This investigation implemented a mixed-method approach, which integrated qualitative and quantitative data collection methodologies. The totals of 70 questionnaires were distributed to professionals working in construction industry to collect primary data. Secondary data were obtained from a variety of published and unpublished documents. The reliability of the research was verified by calculating Cronbach's Alpha coefficient, and the data were analyzed using Microsoft Excel and SPSS software. The findings of the study revealed that sustainable construction waste management practices are acknowledged; however, their implementation is inconsistent. The main challenges identified are a lack of technical skills, insufficient market infrastructure for sustainable technologies, inadequate government policies, and limited stakeholders’ awareness. The study also revealed the critical role of construction professionals in promoting sustainability standards, influencing market practices, and providing training, even though the mentioned challenges frequently hinder these projects. In conclusion, the research emphasizes the necessity of targeted interventions to overcome the challenges to sustainable construction waste management in Tarcha Town. The following are suggested: augmenting training programs for construction professionals, strengthening government policies, improving access to sustainable technologies, and increasing stakeholders’ awareness. The construction industry in this region must implement these measures to achieve its overall sustainability objectives. The implementation of these recommendations will make a substantial contribution to the reduction of environmental impacts associated with construction activities. It will also contribute to a more sustainable future for the building construction industry in Tarcha Town.
