Techno-economic assessment of bioactive compound recovery from potato peels with sequential hydrothermal extraction

The economic performance of Sequential Hydrothermal Extraction (SeqHTE) and subcritical water extraction (SWE) was evaluated in this study for recovering bioactive compounds from potato peels. analysis included the cost estimation additional units required extract purification, such as polysaccharide separation, glycoalkaloid isolation, two final product purification alternatives: filtration or adsorption. An annual plant capacity 4540 tonne dry peel an on-stream factor 300 days were considered a basis study. tecno-economic showed that overall capital investments costs manufacture SeqHTE 1.5 to 2 times greater than SWE. However, two-stage system compared favorably with one-stage approach terms of. unit production costs. For adsorption, lowest price polyphenol estimated be $0.43/kg $67.00/kg, respectively. In contrast, SWE these $0.74/kg $70.00/kg, results also although adsorption notably more costly (5–7 higher), it provided significantly refined presumably superior quality product. Moreover, sensitivity operating costs, recovery potential generate co-products most important factors affect performance. Therefore, because allows complete utilization biomass possibly valuable bioactives; process may provide economical alternative valorizing
