RESUMO

The use of the residues generated by the paper industry as a geotechnical material, has become common practice in recent years. This practice is due to two important aspects: the economical and environmental aspects. The paper industry generates a significant amount of residue and with the increase of the costs related to the disposal of this material, there is a growing need to recycle. The objective of this work is to present the geotechnical properties of the paper residue generated by the Rigesa paper Industry in Valinhos, São Paulo. The study of this kind of residue intends to contribute to the reduction of the cost in the final disposal of the residue for the paper industry and, on the other hand, to offer an economic alternative for covering systems. This residue is generated from the sludges of the system of residuary water treatment of the industry. The residue is the secondary sludges of the process of the treatment in the recycling station where cardboard boxes are manufactured. The material presents a high organic content, a high initial water content and a high compressibility. This is presented in details through tests carried out with the residue. However, it should be pointed out that results obtained involve aspects related to the methodology of the test for this material. In this way the present work intends to contribute to the re-structuring of the conventional tests. The tests performed were: Limit of Atterberg, Specify Gravity, Grain Size Distribution, Consolidation, Permeability, Direct Shear, and the soil water Storage curve.
