Eco-friendly method using live algae for natural greening
A recently granted patent (Publication Number: US11963485B2) discloses a natural invasion promoting method that involves spraying a material containing live algae on a soil surface. The live algae, dried at a temperature of 60°C or less and pulverized, is applied in an amount of 30 g/m2 or less based on its dry weight. The method includes breeding the live algae and utilizing a tacky substance secreted on the algae's surface or a catching structure made of the algae to catch flying seeds or spores, promoting greening on the soil surface. The catching structure is described as a three-dimensional network formed by entwining filamentous or randomly overlapping algae structures.
Furthermore, the patent claims include variations of the method, such as incorporating a killed algae product along with the live algae in the spraying material. The killed algae product, obtained through a specific treatment, contains protein and other components like carbohydrates, lipids, and ash. Additionally, the spraying material may also contain a tackifier to enhance its effectiveness. The method aims to facilitate natural invasion by allowing flying seeds or spores to flow onto the soil and be captured by the tacky substance or the three-dimensional catching network structure. Overall, the patent outlines a comprehensive approach to promoting greening and natural invasion using live algae and related products in a controlled manner.
