This paper analyzed some unsolved problems for materials-cycle sustainable society, with special reference to the gap between the supply and the demand of recyclable materials. Both relatively higher price of recycled resources to virgin resources and difficulties in expanding the use of recycled materials are the major reasons of the gap. The pressure of global competition for the low cost production is also an unfavorable factor to the labor-intensive recycling activity. This paper also analyzed the issue of construction waste, especially residuals generated from urban reconstruction. This paper concludes that city and land use planning in nationwide should be reformed taking into consideration the reduction and recycling of construction waste.
