Honeyprocessing is closely linked to water pollution due to the lack of a specificwastewater treatment. This work presents a sustainable and innovative solutionbased on two sequential bioprocesses using a real effluent from an Argentinehoney-exporting facility. In the first stage, the honey wastewater was enrichedwith a non-Saccharomyces yeast (Candidaethanolica), isolated and identified from the same effluent.

Honeyprocessing is closely linked to water pollution due to the lack of a specificwastewater treatment. This work presents a sustainable and innovative solutionbased on two sequential bioprocesses using a real effluent from an Argentinehoney-exporting facility. In the first stage, the honey wastewater was enrichedwith a non-Saccharomyces yeast (Candidaethanolica), isolated and identified from the same effluent. Yeasttreatment was carried out in a bioreactor, achieving nearly double theefficiency in total sugar removal compared to the control (native flora).Subsequent clarification with diatomaceous earth reduced optical density(91.6%) and COD (30.9%). In the second stage, secondary sewage effluent, wasadded to the clarified effluent and inoculated with Chlorella vulgaris under different culture conditions. The bestmicroalgae performance was observed under high light intensity and highinoculum concentration, reaching a fivefold increase in cell density, aspecific growth rate of 0.752 d⁻¹, and a doubling time of 0.921 d. Total sugarremoval in this stage was under 28%, while cumulative COD removal reached 90%in nine days under both lighting conditions. The synergistic use ofcomplementary microorganisms and different effluents enhances microalgal growthand supports to the overall sustainability of an integrated approach tomanaging all wastewater streams from honey production
