        abstract = {The growing demand for sustainable construction materials has increased interest in replacing conventional fired clay bricks with low-carbon masonry units produced from industrial and municipal waste streams. Municipal solid waste incineration residues, especially bottom ash and related ash fractions, contain silica, calcium, and alumina-bearing phases that can participate in alkali activation when properly processed, offering a potential route for converting problematic waste into useful construction products. This paper presents a research-style framework for the synthesis of eco-friendly alkali-activated bricks using municipal incinerator ash as a primary precursor, supported by supplementary aluminosilicate sources and alkaline activators. The proposed system emphasizes pre-treatment, mix optimization, moulding, ambient or moderate thermal curing, and evaluation through compressive strength, water absorption, density, microstructure, and leaching behaviour. Prior studies show that municipal incinerator ash-based alkali-activated systems can achieve compressive strengths ranging from low values in untreated ash systems to around 50 MPa or more when combined with reactive materials such as fly ash, GGBS, or metakaolin and when activator composition is optimized. The paper also highlights critical design challenges, including metallic aluminium-induced porosity, soluble salts, and heavy metal immobilization, and discusses practical mitigation methods such as washing, grinding, blending, and controlled curing. The proposed methodology is intended to support laboratory-scale development of sustainable bricks suitable for non-load-bearing and potentially structural applications subject to code compliance and environmental safety verification.},
