Summary 45 Seaweed in closed systems (SICS) Hart, P. ât (Koers & Vaart B.V) and J. Schipper (Hortimare) InnovationNetwork Report No. 11.2.259, Utrecht, The Netherlands, April 2011. Seaweed is a potential source of green raw materials. They are used for human consumption, contain speciï¬c thickening agents such as alginates and carrageenans, and can be applied as growth-promoting fertilizers, in animal feed and for the cultivation of shellï¬sh (abalones). In addition, extracts from seaweed are used in cosmetics and pharmaceutical products and seaweeds also constitute a possible source of biofuels. Seaweed can possibly also serve as a protein platform for catering to the steadily growing demand for ï¬sh protein and soy protein. Though the Netherlands has a good reputation in oï¬shore and hydraulic engineering as well as in seed cultivation and improvement, the knowledge of cultivating and harvesting seaweed is very limited. With the advent of wind farms in the North Sea and the commercial exploitation of the continental shelf, the opportunities for cultivating seaweed are now also being explored. Both extensive and intensive cultivation systems as used in agriculture and horticulture are being considered. Certain applications of seaweed require more controlled cultivation conditions. This is the case with speciï¬c plant substances, nutritional factors and with the propagation of seaweed for large-scale cultivation. Wherever the value of the cultivated seaweed increases, and hence the need for harvest security and risk control, closed systems are probably the best approach. Pagina 54
