Turning dead marine algae into a powdered animal feed product is an excellent example of full-circle sustainability. Grinding, mixing and drying of these algae results in a completely natural calcinated seaweed, containing lots of different minerals. This calcinated seaweed is enriched with magnesium oxide and suitable as an organic livestock feed in powder form. The resulting product works as an acid buffer, regulating the acid in a cow's stomach to aid digestion and – in addition to its health benefits – it also reduces the production of methane.
An important requirement for the mixing process of calcinated seaweed and magnesium oxide is to minimize the amount of dust produced by the powdered end product, because this will cause problems for farmers, resulting in unnecessary product loss of the feed during the dosing process in silos, and also for the cattle because the fine powder can cause irritation in the nose/lungs.
