Graphic paper The simulation of the graphic paper recycling loop for newsprint was investigated more or less simultaneously during the end of the 1990’s in three different places on various scales in Europe. Multiple recycling experiments were performed by a team of researchers from SCA 1 in Sundsvall on the laboratory scale, at the Institut
