Bioorganic novel approaches for food processing waste water treatment and valorisation: Lupanine case study (Biorg4WasteWaterVal+) aims
Food processing industry uses a large volume of fresh water to deliver safe food for humanity, which is obtained from public water providers or ground and spring water sources. The resulting brackish wastewater is often disposed of in public sewers or using different suboptimal solutions. The food processing industry is comprised of several factories of small/medium size, calling for a modular technological solution able to be quickly implemented at the companies site.
In the project Bioorganic novel approaches for food processing waste water treatment and valorisation: Lupanine case study (Biorg4WasteWaterVal+), novel separation processes using low energy and chemicals at low cost will be developed based on novel membrane processes and adsorbers capable of purifying the water for in-situ recycling at zero cost for the company. A far reaching concept is suggested in which alkaloids are isolated and converted into building blocks of value for pharmaceutical and chemical industries, compensating for water detoxification costs. New biological and chemical tools will be developed for conversion of alkaloids into such added value compounds. Lupanine is used as a particular example to illustrate this case.
The Case study: Lupin bean production:
- The global production of lupin beans is ca 930 000 tons (2009);
- Lupin beans are rich in toxic alkaloids, which need to be removed before being used as human or animal food. Requires aprox. 14 m3 fresh water / ton of salted beans
Part of a larger Problem:
The food processing industry uses a large volume of fresh water to deliver safe food.
Examples in m3 of water/ton of food:
- 54-77 (green beans)
- 11.5-22.5 (sugar beet )
- 3.6-22 (peach and pears)
Industry organization and needs:
- Factories of small/medium factories size;
- Need of modular technological solutions of quick implemented at the companies’ site;
- Competitive wastewater treatment with in-site recycling.
APPROACH TAKEN AND INNOVATION SOUGHT:
Novel business models with 3rd parties able to:
- water detoxification in-situ techs;
- produce and commercialize the added value products.
A compact modular water detoxification process:
- First micro/ultra membrane stage to retain carbon rich fraction for energy production;
- Second nanofiltration membrane stage to reuse 80% of the water to recycle in food processing deliver a highly concentrated solution of alkaloids
Improved sustainability and downstream separations:
- Biogas production for energy sustainability and waste minimization;
- New DNA-aptamer and MIPs for alkaloids separations;
- New diastereomeric resolution of alkaloids.
New routes for process sustainability and alkaloid valorization:
- Alkaloid resistant microrganisms for biogas production, alkaline mineralization or conversion;
- Non degradative bioconversion of alkaloid into new structural motifs for organic synthetic transformations;
- Chemical transformation into added value compounds.
