Abstract：In order to alleviate environmental pressure and realize emission reduction and reuse of construction waste，measures should be taken at its origin，which requires the improvement of the management at the construction site. With the typical site of Chongqing city as an example，this paper uses the method of investigation and literature review to quantify the cost and benefit of on-site construction waste classification of construction enterprises，identifies the main obstacle to implement recognition of on-site classification，in order to promote the construction waste reduction，provide support and basis for promoting the on-site construction waste classification and resources development.
