Building Industry has been recognized to be the largest single consumer of finite natural resources. Rapid depletion of natural resources and consequential rise in their price has to be absorbed largely by the industry itself. High competition in the free market does not permit the transfer of resultant increase in the cost of production to consumers. Industry is, therefore, hard pressed to exploit all the engineering, technological and managerial skills to reduce manufacturing costs. Judicious selection of resources and their efficient utilization should surely help a lot in achieving the defined objective through mitigation or at least substantial reduction of wastages of all kinds. Waste is visualized as any unnecessary input to or any undesirable output from a system. Waste can occur in variety of forms and at number of stages in an engineering industry. Besides the scrap produced and undesirable outcomes of the processes, there are other forms of waste such as using more expensive materials than required, consuming excessive energy, using old technology, keeping higher inventories, under-utilization of machinery and manpower and so on. Concerted and sustained efforts alone using appropriate technology at every stage of production activity can check waste generation. In the given situation, waste management program gains importance. For an effective management approach, it is prudent to deal with waste at a system level. Despite the industry being alive to the prevailing dismal situation it is continuing with the old practices or have marginally improved. It is largely due to lack of awareness and familiarity on the part of the industry, with the tools and techniques of waste management and their application in the real life situations. Accordingly, industry is not in a position to precisely work out the amount of waste being generated and effectively mitigates it. This paper studies the utilization of alumina waste and silica waste for geopolymer production. The study makes the reuse of aluminum hydroxide waste (Al-waste) for geopolymers.
