Clean production in stone cutting industries

International Journal of Environment and Waste Management (IJEWM), Vol. 1, No. 2/3, 2007

Abstract: The stone cutting industry uses high volume of water for cooling purposes and produces large volume of sludge. The disposal of both the wastewater and the sludge to a solid waste disposal site is costly and environmentally unacceptable. Wastewater and sludge from stone cutting industries in Jordan has been characterised and reused in various processes. Stone cutting industries can be modified to convert them into zero discharging industries by recycling the wastewater. The sludge can be used for producing bricks when it is in the slurry phase thus eliminating the need for water for producing bricks and the need for sludge disposal.
