Process for preparation of liquid seaweed plant bio-stimulant (LSPB) from brown algae-sargassum

IPR Status & Details:

IN 201811029622

Application/Uses/Problem being addressed

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 including Competing Features/ Impact

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.

TRL Level & Scale of Development:- TRL 9 TRL Reference

Business scope & opportunity (in terms of scale, cost, market etc.)

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.

Environmental Considerations

This is an eco-friendly process with zero liquid discharge
