Both pathways are compatible with cyanobacterial WB but differ in energy demand, chemical requirements, and downstream processing. Life Cycle Assessment (LCA) was conducted using inventory data from process simulation and experimental extraction data. LCA results showed that PC extraction and purification were the most important contributors across all impact categories due to the large consumption of salts and ionic liquid (IL), respectively. Regarding biomass valorisation, AD presented advantages over HTL due to lower chemical and energy requirements. Based on these results, the influence of IL recovery was studied, and scenario 2 (IL recovery 90% + AD) was constructed and analysed from an LCA perspective. The comparison of LCA results for the analysed scenarios showed that increasing IL recovery by 15% (scenario 2) led to impact reductions up to 46% in the extraction step, achieving reductions up to 37% and 12% in the overall process compared to scenarios 1 A and 1B, respectively.

The results showed that lepidocrocite enhanced selenite removal over 120 days of operation, significantly reducing the average effluent concentration from 0.92 mg/L in the control group to 0.53 mg/L and increasing the removal rate. It also promoted the transformation of elemental selenium into selenide.
