Hospitals, health care, and research centres produce significant amounts of biomedical waste, which are hazardous to human health and the natural habitat. The scale of biomedical waste production has enormously escalated in recent decades. Incineration is an ideal solution to reduce the volume of waste while destroying dangerous microorganisms and minimizing the uncontrolled disposal of heavy metals. Incineration produces a residual solid material called biomedical waste ash (BMWA). Incinerated biomedical waste can reduce its environmental impact by being utilized in the construction sector. Numerous studies have shown the detrimental effects of BMWA addition to concrete, which impedes the use of BMWA in the construction industry. This manuscript reviewed the promising utilization of BMWA as a supplemental cementitious material in concrete. The focus is on presenting recent advancements in understanding the impact of the physical, chemical, and microstructural characteristics of BMWA on the properties of blended concrete. The effects of BMWA on the material properties, consistency, setting time, workability, strength, sorptivity, and chloride penetration of blended concrete are critically compared and analyzed. The leaching behaviour of BMWA was found to meet the standard leaching limits set by the US EPA (United States Environmental Protection Agency). The utilization of BMWA in volumes up to 5% for the cement replacement and 15% for the sand replacement can produce high-strength and durable concrete for greener and sustainable applications of BMWA in the construction sector. In addition, the review recommends a detailed framework for the utilization of BMWA to achieve cleaner production in the construction sector.
