Rose distillation wastewater (RDW), the major by-product of rose processing, still contains a significant load of polyphenolic compounds. This organic burden poses a significant environmental threat for RDW disposal, while, on the other hand, it still contains valuable compounds that could be valorized in the circular economy framework. This study has investigated the possibility of utilizing RDW in various concentrations (10%, 25%, 100% <i>v</i>/<i>v</i>) as a circular tomato growth biostimulant, addressing the existing research gap in the field of circular RDW valorizatAntioxidants (Basel, Switzerland)Rose Oil Distillation Wastewater: By-Products of Essential Oil Extraction as Circular Biostimulants for Tomato Growth.PMC12561105451-03-136/2025-03/200134, 451-03-137/2025-03/200134, 451-03-137/2025-03/200125, 451-03-136/2025-03/200125, 003075720 2024 09418 003 000 000 001 04 004, 003076284 2024 09418 003 000 000 001/1Lesjak MZivanovic NSimin NDanilov IVlajkov VLjubojevic MDujkovic TGrahovac JfalseRose Oil Distillation Wastewater: By-Products of Essential Oil Extraction as Circular Biostimulants for Tomato Growth.Rose processing into essentials oil is one of the major sectors providing inputs for cosmetics and health/food supplements industry, generating significant amount of wastewater if applying the steam distillation approach.
