“…The reference method reduced the alkaloid content to 0.66 ± 0.00 g/kg DM after 58 h, consuming 66 L of water/kg dry seed. This result is similar to those of the samples treated with 1% NaCl and 0.5% citric acid for 57 h and 40 L water/kg dry seed, as well as with 1% citric acid for 45 h and 35 L water/kg dry seed; however, the experimental method saved time and water, thus reducing the volume of toxic effluents to be disposed of, or treated to recover lupanine, a building block in the synthesis of pharmaceutical molecules (Esteves et al, 2020). Furthermore, the seeds debittered with 1% citric acid for 57 h and 40 L/kg of water attained an even lower alkaloid concentration (0.37 ± 0.06 g/kg DM).…”

“…Previous results showed that with this solvent, it was possible to achieve the same lupanine recovery efficiency (92−98)% and purity (77%), by SE of lupin bean-enriched NF wastewaters, using less solvent when compared to MTBE. 18 The adsorption isotherm for lupanine on MIP-1 is shown in Figure 7. The correlation coefficient for the Freundlich model (0.9323) is similar to the one of the Langmuir model (0.9302) (Table S3).…”

Lupanine is an alkaloid used in the pharma industry as a building block or precursor in the synthesis of sparteine and also explored for drug synthesis in the pharma industry as a chiral selector. This alkaloid is found in lupin bean processing wastewaters originated from the debittering process to make these beans edible. In this work, a computational chemistry approach was taken to design molecularly imprinted polymers (MIPs) selecting itaconic acid, a biobased building block, as a functional monomer that can provide higher affinities for lupanine. MIP-1 was prepared using lupanine as the template, itaconic acid as a functional monomer, and ethylene glycol dimethacrylate as a cross-linker by bulk polymerization. Lupanine was concentrated from lupin bean wastewater by nanofiltration, extracted with ethyl acetate, and purified using the synthesized MIP. MIP-1 was able to selectively recognize lupanine and improve the purity of lupanine from 78 to 88%, with 82% recovery of the alkaloid. These results show the potential application of this strategy to render the industrial process more sustainable.

“…It removes a large amount of multivalent inorganic salts and small organic molecules while operating at a moderate pressure; the moderate operating pressure makes the separation process consume little energy and is cost-effective [43]. Therefore, it has been applied to various industrial sectors for wastewater treatment, e.g., water recycling during fishmeal, lupin bean, and textile processing [44][45][46]. A few researchers explored NF for PSWW treatment by using standalone NF or combining NF with UF.…”

Poultry slaughterhouses produce a large amount of wastewater, which is usually treated by conventional methods. The traditional techniques face some challenges, especially the incapability of recovering valuable nutrients and reusing the treated water. Therefore, membrane technology has been widely adopted by researchers due to its enormous advantages over conventional methods. Pressure-driven membranes, such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO), have been studied to purify poultry slaughterhouse wastewater (PSWW) as a standalone process or an integrated process with other procedures. Membrane technology showed excellent performance by providing high efficiency for pollutant removal and the recovery of water and valuable products. It may remove approximately all the pollutants from PSWW and purify the water to the required level for discharge to the environment and even reuse for industrial poultry processing purposes while being economically efficient. This article comprehensively reviews the treatment and reuse of PSWW with MF, UF, NF, and RO. Most valuable nutrients can be recovered by UF, and high-quality water for reuse in poultry processing can be produced by RO from PSWW. The incredible performance of membrane technology indicates that membrane technology is an alternative approach for treating PSWW.
