Seaweeds and their downstream processed products
Application Uses

India being agriculture country, there is considerable demand for developing low cost bio fertilizer that can affordable even by marginal farmers for enhancement of crop yields & quality. 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. It is tested for enhancing the crop yield & quality. LSPB and its solid formulations shows excellent enhancement in crop yields from 13 to 28%.

Salient Technical Features

The fresh/dry seaweed biomass is liquefied to produce a seaweed liquid fertilizer which 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. Raw material (brown seaweeds) used are abundant in nature and easy to harvest.

Business scope & opportunity

India import large quantity of seaweed fertilizer that involves high foreign exchange exchequer (tentatively estimated at 800-1000 crore). The technology has already been transferred to 10 industries for commercial production in India & revenue opportunity potential of licensee (in the near term) - ~₹20 crore.

Environment Considerations

This is an eco-friendly process with zero liquid discharge
