Processes for the Production of Seaweed Liquid Fertiliser from Brown Seaweed

An integrated method is developed to utilize to a maximum extent the fresh biomass of seaweeds such as Kappaphycus alvarezii.

The fresh seaweed as harvested from sea coast by a method of crushing and filtering instead of drying so as obtain sap and a solid residue as two useful products simultaneously and cost-effectively to produce a seaweed liquid fertilizer which are proven to be a promising low cost bio fertilizer (foliar spray as well as soil applications) and residue processed for recovery of cellulosic and carbon materials which may be used for suitable applications.

• Low cost bio fertilizer that can affordable even by marginal farmers.
• The residue generated while producing liquid fertilizer can be used as a feedstock for making a commercially important products such as cellulose, carbon materials, for desired applications etc.
