisation in Malaysia has accelerated water pollution in rivers and other water sources, causing irreversible harm to the ecosystem. In view of that, this study aimed to work on using fly ash to address certain heavy metal components (chromium (Cr), copper (Cu), nickel (Ni), and zinc (Zn)) present in polluted water. The experiment employed three batches of fly ash. Two batches were treated with sodium hydroxide (NaOH-FA) and hydrochloric acid (HCl-FA), whereas one batch was left untreated (UFA). The three batches of adsorbents were examined by using a jar test after solutions containing 100 mg/L of Cr, Cu, Ni, and Zn ions were made. The results of various contact periods demonstrated that the fly ash had variable capacities for metal ion adsorption. The maximum adsorption of UFA was 79.958%(Cr), 80.814%(Cu), 81.580%(Ni), and 82.742%(Zn) while HCl-FA was adsorbing 77.148%(Cr), 82.546%(Cu), 78.896%(Ni), and 78.248%(Zn). NaOH-FA in this study was found to adsorb 80.828%(Cr), 79.230%(Cu), 81.692%(Ni), and 77.394%(Zn). Further to this, it was revealed that the Temkin Isotherm model was best fitted with the highest R² values (> 0.98). The negative value of the slope, B indicated that the adsorption is an endothermic process which leans towards physical adsorption. In conclusion, this study demonstrated the successful application of fly ash in water or wastewater treatment of metal ions.
