In this work, there were analyzed the properties of particleboards produced with two types of recycled paper (newspaper and offset) and slash pine wood particles (Pinus elliottii Engelm.). The paper was introduced into the mattress in two forms: strands and after hammer milling, in different proportions: 0, 20, 40, 60 and 100% of ovendry weight of the particles. The adhesive used was 10% tannin-formaldehyde (100:10 parts by weight). The experiment was set according to a factorial model, with three replications. The tests were conducted following ASTM D1037 (1995). Boards produced both with offset and newspaper strand inclusions showed tendency to blow at press opening. The inclusion of paper caused decrease in the properties, in such degree that boards did not meet commerce standards DIN 68761 (1)-1961, (3)-1971 and ANSI A 208.1 (1987). Water absorption after 24 hours, internal bond and screw whitdraw were the properties most affected. In general, the use of newspaper was more encouraging than offset paper.
