In this digital era, usage of electric and electronic devices has become the need of people. Evolution of technology triggers the adoption of new devices over old and discarded appliances turned into the electronic wastes also termed as e-waste/s. E-waste from any source has become a major concern to the society. The disposal of these wastes into the landfills causes many hazardous impacts to the ecosystem. As a promising solution construction industry can utilize the e-wastes effectively. The wastes may be used either as fine filler or aggregates in concrete and bituminous based constructions efficiently. Usage of waste/s conserves the natural resources also. Present study magnifies the scenario of application of electronic wastes in different forms i.e., plastic, metal etc. in bituminous and concrete based mixtures. A critical review has been carried the effects of electronic wastes in concrete and bituminous mixes and findings confirm the praxis of electronic wastes is possible within certain limits.

The purpose of putting up this paper is to analyze the case of using e-waste enhancers in the reinforcement of concrete pavements which must have a positive impact in the promotion of sustainability in constructions. The increased stream of electronic products which reach the end of their lifecycle is a serious global problem since millions of tons of electronic waste are produced every year. It is a rabid problem. Professionally speaking, e-waste is improperly dumped and it holds dangerous chemical compounding so it has negative impacts on the environment and health, especially containing lead mercury, cadmium. These substances can and do get into the soil, the air and the water and there is therefore high pollution and health effects. Thus, it becomes necessary to consider different means to address the problem of e-waste disposal, and one such method is recycling through incorporation of concrete.The direct impact of not following proper e-waste disposal causes pollution and therefore, it’s very important to manage this waste adequately. Thus, the use of e-waste can help to dispose of the problem, and at the same time, enhance construction material performance by using its properties. From the study described in the detailed review, it is observed that the e-waste can be used in the enhancement of the mechanical properties of concrete and subsequently increase the environmental performance of concrete without any negative effects.In the present study the aim is to identify the research done in the past in an effort to identify the different approaches used in the disposal of e-waste in concrete as well as to measure the performance. This assessment was done systematically, in which the analysis of different materials in e-waste and their role in a concrete mix like plastics, metal, glass and ceramics was considered. Safe management of wastes from electronic products has become a significant area of concern with e waste concrete being among the most popular and appropriate methods of dealing with wastes while at the same time improving the performance of concrete.This research triangulates on the renewed future of e- waste concrete as an innovative construction material that can help in the reduction of waste material as well as the conservation of resources.
