Abstract: With the acceleration of the urbanization process and the proposal of the zero-waste city construction target, the recycling of construction and demolition waste (C&D waste) has become an important topic. Among all the types of C&D waste, the decoration waste needs to be more properly disposed because of the dispersed sources and complex components. Starting from the characteristics of decoration waste, the composition and particle size distribution of decoration waste were analyzed. According to the situation of complex components, the current situation of collection and transportation and the typical process route of “two-stage crushing + multi-stage sorting”were introduced. The optimization of treatment process in practical engineering application were summarized, the problems existing in the decoration waste recycling industry and feasible countermeasures were discussed, which provided references for the development of the decoration waste recycling industry.

Key words: decoration waste, recycling, recycled aggregate, pollution control
