![]() On the other hand, Electronic waste contains many toxics such as heavy metals, including lead, cadmium, mercury, barium, beryllium, plastics, including Polychlorinated Biphenyls (PCBs), Poly Vinyl Chloride (PVC), Polystyrene (PS) etc. Maharashtra ranks first followed by Tamil Nadu, Andra Pradesh, Uttar Pradesh, West Bengal, Delhi, Karnataka, Gujarat, Madhya Pradesh and Punjab in the list of E-waste generating states in India. Ten states generate 70% of the total E-waste generated in India. Among top ten cities generating E waste Mumbai ranks first followed by Delhi, Bangalore, Chennai, Kolkotta, Ahmedabad, Hyderabad, Pune, Surat and Nagpur. Sixty five cities in India generate more than 60% of total E-waste generated in India. This geometrically progressed to 8,00,000 tonnes as per 2012 statistics. It has been studied statistically that the total quantity of E-waste accumulated in India as on 2080 tonnes. Characterization of this waste stream is of paramount importance for developing a cost effective and environmental recycling system. Worldwide, nearly the same amount as all plastic packaging, but it is much more hazardous. Electronic waste (e- waste) now makes up 5% of all municipal solid waste In developing countries, it ranges from 0.01% to 1% of the total municipal solid waste generation. ![]() In developed countries, previously, it was about 1% of total solid waste generation and it had grown to 2% by 2010. The e-waste inventory based on this obsolescence rate in India shows an increase every year. The increase of electrical and electronic products, consumption rates and higher obsolescence rate leads to higher generation of e- waste. E-waste is one of the fastest growing waste streams in the world. It also includes used electronics which are destined for reuse, resale, salvage, recycling, or disposal. Keywords – E-waste Compressive strength Split tensile Flexural strength High impact polystyrene M25 concreteĮlectronic waste includes discarded computers, office electronic equipment, printer, scanner etc. This study also ensures that reusing E- waste as above gives a good approach to reduce cost of materials and also provide a solution for disposal of solid waste problems posed by E-waste. In the above investigation, it was found that use of E- waste as partial replacement for aggregates results in the formation of concrete which has lesser weight than that of conventional concrete. The optimum dosage of E-waste to be added in M25 grade of concrete was determined. The compressive strength, split tensile strength and flexural strength of concrete were found for various percentage replacements of E-waste in concrete and compared with that of the control mix. The mix design for M25 grade concrete was done by IS code method. The replacement of coarse aggregate by E-waste was in the range of 10%, 15%, and 20%. The type of E-waste selected was high impact polystyrene which is non- degradable and also impermeable. In this work, effect of partial replacement of coarse aggregate by E-waste in concrete was studied. ![]() E-waste may be used as one such alternative for coarse aggregate. Due to increase in cost of normal coarse aggregate it has forced the civil engineers to find out suitable alternatives to it. For solving the disposal of large amount of E-waste material, reuse of E-waste in concrete industry is considered as one of the most feasible application.
