This study presents the design of a novel sustainable ECC that simultaneously achieves high strength and ductility, incorporating hybrid fibres, nanocellulose (NC), and high volumes of fly ash and silica fume. A novel approach utilising the hybrid application of Taguchi- Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) methods is adopted for the design, enabling systematic and precise adjustment of mix constituents and leading to optimized performance. The standard Taguchi orthogonal array, consisting of four factors, i.e. fly ash to silica fume ratio, water-to-binder ratio, fibre proportions, and nanocellulose dosage, was used to design the mix. The optimum combination of these constituents was determined to maximize five key response parameters: compressive strength, elastic modulus, flexural strength, tensile strength, and ultimate tensile strain. Results indicated that fly ash to silica fume ratio of 1:0.2, a water to binder ratio of 0.22, 1.5 % polyethylene +0.75 % steel fibre by volume, and 0.25 % NC by weight represent the optimal mix design. This mix achieved a compressive strength of 71 MPa, an elastic modulus of 30 GPa, a flexural strength of 17 MPa, an ultimate tensile strength of 4 MPa, and an ultimate tensile strain of 3 %. The optimal design was further validated by experimental results, which showed that the optimized mix outperformed all other mixes in all indices.

Overspray waste from high velocity oxy fuel (HVOF) spraying of a WC-20Cr<sub>3</sub>C<sub>2</sub>-7Ni powder from an industrial spray shop was systematically collected and characterized for morphology, particle size distribution, and phase composition.

The resulting coatings were evaluated for microstructure, phase constitution, hardness and wear performance, and their characteristics were compared with coatings produced from virgin powder deposited via HVOF and HVAF. The results were noted to be extremely encouraging, with HVAF coatings using HVOF overspray outperforming HVOF coatings with virgin powder feedstock, making a strong case to investigate further possibilities to gainfully utilize thermal spray waste from varied sources. Considering that tungsten and chromium are critical raw materials, with tungsten bearing a particularly high carbon footprint, this study also quantitatively assesses the sustainability benefits of reusing the overspray powder.
