A suite of technologies for mass production of microalgae on waste streams and converting the harvested algal biomass into drop-in fuels, animal/fish feed and other high value byproducts have been developed and the summary and preliminary conclusions reached including: 1) Development of a fast screening strategy for local bio-prospecting robust algal stains which adapted well in different types of wastewater resources including municipal wastewater (CMW) and swine manure wastewater (DSM) and the results showed the high lipid productivity (77.5-94.8 mgL-1d-1) and high growth rate (0.43-0.53 d-1) were obtained for the selected most promising strains belonging to Chlorella, Heynigia, Hindakia, Micractinium, and Scenedesmus, etc; 2) A low-capital, low maintenance cost and highly scalable multi-layer based hybrid cultivation systems for year-round production of algae in northern climate was developed; 3) An integrated swine manure-based algal platform was developed for sequential biofuel and omega-3 contained algal biomass production especially for animal/fish feed uses. 4) A novel fungi-assisted bio-flocculation technique for low-cost and highly efficient microalgal cells harvesting is developed and its further application was discussed. 5) Development of an integrated biorefining concept and system process for water recycling and nutrient reuse: Including combing fungi-assisted harvesting system for water recycling and utilization the nutrients of aqueous phase derived from the pyrolysis and hydrothermal liquefaction of the algae biomass for nutrients reuse. 6) Life cycle analysis for our unique wastewater-based process for environmental factors during biofuel and biobased chemical production will also be presented. Specific details will be presented and discussed in this presentation.
