The recovery rate of construction materials is only 5% in China, which will lead to environmental and economic problems. Researchers from other countries have recognized the potential of building information modelling (BIM) in optimizing construction material recycling. However, previous research did not take the whole life cycle into consideration and was not practical enough. In this research, a questionnaire was conducted to find out how construction waste is disposed of in construction projects. Then, the existing research results were analyzed to find out how to apply BIM in the whole-life-cycle disposal of construction materials. According to the results of the questionnaire, landfill is the most common way to dispose of construction materials in China; besides this, almost no construction projects use BIM in material recycling. Hence, a BIM-based dynamic recycling model is proposed. Information management of materials, demolition planning, and BIM were all combined in this model for the purpose of optimizing the application of BIM, thus developing a waste material disposal system to achieve higher recovery rates and sustainability. More positive measures should be taken to deal with the problem of construction waste; if not, more environmental and economic problems will follow.
