Item Formulation of Shoe Polish from Wax and Used Water SAchets(Addis Ababa University, 2017-06) Worku, Betrework; Woldeyes, Belay (Professor)The conversion of Used Water Sachets to Shoe Polish was investigated. Used water sachets were pyrolyzed at various temperatures to obtain polyethylene (sachet) wax. Polyethylene wax with good melting point, yield was produced between 100 - 200˚C, used to produce the shoe polish. Three different formulated shoe polishes were prepared from polyethylene wax and the properties of the three samples were compared with the standard polish (Kiwi). The density, melting point, physical testing of shoe polish, and viscosity of the polish formulated using different percentage of used polyethylene wax, compared favorably with standard commercial polish. The effects of temperature and pyrolysis time on the properties of polyethylene wax produced from used water sachets were investigated. Used water sachets were pyrolysed at temperatures between 100 -200 ℃ for 30-60 min. The effect of temperature and pyrolysis time is significant on the yield and melting point of sachet wax produced. The sachet wax obtained had the melting point of 76 ℃ while the yield of sachet wax was 35.4 %.Waste sachets pyrolysed at 100 °C for 45 minutes produced sachet wax from used water sachets with yield of 35.4 %, good melting point & viscosity.
