Abstract: With the development of waste classification， the disposal of urban bulky waste has become the focus of attention of solid waste treatment region. Based on the bulky waste treatment spot of Yunan environmental park in Shenzhen， the composition and treatment cost of the collected bulky waste were analyzed. The results revealed that bulky waste that entered the treatment facility mainly consist of tables， chairs， beds and mattresses， the handling capacity ranged from large to small was chair， mattress， bed and table. The composition of chair wastes from May to June was quite different to that from July to November. The main components of disassembled bulky waste were wood， bed net， sponge， metal and residue. Among them， the residue which was difficult to be separated was the main factor that restricted the utilization of bulky waste. By upgrading the process to reduce the proportion of residues and improving the quality of disassembled materials， the resource utilization rate of bulky waste could be effectively improved， and the yields were expected to rise by more than 60%.
