    Development and characterization Of thermal insulation boards from Tanneries waste
    (UMT, Lhr, 2019) MUHAMMAD IJAZ
    Pakistan has a reputable Tanning industry with abundant supply of leather products. Pakistan Bureau of statistics ranked it as second largest export-oriented industry after textiles. It is fast growing industry in terms of qualitative, economy and export. The major challenge faced by this industry is the disposal of solid and liquid waste; generated during tanning process. The solid wastes include skin trimmings, fleshing, buffing dust and chrome shavings. The main constituent of this waste is protein, if not treated properly causes hazardous pollution to the environment. Reutilization of this leather waste was taken as an opportunity to clean the cities environment. Literature studies have shown that these products can be used in development of other useful products. Tanning Industries of Kasur which are famous for raw leather products has been be taken as a case study for sample collection. In the next stage, experimentation were performed on this waste material. Leather waste was mixed with plaster of paris to develop Insulation boards. At initial level, eight to ten boards were prepared by varying the quantities of waste and binding material. Then different physio-chemical tests were like thermal conductivity, mechanical strength and FTIR were performed on all the boards. The board which have maximum thermal conductivity and maximum strength were selected as final product.
