Water re-use in the context of the circular economy and sustainability

Abstract

The purpose of this article is to shed light on the consolidation of water re-use in the circular economy in Brazil, highlighting experiences in Spain, as a conventional strategic resource that will contribute to the effecti-veness of sustainability. This study is divided into two moments: the first deals with current water re-use practices in Brazil in the circular economy; the second addresses Spain's contribution to wastewater re-use as a contributing factor for more effective sustainability. It is concluded that water re-use is a reference and a useful model in Brazil, although not widely applied. The po-tential for re-use is an indisputable fact, but its consolidation as a conventional strategic resource is a challenge that demands a coordinated, rigid approach to the planning of future actions by all parties involved. Spain’s experience in this sector is very advanced; the actors involved contribute to putting the process into practice, and there is a structured normative and administrative apparatus, while Brazil lacks specific legislation. The methodology was inductive logic based on bibliographic and documentary research
