Resumo: | The project aimed to carry out the techno-economic modeling of the heterotrophic microalgae bioreactors application in the poultry and swine abattoirs and processing wastewater treatment and possible exploitation of bioproducts from biomass generated in the process. The project focus was directed to the techno-economic modeling of bioprocesses following: (i) agroindustrial wastewater treatment and integral biomass production (ii) obtaining of bulk oil and lipid extracted algal (LEA) as feedstock for biodiesel conversion process and protein production (iii) obtaining of microalgal carotenoid-rich oleoresin solubilized in soybean oil. The results indicated that the agroindustrial wastewater treatment costs and production of microalgal biomass were USD 2.66 per cubic meter and USD 30 per ton of dried biomass respectively. The obtaining of bulk oil and LEA had a production cost of approx. USD 386.5 and 70.4 per ton. Finally, the oleoresin produced had an estimated production cost in USD 146.9 per kilogram. The results evidenced that the techno-economic modeling of the heterotrophic microalgae bioreactors application are an alternative to substantially minimize the production costs, giving economic sustainability to the agroindustry of poultry and swine processing. |
