Solid waste management is being done in several ways but there is a need for an effective and a creative way that aims to bring sustainable development in the construction industry. Existing methods of waste management and disposal like the land filling is ultimately polluting the soil and ground water. The need for manufactured aggregates is to promote the 3 R’s (Reduce, Reuse & Recycle) and to achieve a sustainable development. Manufactured aggregates may reduce environmental strain by minimizing over exploitation and indiscriminative use of natural aggregates which we get from the mining, quarrying and blasting activities. Waste is not a waste unless you waste it. This paper focuses on the synthesis of an ingenious construction material (Coarse aggregates) from the various industrial wastes which are ceramic materials, lathe waste and plastics (Low density & Medium density polyethylene) along with slag (fly ash/ Ground Granulated Blast furnace Slag) in definite proportions. Coarse aggregate synthesised through this process have both advantages and disadvantages when compared to the natural aggregates. Various tests for aggregate which are specified in the IS 2386 does not seem applicable as these artificial aggregates undergo elastic or plastic deformation.
