The environmental concern brought the idea of sustainable development. From the conception of the rule of consideration of sustainability in activities, all sectors, including civil construction, had to adapt their management, implementation of processes, choice of materials and their disposal. The sustainability criteria, the idea of being environmentally correct even brought the development of new materials from recycled construction waste. Among the types of waste that are most produced and discarded in civil construction, there is 2 concrete. In view of the above, the general objective of this article was to investigate the possibility of recycling and reusing concrete waste and the validity of this practice regarding environmental and economic aspects in the civil construction industry. Through literature review research, with collection of bibliographic and secondary data, it was concluded that sustainability is a new paradigm in civil construction. It was seen that recycling and reuse of waste brought changes in management, processes and techniques as well as materials. It was understood that concrete is one of the main residues of civil construction. This can be recycled in fresh or solid state, being reused for different purposes, contributing to an economic and environmental aspect, as it represents less waste and use of natural resources.
