Abstract

Life cycle assessment (LCA) applied to engineered nanomaterials (ENMs) faces many challenges, one of the most relevant being the lack of databases providing nano-specific data. LCA for ENMs applied in environmental remediation is still in its early stages as indicated not only by the scarce number of published works but also by the fact that most of them correspond to water treatment in laboratory scale processes. However, the analysis of the literature evidenced that there is genuine interest in the scientific community to incorporate a rigorous and formal analysis of the environmental impact of ENMs for water treatment. It is worth mentioning that some works have used LCA as a prospective tool, positioning LCA as a powerful instrument for process optimization in terms of their environmental impact before scale-up.
