• bioplastics
• fertilizers
• energy

Microalgae and macro algae (seaweed) are currently under great interest as a source of biofuels, (fine) biochemical building blocks and food. The growth and multiplication rate of algae is high, and algae can be easily refined. That makes algae one of the most attractive sources for biomass production. Algae (both microalgae and seaweed) have an advantage over land-based biomass because they can be cultivated in open water and therefore do not compete with agricultural areas intended for food breeding. Algae, like other biomasses for growth, need nutrients and CO2. Seaweeds extract these building materials from the surrounding water, microalgae that are grown in closed systems (PBR: photobioreactors) receive nutrients and CO2. It is possible to obtain nutrients from communal or industrial waste water flows and CO2 from waste gases from the industry. This makes the cultivation of microalgae financially and environmentally attractive. The condition is that micro algae PBR is realized in the vicinity of WWTPs and / or industrial areas in order to reduce high logistical costs. Biomark Biotechnology BV is currently in the final phase of a study into the feasibility of a floating system that combines the cultivation of seaweed with the cultivation of microalgae. The microalgae are grown in closed floating PBRs that are anchored on the seabed. To the anchoring, ropes are connected to which seaweed can be grown. The yield of the biomass per square meter of this combined system can thus be 3.4 to 3.8 times higher than when only micro algae or seaweed is cultivated. The system can also provide benefits for nature values for coastal areas by increasing the oxygen content through oxygen introduction, forming artificial fish hatchery. This means that this system can deliver benefits in several areas: the yield compared to conventional systems is higher; the system does not compete with valuable building or agricultural land; energy consumption is lower because less (circular) pump capacity is necessary due to wave movement of the sea.
