| Abstract |
Human activities produce waste. In autotrophic mode, microalgae consume these waste materials, as growth nutrients, along with sunlight to create more biomass and O-2. This process is known as photosynthesis, and microalgae are the fastest photosynthetic organism on the planet. Moreover, they are not land-based and do not compete for arable land. The algae themselves are full of useful products. This paper demonstrates at near commercial scale that nutrients in waste streams can be recovered and recycled in a circular economy by algae production. The downstream process for algae harvesting and refinement is also demonstrated at scale via a bio-refinery approach with close to 100% mass efficiency. In this way, valuable products can be obtained from recycled materials resulting in a cost-effective process. Thus, algae have great potential to bio-remediate waste materials and create value, which has significant environmental benefits. |
