1 application of paper making industry wastes in construction materials

 the continuous generation of industrial waste and the environmental problems it causes and on the other hand, the increasing refusal of communities to have landfills, as well as the increased pressure from environmental agencies to require proper waste management, make it necessary to focus on alternative rational cost methods. most researches in the area of solid waste management has centered on the conventional alternatives of landfilling, burning or incineration, and land application. the discussion includes some paper industry waste management alternatives including several which have recently received considerable attention and considers grit, dregs, ash, and fiber. so in this paper the application of such wastes in construction materials such as brick, ceramic, cement clinker, bituminous mixes and etc., whose properties and composition permit the incorporation of these elements in their manufacture was investigated, and also at the end the advantages and disadvantages of some methods were discussed.
