Data are presented on tar and char yields from newsprint pyrolysed at temperatures between 300 and 385ยฐC and at pressures ranging from below 0.1 kPa to 93 kPa. A one parameter model is developed to describe the effect of ambient pressure on tar yield. Both untreated and iy/, HCI washed newsprint are
