Photobioreactor (PBR) - A new type of photobioreactor with low land use, high scalability for microalgae production

This solution is a new type of photobioreactor, with a low land use, high scalability and competitive costs.

The Photobioreactor overcomes the technical challenges slowing down the industrialization of microalgae cultivation, in particular in the feed, fuels, and plastics sectors. Indeed, raceway ponds are exposed to contaminations and poorly optimized, whereas more advanced PBRs are expensive and limited to small volumes. This solution allows to cultivate large volumes of microalgae in a controlled environment at a competitive price, which cannot be done with the current available technologies. It draws its advantage from the following features: SunOleo photobioreactors are simple microalgae cultivation tanks with immersed inflatable light wells, which bring sunlight up to 6m deep in the tanks. Hence, deeper reactors can be made, allowing mass cultivation of microalgae; Has a closed cultivation system, it ensures a better product quality than raceway ponds; its simple design and cheap light wells material allow economies of scale and production costs reduction.
