Abstract

Nutrient recycling Agricultural waste to profit Microalgae valorization Circular bioeconomy Sustainability
The possibility of using microalgae to assimilate nitrogen from agricultural anaerobic digestion effluents (ADE) not only has environmental benefits but also can result in making profit from ADE by converting microalgae to value added products. Here, a techno economic model was developed to study the possibility of producing oil and amino acid concentrate products from microalgae grown on ADE. The results show that it would be possible to produce 14 L biostimulant (amino acid concentrate), 198 g refined oil, and 57 g omega 3 isolate from 1 m3 ADE using microalgae with possible production cost of 0.9 – 2.1 AUD L−1, 86 – 120 AUD kg−1, and 700 – 730 AUD kg−1 respectively depending on the scale. The profitability results at the scale of 500 to 3,000 m3 d−1 ADE capacity indicate that the production of biostimulant, refined oil, and omega 3 isolate products from wastewater grown microalgae can lead to 4 – 15, 6 – 9, and 5 AUD m−3 net profit respectively.
