Beyond aquaculture proper, seaweed cultivation could also function as a general instrument for circular resource management (Seghetta et al., 2016), treatment of waste water produced by land-based farming and municipal treatment plants (Neveux et al., 2016), heavy metal biosorption (He & Chen, 2014) and recolonization of artificial reefs (Fig. 1).

The grinding operations remove a certain amount of material or grind a certain number of parts before dressing. For example, after 10 grinding passes on the workpiece, the wheel could be dressed to re-establish the wheel form, wheel face sharpness or both. A continuous dress process constantly dresses the grinding wheel during the grinding cycle.

The aim is to provide a dynamic model of the biogenic carbon cycle with a view to carbon neutrality of future macroalgae-based biorefinery systems.
