However, the cost to recycle the demolition wastes becomes higher if they were very mixed in the first place. The result is low recovery rate. In addition, the recycled materials from very mixed demolition wastes frequently prevent them from becoming an ingredient for a higher value recycling product. Therefore, it is imperative to execute onsite source separation by employing proper steps. The objective of this research is to develop an appraisal system for the assessment of green demolition. Literature reviews about construction steps and waste handling for building demolition. The four major categories identified are reduce and recycling, energy conservation, environmental protection and safety precaution. Fuzzy Delphi method are first employed in this study to identify the major categories and their corresponding items for assessing the “greenness” of a demolition project. AHP (Analytical Hierarchy Process) method is then employed to determine the weighting of major categories as well as the sub items in each category. As a result, this study proposes an appraisal rating system to assess the “greenness” of a demolition project. With the appraisal system, the recovery rate of building demolished wastes can be increased and improving the Building Demolition quality.
