A new recycling system by using paper debris and polymer has been developed for high water-content mud such as bed materials in the river and lake, and construction sludge. The new recycling system proposed in this study consists of two steps. In the first step, the paper debris are added for controlling water content of mud and strengthening the bonding force between mud clusters. In the second step, polymer materials are added to increase the bonding force of mud particles in the cluster. By using this system, 200- 500% water-content mud has been modified to landfill materials by 20-30 minutes mixing process.<BR>The unconfined and triaxial compression tests were carried out to examine the strength of the recycled soils. It was confirmed through the tests that the failure strain and residual strength of the recycled soils produced by the new system are much larger than those of recycled soils produced by the conventional method. Furthermore, the transformation coefficient of the recycled soils is close to the one of the ordinary soils. Therefore, it can be concluded that the recycled soils produced by the new system are much more suitable for landfill materials than the recycled soils produced by the conventional method.
