Abstract
There is a demand to remove CO2 from thermal plants to abate global warming. At the same time authorities demand treating wastewater to remove nitrogen and phosphorus and also to produce food. By combining algae farming at a power plant and using nutrients from the wastewater, actions to meet all these demands can be combined to a win-win situation. In this paper we make estimates what the dimensions and design criteria there would be for such an integrated system. The size of the algae farm will be significant. If placed in the sea, this may be feasible, but then storms must be considered. If we place in lakes, it is more competition for other uses that causes a problem. Combining with also greenhouses may be a possible solution. The biomass produced can be used directly as food or be processed by, e.g., fermentation to produce chemicals and methane (biogas).
期刊介绍:
Advances in Biochemical Engineering/Biotechnology reviews actual trends in modern biotechnology. Its aim is to cover all aspects of this interdisciplinary technology where knowledge, methods and expertise are required for chemistry, biochemistry, microbiology, genetics, chemical engineering and computer science. Special volumes are dedicated to selected topics which focus on new biotechnological products and new processes for their synthesis and purification. They give the state-of-the-art of a topic in a comprehensive way thus being a valuable source for the next 3 - 5 years. It also discusses new discoveries and applications.
