Waste writing paper samples were collected from some used practical record books from chemistry laboratories, Department of Chemistry, Bago University. Waste writing papers were deinked by using hydrogen peroxide and sodium laurly sulphate and then treated with 5% NaOH. The resultant samples were coded as untreated waste writing papers (UWP) and NaOH treated waste writing papers (TWP).The physicochemical properties of UWP and TWP (moisture, ash, PH ) were determined by conventional methods.doi:10.5281/zenodo.3923288 fatcat:odjz2nnc2ff23lai6tcz2yhw3u
