The use of fberglass-reinforced polymer (GFRP) as an alternative solution in strengthened concrete technology signifcantly has been increased recently. Fiberglass rebar (GFRP) took a stronger position in modern construction. This is due, on the one hand, to its high specifc strength (ratio of strength to specifc gravity) and on the other hand, too high corrosion resistance, frost resistance, and low thermal conductivity. Its non-corrosive nature has turned the attention of many researchers to make several studies on the diferent types of GFRP products. Insufcient resources for metal increase the requirement for renewable resources such as composites. However it is considered the environmental issues as a most signifcant problems which needs to study in every case, from this point of view despite all the GFRP advantages the environmental impacts of this material takes an important place to study, in this study the production stage of GFRP has been studied, in addition to better understand of the issue a comparison between steel rebars and GFRP was conducted, a signifcant environmental impact was seen in GFRP production process which needs to be considered for production of these materials.
