Lots of construction and demolition waste are produced in the course of construction activities which has a serious impact on surroundings, if it’s not properly handled. This has become a serious issue in the Ghanaian Construction industry. Other issues of waste management on construction sites has caused lots of failures like increasing the cost of project and the loss of materials that are valuable Based on that, the research aim at exploring the usage of construction and demolishing debris in the Ghanaian Construction Industry. Three major objectives were derived from this aim to help achieving it. The objective was, to identify the usage of construction debris in the Ghanaian Construction Industry, to determine challenges of usage of debris in the Ghanaian Construction Industry, to identify critical success factors for utilization of construction debris in the Ghanaian Construction Industry. Quantitative research approach was used for the study, alongside with a purposive and snowball sampling technique. Out of the 50 questionnaires administer, 31 were retrieved. The variables were analyzed using means score, descriptive statistics and a reliability of the scale checked using Cronbach Alpha coefficient. All variables identified were ranked in order of importance and usage. The revealed that, the Ghanaian construction industry make use of construction debris as filling material for landfill, land reclamation and many others. However, some challenges were identified as hindering factors to the proper utilization of these waste materials. Strategies through the study were identified as mitigating factors to help increase the rate of their usage.
